THE C3MR LIQUEFACTION CYCLE:VERSATILITY FOR A FAST GROWING,EVER CHANGING LNG INDUSTRY

摘要

New LNG plants face a broader range of process requirements than ever before.These requirements are being driven by worldwide growth in LNG demand and the development of feed gas supplies in new and existing geographic locations.As a result,facilities must be designed to meet a number of new challenges.For many years,the propane pre-cooled mixed refrigerant(C3MR)process has remained the dominant liquefaction cycle.The versatility of this cycle makes it well-suited to accommodate this ever changing industry. This paper describes the technology advancements in process,machinery,and the main cryogenic heat exchanger that have played a key role in meeting the wider range of process requirements. 139
