WATER TREATMENT ARRANGEMENT FOR STEAM-ASSISTED OIL PRODUCTION OPERATION

WATER TREATMENT ARRANGEMENT FOR STEAM-ASSISTED OIL PRODUCTION OPERATION

A water processing arrangement (18) for steam assisted oil production, having a water softening system (30) configured to remove silica from a stream of producer well water (64, 66) using a caustic (70), and an electrodeionization-based water deionization system (36) downstream of the water softenin...

Zusammenfassung:A water processing arrangement (18) for steam assisted oil production, having a water softening system (30) configured to remove silica from a stream of producer well water (64, 66) using a caustic (70), and an electrodeionization-based water deionization system (36) downstream of the water softening system configured to deionize the stream of water (66) A byproduct of the electrodeionization is caustic NaOH which is recycled to the softening system
