Waste Heat to Power Cycle

ROT - Radial Outflow Turbine 

 

Our ROT turbines are made in the USA at our shop in the Pacific Northwest. Our turbine shop has a Waterjet Machining Center and High Speed Vertical Milling CNC Machine, which allows us to build any size turbine from 5 inches diameter to 24 inches in diameter, which covers the range from 2 kW to 250 kW+ in output power.

 

Low RPM = No Gearbox Needed  

 

The advantage of a ROT turbine is that it is a lower RPM turbine, which allows a direct drive to a standard 1,800 or 3,600 RPM generator. It also allows the use of either 50 hz or 60 hz DC or AC. Pressurized flow enters from the front of the turbine, and is expanded outwards to the perimeter of the turbine through several stages. Inlet flow is first directed by stators (stationary foils) into the first stage on the rotor, then through another set of stators to another stage on the rotor. The expanded gas exits on the perimeter of the rotor, and finally exits out the back of the turbine. Because the lower RPM allows a direct drive generator, it eliminates the need for a gearbox which is typical on high speed turbines. The gearbox is added cost, and has to be rebuilt every 3-5 years. Lower RPM also allows the use of slower speed shaft bearings, which increases the longevity of the the machine operation, and less frequent maintenance intervals. Low RPM Turbines and Small ORC Systems Can Capture 95 Percent of World's Waste Heat

The prevailing large turbine generator wisdom right now in the commercial market is for high-speed, complex turbines that drive a high speed generator, which requires expensive switchgear and grid-tie equipment. Our philosophy at Infinity Turbine is to keep the technology as advanced and simple as possible, using as much off-the-shelf components as possible to keep costs within a reasonable payback period of 3 years or less. This cost effective approach will allow more utilization of low grade waste heat, under the 500 kW system size, which we estimate is 95 percent of the worlds available waste heat (that is accessible and available for use).

 

Very few equipment manufacturers are in this smaller (sub-500 kW) market, because they cannot cost effectively manufacture the equipment, since most of it is custom built using expensive components. Infinity Turbine seeks to challenge this conventional market strategy, and produce a system that is affordable in terms of a short payback period in electrical production cost savings, from using a low grade temperature waste heat source.

Produced water accounts for approximately 80 percent of the total waste volume for the oil and gas industry, and presents both an environmental concern and an economic constraint to oil and gas development.

 

If your well produced water is at least 90 deg C (or around 194 deg. F) then you may be able to utilize that waste heat through our organic Rankine cycle Infinity Turbine to generate electricity, to run your downhole pumps or even sell back to the grid.   

 

 

We can also provide a robust hot water or steam maker from our shaft powered cavitation module.  This allows you to use less-than-boiling-point system input temperatures to make steam.  An example of this might be the waste heat from a diesel gen set, geothermal, solar, or other low grade heat sources  that are used to provide heat to run our Infinity Turbine.

 

What are the uses for steam ?  Desalination, cleaning, oil well enhanced recovery (EOR) and many other applications.

Here's a recent article regarding producer water and power generation (note this is from the article "Geothermal Potential in the Gulf of Mexico" published recently in Renewable Energy World):

 

Geothermal Potential in the Gulf of Mexico

 

"Considerable geothermal energy potential exists in the Gulf of Mexico and onshore in Louisiana, Texas, Alabama and Mississippi. Two types of geothermal resources are of particular interest in the Gulf area: “geopressured” geothermal and “oil field co-produced” geothermal resources.

 

The Basics

 

Let me begin with some basic background information:

 

A geopressured resource consists of hot brine (salty water) saturated with methane (natural gas) found in large, deep aquifers that are under higher pressure due to water trapped in the burial process. These resources are often found at depths of 3 to 6 km (2 to 4 miles). Water temperature can range from 90 to 200 degrees C (190 to 390 degrees F). Geopressured resources are present in several areas of the country, ranging from California and the Dakotas to Texas, Louisiana and Alabama. This prime resource is considered to be abundant in the area around the Gulf of Mexico, both onshore and offshore.

 

An oil field co-produced resource makes use of wells already drilled by the oil and gas industry that are either deep enough to encounter hot water, or could be deepened into these hot zones. To the oil industry, producing hot water is at best a nuisance. It is difficult to handle, costs money to pump, and has to be reinjected at an additional cost. What better way to use this hot water byproduct than to produce free, renewable, reliable electricity?

 

Southern Methodist University (SMU) researchers have documented the large amounts of hot water produced by existing oil and gas wells. In West Texas, for example, for every barrel of oil produced, nearly 100 barrels of hot water are co-produced. In 2002, Texas produced over 12 billion barrels of waste (often hot) water as a byproduct of oil and gas extraction, which was reinjected into the ground at a cost to the producer.

 

While the extent of oil field co-production is still being assessed, research has identified numerous states where significant hot water is produced from oil and gas wells, including Texas, California, Florida, West Virginia, Colorado, Wyoming, Montana, North Dakota, New Mexico, Oklahoma and Utah.

 

Potential

 

The energy potential of these resources is enormous. Experts estimate that geopressured resources could hold as much as a 200-year supply of gas for the entire U.S. at 2002 levels of demand. That’s not even considering the thousands of megawatts (MW) of thermal energy potential from the hot brines. If realized to its full potential, geopressured resources could double the total recoverable natural gas in the United States and meet a significant portion of our electricity needs.

 

Producing energy from oil and gas fields in Texas alone could produce between 400 - 2200 MW of geothermal power, according to SMU scientists. Looking at all of the oil field production potential, significantly more power production is possible, with estimates in the tens of thousands of MW.

  

The National Renewable Energy Laboratory (NREL) recently published a report tiled, Geothermal -- The Energy Under Our Feet, which estimates that co-produced and geopressured resources could supply as much as 70,000 MW of new power -- 10% of our total national electric power needs -- in the next 20 years. Today, geothermal resources supply about 0.3% of US electricity needs, so 10% represents a significant jump.

 

Outlook for Development

 

Production from geopressured resources has been completed on a demonstration basis in the past. The US Department of Energy (DOE) built a pilot power plant using a converted gas well in Brazoria County during 1989 and 1990. The project was technically successful, but after 6 months of operation the power plant was dismantled because the low price of gas at that time made the project uneconomic. Today, higher energy prices coupled with national security concerns have regenerated interest in the development of geopressured resources. With changes in the market and advances in technology over the past fifteen years, geopressured resources are once again being considered.

 

Production of geothermal power from oil and gas wells is a relatively new topic of discussion. One new technological development that has helped raise interest in the co-production of electricity from oil fields is the advent of small power technology that produces energy at lower temperatures. "

 

Small-scale geothermal power technology, like that being developed by Infinity Turbine demonstrate that small units (250 kilowatts) are feasible at relatively low temperatures (165 degrees F). This technology is one solution which is needed to tap the large amounts of hot water produced from oil fields.

 

State of Texas - Enhanced Geothermal Potential

Although Texas is well known for its vast oil and gas industry, the state is rapidly emerging as a leader in the investigation of its significant geothermal energy resources. Thousands of oil and gas wells drilled deep into the Texas landscape have enabled the comprehensive evaluation of subsurface geology and heat flow characteristics. Three general types of geothermal resources have been identified within Texas: hydrothermal systems, geopressured systems, and hot dry rock (HDR). High bottom hole temperatures (BHTs) have been found in wells within the deep sedimentary basins throughout West Texas and the Panhandle. High-temperature hydrothermal reservoirs are plentiful within the Permian Basin near Midland, and geothermal fluids with varying temperatures are present statewide. Once considered a nuisance, hot water encountered during petroleum production is attracting increasing interest due to the energy potential it offers. Geopressured resources consisting of hot fluids under high subsurface pressure are prevalent along the Gulf Coast. The eastern portion of Texas exhibits geopressured resources and areas of HDR, or high-temperature rock formations that are impermeable to subsurface fluids. The production of electrical power using geothermal energy has been demonstrated in Texas, and there is also potential for the direct use of thermal energy from geothermal fluids for applications such as space heating and aquaculture.

Current Development

A geothermal power plant was operated from 1989 to 1990 for testing purposes in Brazoria County in the Gulf Coast region. The plant was unique in design with a hybrid-cycle, allowing for the generation of electricity from geopressured fluids, as well as entrained natural gas, with a total capacity of 980 kilowatts. The plant's output, enough to power approximately 1000 typical households, was sold was sold to a local utility during the demonstration period. Although this project was a technical success, the geothermal system was not cost-competitive in comparison with conventional petroleum-based power production at the time.

Renewed efforts to utilize the geothermal resources of Texas have come with a focus on using existing oil and gas infrastructure to generate and transmit electricity. Wells currently drilled for petroleum extraction often reach the depths necessary to access moderate to high-temperature (above 100°C) geothermal fluids. Millions of gallons of hot water produced from these wells are routinely regarded as a waste product. However, modern geothermal technologies such as modular units and binary power plants can make use of the hot water by-product to generate electricity on-location in the oil fields. Electricity produced in the field can be used to power site operations, while existing transmission infrastructure can deliver excess power back to the grid. In Texas, private companies have undertaken research projects to demonstrate the generation of electricity in oil and gas settings, and commercialization of the technology is projected to take place within the next decade.

Scientists at the Southern Methodist University Geothermal Laboratory in Dallas have projected that several thousand megawatts of electricity-enough to meet the demands of millions of households-could be generated from the current rate of hot water production from oil and gas wells throughout the United States. In addition, infrastructure within depleted oil fields that would otherwise be abandoned can be retrofitted for power production from the remaining geothermal resource. Interest in the potential for using geothermal energy in oil and gas settings has extended beyond Texas to other petroleum-producing states such as Wyoming and Louisiana. Research is also ongoing to find ways to extract energy from HDR through Enhanced Geothermal System (EGS) techniques that involve strategically fracturing bedrock and introducing fluids to create hydrothermal reservoirs.

Waste Heat Power Generation  

 

This unique system allows you to use your flare gas, waste heat, waste hot water, geothermal, geo-pressurized, hydrothermal, enhanced geothermal, turbine exhaust, or re-injected waste water to power a organic Rankine cycle (ORC) turbine generator.

 

The worlds most cost-effective untapped renewable energy source is waste heat.  While primary energy production as well as industrial infrastructure is all around us, very little of the heat byproduct has been resourced as a secondary energy source.

 

To capture, utilize, and profit from that waste heat is the challenge which has been overlooked until recently by Infinity Turbine LLC.

 

Geothermal and Waste Heat Organic Rankine Cycle:

The technology developed using a ORC (Organic Rankine Cycle) can operate off any heat source, with a minimum of 125 deg F temperature differential between the heat source and cool liquid flow heat sink.  Geothermal energy is only one potential application.  Similar systems are already in operation off heat generated from landfill flares and gas turbine exhaust.  Other applications may include using biomass as a fuel.  

 

Outflow Radial Turbine

 

Infinity Turbine LLC offers complete ORC systems, as well as our Build-Your-Own-Brand Program.

 

Build Your Own Brand

 

If you would like to assemble your own Organic Rankine Cycle Waste Heat to Energy System, Infinity sells the core of the system, the turbine/expander. You can also use our core turbine to make intermediate models specific to your market.  

 

Build Out Your System Using Our Turbine: You can build or purchase the parts and use our plans with consulting to guide you along the way. Purchase the parts and assemble the system.

 

This allows you to use locally available components to save on shipping, while giving your the opportunity to build your own brand to sell to your customers.  You may choose to manufacture the necessary components, or purchase them from suppliers.  Of course we can sell you the components, or refer you to suppliers.  We supply the support, from manufacturing, assembly, start-up commissioning to training.

 

Sell Local or Sell Global: Using our core turbine/expander, you can stay local or go global with your ORC system with the security of knowing that the turbine is standardized.  The key component to any ORC system is the turbine/expander.  Most of the cost associated with the development and manufacture of ORC systems is with the turbine/expander.  

 

Infinity Turbine core technology inside:

 

Using this strategy, we have taking all the years of research and development out of the equation, which allows you to rapidly assemble and deploy your ORC machines to your customers.  Infinity is constantly making its turbine more efficient as well as the design of the ancillary components which make the ORC system work.  Some of our technology which leads other ORC manufactures is our implementation of nano-fluid technology which enhances the heat transfer in both the evaporator and condenser. Using a nano-fluid additive makes the system more efficient.

 

Why Low Temperature Waste Heat ?

 

Infinity Turbine LLC has studied waste heat availability worldwide and has assessed the market to recover that heat which we believe 95 percent is at or below the 100 C (212 F) range.  Organic Rankine Cycle is more efficient at this range than the Kalina Cycle.  For the small amount of the market which has high heat available (well above 100 C) you can use steam systems.  Organic Rankine Cycle uses refrigerants as the working fluid which boil below 100 C (212 F).  The pressurized vapor can then be expanded through a turbine to spin a generator.  

 

Why Smaller ORC Systems ?

 

Of the very small number of ORC manufactures, most focus on above 500 kw/hr output.  The few big players focus on above 1 MW/hr output.  Yet more than 95 percent of the availability of waste heat world wide is available to the smaller system size.  For this reason, we are focusing on small ORC systems which allow the ORC user to capture and profit from low grade heat.

 

Why Install a ORC Machine ?

 

Capturing low grade heat which would otherwise be vented to the atmosphere can be used to generate rotational horsepower.  This can be used to power a electrical generator, or other rotary equipment such as pumps.  In addition, the exiting, heat from the turbine can be used in CHP (Combined Heat and Power) applications to heat water, desalination, or even in adsorption chillers to make chilled water, ice, or air conditioning.

What is Infinity Turbine technology on the leading edge ?

 

All of our turbines now feature the modular block technology which utilize the hexagon housing blocks that bolt together with standardized bolts.  

 

The modular block was invented Greg Giese to allow rapid prototyping of any process which involves fluid handling.  Originally designed for gas to liquids technology, Greg ported the technology to turbines.

 

This is the first time in history that a turbine was built specifically to incorporate a modular building block design, that allows prototype to commercial product in one device. During a SBIR review, the National Science Foundation remarked that the modular block was a "Industrial Lego."

 

The functionality of the modular block housing allows interchangeable turbine cores specific to working fluids (steam, ORC refrigerants, liquids, etc.) and can even employ backpressure vs. condensing turbine routines.

 

The modular block can be made from a host of materials depending on working pressure and temperature.  This includes stainless steel, titanium, carbon fiber, ceramic and even plastic.  The hexagonal shape (similar to the structure of a beehive in nature) has great structural integrity and strength.  

 

Ceramic or stainless steel bearings are utilized for a long running life.  In the small scale applications, the refrigerant is the bearing lubricant. Larger turbines direct drive AC generators.

 

Infinity is also working with enhancing heat transfer in pool type heat exchangers (shell and tube).   Utilizing a nano-technology additive, studies from NIST have shown that increases of 50-200 percent increases in heat transfer may achieved within common refrigerants.

 

Infinity Turbine LLC is the worlds leading ORC turbine technology innovation company, deploying state of the art concepts and designs.

 

 

Publications for ORC Applications

 

Want to learn more about Organic Rankine Cycle, and producing power from a hot liquid ?  Then check out our publications section.  We're the only ORC company in the world that has scanned in the majority of US Government publications on ORC energy.

 

Oil and Gas

 

The oil and gas also provides another possible application for the ORC power plant.  Because most oil and gas wells are quite deep, they are warmed by the natural thermal gradient of the earth.  In 2004 the U.S. produced over 2 billion bbl of “waste” water along with the oil and gas production, primarily from the Gulf States with temperatures high enough to produce electricity.  This hot water could be used to generate power directly, without impacting oil and gas production.  

 

Gas turbines used for compressors and power generation provide huge amounts of waste heat.  This can be converted to additional electrical power.

 

Organic Rankine Cycle

The Global Energy INFINITY TURBINE (turbogenerator) operates using the Organic Rankine Cycle (ORC). The Organic Rankine Cycle (ORC) is similar to the cycle of a conventional steam turbine, except for the fluid that drives the turbine, which is a environmentally friendly low boiling point organic fluid which allow the system to run efficiently on low temperature heat sources to produce electricity in a wide range of power outputs.  Typical ORC range for this equipment is 80 - 110 C.

 

The Cycle

 

The environmentally friendly organic working fluid is turned into vapor by application of a heat source in the evaporator. The organic fluid vapor expands in the turbine and is then condensed using a flow of water in a shell-and-tube heat exchanger (alternatively, ambient air can be used for cooling). The condensate is pumped back to the evaporator thus closing the thermodynamic cycle. Heating and cooling sources are not directly in contact with the working fluid nor with the turbine. The condenser can use ground source geothermal and air cooled for added efficiency.

 

For high temperature applications such as Combined Heat and Power (CHP) biomass-powered boilers, high temperature thermal oil is used as a heat carrier and a regenerator is added, to further improve the cycle performance.

 

Advantages of CHP in combination with ORC

 

a. High system efficiency

b. Good turbine efficiency

c. Low mechanical stress of the turbine, due to the low peripheral speed

d. Direct drive AC generator (IT50 and above) - no gearbox needed

e. No erosion of blades, due to the absence of moisture in the vapor nozzles

f. Long life

g. No operator required

h. Can be serviced by standard refrigerant technician

 

The system also has practical advantages, such as simple start-stop procedures, low noise operation, minimum maintenance requirements, and good part load performance.

 

Modularity

 

Larger units are composed of multiple modules, pre-assembled at the factory in shipping containers. Because of that, units are easy to transport and to install, and they are easy to interface with the hot and cold sources on site.  Since they are container mounted, you can stack and tie together horizontally, or vertically.  You can even use them on ships.  Perfect for remote operations, like islands.
