A novel hybrid adsorption/ion exchange (IEX)/reverse osmosis (RO) process is proposed for produced water desalination. Water in liquid phase at high pressure and temperature is utilized to regenerate the adsorber. This has multiple advantages for strongly adsorbed components including better desorption with less regeneration fluid, lower energy requirements because there is no phase change, and lower costs. IEX regeneration with RO retentate eliminates added chemicals. Optimized process to minimize costs at three different brine disposal costs. Hybrid process water recovery up to 86% is feasible and economical for the produced water considered in this work. This work is based on computer modeling for process synthesis, design, and optimization. Experimental studies are needed to verify the assumptions made in this analysis.
