iv) Operation and maintenance costs – Streams with high chemical activity that damage equipment surfaces will lead to increased maintenance costs. v) Environmental concerns – Waste heat recovery from exhaust stream may complicate or alter the performance of environmental control and abatement equipment. vi) Product/Process control – Chemically active exhaust streams may require additional efforts to prevent crosscontamination between streams. 5) ApplicationSpecific Constraints i) Processspecific constraints – Equipment designs are processspecific and must be adapted to the needs of a given process. For example, feed preheat systems vary significantly between glass furnaces, blast furnaces, and cement kilns. ii) Product/ Process control – Heat recovery can complicate and compromise process/quality control systems 6) Inaccessibility/Transportability i) Limited space – Many facilities have limited physical space in which to access waste heat streams (i.e., limited floor or overhead space) ii) Transportability – Many waste heat gaseous streams are discharged near atmospheric pressure (limiting the ability to transport them to and through equipment without additional energy input). iii) Inaccessibility – It is difficult to access and recover heat from unconventional sources such as hot solid product streams (e.g., ingots) and hot equipment surfaces (e.g., sidewalls of primary aluminum cells). Safety and operational demands that require egress/access around/above most melting furnaces, boilers, heaters, and other high temperature equipment. 5.8 Summary of Research, Development, and Demonstration Opportunities for Waste Heat Recovery In order to promote heat recovery practices, several efforts could be made to reduce system costs, optimize heat exchange materials, heat transfer rates, lowtemperature recovery, and available enduses for waste heat. Opportunities for RD&D that address technology and cost barriers are listed below. • Lowcost, novel materials – Develop lowcost, novel materials for resistance to corrosive contaminants and to high temperatures. • Reduce overall costs – Economically scale down heat recovery equipment and reduce relative costs for smallscale operations. • Easier maintenance – Develop economic recovery systems that can be easily cleaned after exposure to gases with high chemical activity. • Process improvements – Develop alternative manufacturing processes that generate less waste heat. Or, develop processes that avoid introducing contaminants into process offgases, thereby enabling easier heat transfer from exhaust gases. Of course, both must retain acceptable product quality and financial returns. • Gas cleaning – Develop lowcost methods for cleaning exhaust gases. 63 PDF Image | Waste Heat to Energy Tech Opportunities in US Industry

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
