Power Plant Uses Membrane Contactors To Remove CO<sub>2</sub> From Water

A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO2 inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO2 to reduce the load on the equipment and improve the water quality.
