Produced Water Treatment Using Switchable Polarity Solvent Forward Osmosis (SPS FO) Technology

摘要

Process and economic modeling suggest that the SPS FO water treatment process can economically treat approximately 90% of a produced water feed stream with salinity similar to that of seawater. If the produced water feed stream is supplied at a temperature of ～100°C, SPS FO process thermal energy requirements could be met entirely through use of heat provided by the feed stream. If the produced water feed stream is supplied at a temperature in excess of ～120°C, SPS FO process electrical and thermal energy requirements could potentially be met using energy in the feed stream.
