Evaluation of LNG Technologies Valerie Rivera, Ayema Aduku, Oluwaseun Harris Abstract Due to the increasing demand for natural gas in the world today, transportation of natural gas from different parts of the world has become a necessity. Liquefying the natural gas provides a safer and cheaper alternative for transportation and also increases its storage capabilities. There are numerous documented methods for the liquefaction of natural gas but only a handful of methods are actually implemented in industry today. The liquefaction process requires the natural gas to be cooled using various methods of cryogenic processes and also be depressurized to atmospheric conditions for easier and safer storage. With the most popular processes taking advantage of their huge market share, smaller and newer processes are being developed to operate more efficiently and with less utility costs involved. The analysis of eleven processes based on capacity, fixed costs and operating efficiency is discussed in this paper. Seven out of
