Conventional processing schemes for desulfurizing, drying, and separation of natural gas liquids from natural gas streams require treating the gas by a different process for each separation step. In a simpler process, based on the University of California, Berkeley Sulfur Recovery Process (UCBSRP) technology, hydrogen sulfide, propane and heavier hydrocarbons, and water are absorbed simultaneously by a polyglycol ether solvent containing a homogenous liquid phase catalyst. The catalyst promotes the subsequent reaction of hydrogen sulfide with added sulfur dioxide to produce a high quality sulfur product. Hydrocarbons are separated as two product streams with the split between propane and butane. This new process offers an overall reduction in both capital and energy costs.
