RPSEA Project 07122-12 TECHNICAL ASSESSMENT OF PRODUCED WATER TREATMENT TECHNOLOGIES 1st Edition Multi Effect Distillation – Vapor Compression Hybrid Both multiple-effect distillation (MED) and vapor compression evaporation (VCD) are state of the art technologies that have been employed for many years in desalination of seawater and brackish waters. More recently, hybrid MED-VCD has been employed to treat produced water (see more detailed discussion in commercial thermal technology processes). The combination of the two techniques to enhance the desalination process is frequently mentioned as a means of enhancing thermal desalination by reducing both capital and operating costs. This technology is favorable for replacing some of the older MSF plants. There is not much innovation in the design of such hybrids, but there are some complexities associated with the integration of the two processes. The advantages gained from combining the processes include: Increased production Expansion of capacity of existing MED units Enhanced energy efficiency For desalination, power consumption of MED-TVC plants is approximately 7.57 kWh/kgal (0.32 kWh/bbl) and there are no requirements to recirculate large quantities of brine [96]. The combination of high performance ratio and low power consumption results in lower overall energy costs. In the 1982, six MED-TVC distillers were operated in different remote sites of Abu Dhabi (UAE); each had a rated production capacity of 1.2 MGD [96]. Veolia Water Systems (France) installed an 11.1 MGD MED-VC system in Layyah (Sharjah, U.A.E.), which is claimed to have an energy efficiency of 50% over conventional systems. A barge mounted MED-MVC hybrid was built in Germany and shipped to Saudi Arabia. The advantage of such a system design and delivery method is that it minimizes local construction costs and shortens the interval between purchase and startup. A summary of the technical assessment of MED-VCD is listed in Table 25. Table 25. Summary of technical assessment of MED-VCD. 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. Has been employed for produced water treatment. Applicable to high TDS range, and all types of water chemistry makeup. Product water quality for MED-VCD plants is typically very high. Product water recovery is between 30% and 45% for seawater desalination. GE brine concentrator and crystallizer can increase water recovery to 75-85% [103]. Infrastructure considerations The infrastructure considerations or constraints are similar to that of MSF. Sufficient land must be available to accommodate the large plant footprint. The availability of low-pressure steam, either by dedicated generation or by cogeneration arrangements with adjacent power plants is essential. If using MVC, the system’s high the electrical demand must be considered. Energy consumption For desalination, power consumption of MED-TVC plants is only around 7.57 kWh/kgal (0.32 kWh/bbl) [96]. To achieve zero-liquid discharge, the energy demand for concentrate evaporation and crystallization is about 100 to 250 kWh/kgal (4.2 to 10.5 kWh/bbl) [102]. 68PDF Image | TECHNICAL ASSESSMENT OF PRODUCED WATER TREATMENT TECHNOLOGIES
