RPSEA Project 07122-12 TECHNICAL ASSESSMENT OF PRODUCED WATER TREATMENT TECHNOLOGIES 1st Edition range of feed water quality bins including produced water. MSF often requires centralized design and construction of large-scale plants. Formation of scale on heat transfer surfaces is a major operating problem in thermal desalination processes. It impedes the rate of heat transfer rates on condensing and heat transfer surfaces, and will consequently reduce the distiller performance. The majority of MSF plants are currently using scale inhibitors such as phosphonates or polycarboxylic and polymaleic acids in conjunction with mechanical sponge ball cleaning to control alkaline scale formation [96]. Acid cleaning may be required if scale formation is not controlled by using the scale inhibitors and mechanical cleaning. Well designed and operated, some MSF distillers have been in service for more than 20 years, and are expected to exceed 30 years [96]. This increases the cost effectiveness of process. A summary of the technical assessment of MSF is listed in Table 22. Table 22. Summary of technical assessment of MSF. Criteria Industrial status Feed water quality bins Product water quality Production efficiency (recovery) Description/Rationale Mature and robust technology for seawater and brackish water desalination. Can be employed for produced water treatment. Usually applicable to a high TDS range to 40,000 mg/L, and all types of water chemistry makeup. Product water quality for MSF plants is typically very high (TDS 2-10 mg/L), with little variation due to feed or concentrate salt content. Product water recovery is between 10% and 20% [94]. Infrastructure considerations The infrastructure considerations or constraints are large physical plant size. The technology relies on the availability of low-pressure steam, either by dedicated generation or by cogeneration arrangements with adjacent power plants. The MSF plants have low mobility. Energy consumption In addition to the 11 to 21 kWh/kgal (0.45-0.9 kWh/bbl) of energy required for electricity, the thermal energy needs for a MSF distillation plant is estimated at 0.8 million Btu/kgal (about 80 kWh/kgal or 3.35 kWh/bbl) [95]. Consequently, the total energy needs for MSF are between 70 and 112 kWh/kgal (or 3.35-4.70 kWh/bbl) [95] [100]. Chemicals Scale inhibitor and acid may be required for process control to prevent scaling. Corrosion control is achieved via pH control. Annual cleaning is typically conducted using acid, EDTA, or other antiscaling chemicals. Life cycle Typically 20 years, although most plants built in the 1970’s and 1980’s are still in operation with expected life of over 30 years. 60PDF Image | TECHNICAL ASSESSMENT OF PRODUCED WATER TREATMENT TECHNOLOGIES
