Abstract –For more than thirty five years, Air Products and Chemicals. Inc. has been the leading supplier of natural gas liquefaction technology and Keywords: LNG Liquefaction main cryogenic heat exchangers. The majority of LNG produced today comes from plants utilizing 1. Introduction Air Products’ propane pre-cooled, mixed refrigerant LNG process (C3MR) and MCR® Mixed refrigerant processes, and specifically Wound Coil heat exchangers. New LNG plants the propane pre-cooled, mixed refrigerant process, face a broader range of requirements than ever have taken a commanding position in the liquefaction before. Growth in LNG demand is faster than ever of natural gas because they are flexible, efficient, and before, larger process train size is often desirable, low cost. The C3MR process is operating efficiently in new geographical locations for liquefaction plants arid and tropical climates, with rich and lean natural and new customers for LNG with different LNG gas feed, with and without LPG (C3 and C4) specifications are emerging, as well as FPSO extraction, over a broad range of ambient temperatures. applications. LNG train capacity has continued to
