    摘要： Methods and systems are provided for treating hydrogen sulfide rich sour gas through a series of fractionation columns. The processes disclosed herein and the variations thereof provide optimized processes for the removal of hydrogen sulfide from sour gas through the introduction of innovative azeotrope breakers, novel configurations of process equipment, and optimized operating conditions. Advantages of certain embodiments of the present invention include reduced equipment requirements, improved process efficiencies, reduced operating costs, and reduced capital costs. Other advantages include better process suitability to certain environmental conditions such as the arctic cold when compared to conventional amine treatment processes.

    摘要： The present invention is directed to methods for improving the efficiency of processes for the recovery of natural gas liquids from a gas feed, e.g., raw natural gas or a refinery or petrochemical plant gas stream. These methods may be employed with most, if not all, conventional separation methods using distillation towers, e.g., a demethanizer and/or deethanizer column. The methods of the present invention involve installing an internal refrigeration system consisting of an open cycle refrigerant withdrawn from a distillation column and a closed cycle refrigerant derived from the open cycle refrigeration system. A separator is installed downstream of the recycle compressor discharge cooler in the open cycle refrigeration scheme. At least a portion of liquid withdrawn from this separator is used as a closed cycle refrigerant by indirect heat exchange with the inlet gas or other process streams. Thus a closed refrigeration cycle enhances the performance of the open refrigeration cycle.
