ABSTRACT:
According to the present invention, an inexpensive co-current and counter-current gas dehydration system, contactor apparatus, and operating method is provided which does not result in a need to clean equipment on a frequent basis. More specifically, there is provided a dehydration system, contactor apparatus, and method for removing water from a stream of wet natural gas which minimizes formation or iron sulfide scale within the contactor apparatus to maintain sufficient water removal capacity and to reduce operator cleanup and construction expenses. The instant invention improves the utilization of the water absorbing capabilities of glycol by using partially water laden glycol extracted from the central portion of the contactor apparatus in a co-current flow with wet natural gas to maximize the operating efficiency of the contactor apparatus.
