Abstract

Liquefy Natural Gas (LNG) is the liquid phase from the Natural gas that extracted and purified. Natural Gas manufacturer turns gas to liquid to make more storage space and to make transportation easier. To turn the natural gas to liquid, the gas needs to cool down to -160ᵒC. The real challenge is not to make the gas liquid the real challenge is to keep the gas liquid because the temperature difference with surround is big which is made some of the liquefied natural gas to vaporize again. Engineers found some techniques to re-liquefy the gas. This research paper explains some of the available thermodynamics cycles and how it works. Moreover, it will cover the economic side and how to optimize the process and make it more efficient with low consumption in money and energy. This study has been done through Aspen HYSYS (simulation base) for few cycles to choose the best cycle. This study will consider Malaysia environment as the surrounding environment for the project. This project will cover only the simulation method.
