Project Description

GE Global Research, in cooperation with Pennsylvania State University, will leverage new technology to develop a cost-effective water recovery process from high salinity extracted formation water. The project objectives are to: define a scalable, multi-stage extracted water desalination system that yields clean water, concentrated brine and, optionally, salt from saline brines (180,000 ppm total dissolved solids, TDS) and that meets a cost target; validate the overall system performance with field-sourced water using GE pre-pilot and lab facilities, and define the scope and identify a team and test location for pilot-scale implementation of the desalination system. Carbon sequestration facilities will be screened to identify a potential source and composition of extracted water, as well as to identify a partner with whom GE will conduct a pilot water recovery project (Phase 2, separate project). Based on the extracted water composition, a cost-effective water recovery process comprising pretreatment, brine concentration, and, optionally, salt crystallization, will be developed based on techno-economic modeling, which includes rigorous process modeling based on Aspen Plus/OLI systems software. A combination of established and new, pilot-ready pretreatment and brine concentration technologies will be evaluated with respect to cost and performance in order to identify the most cost-effective water recovery process.

Project Benefits

Successful execution of this project has the potential to dramatically increase the capacity of deep saline formations for CO2 storage with minimal cost impact. The project could also serve as a basis for pilot validation of new, low-cost water pretreatment and desalination technologies.
