Process selection and recent design innovations for LNG plants—Part 1

I. S. Al-Mutaz, I. Wazeer and R. Khan, King Saud University, Riyadh, Saudi Arabia; and A. Chafidz, State University of Semarang, Semarang, Indonesia Global LNG demand is increasing rapidly because natural gas is considered to be the cleanest-burning fossil fuel. Other features of LNG include low carbon dioxide (CO2) emissions, ease of transport, sustainable development and energy security. Different types of natural gas liquefaction plants have been developed globally to meet rising demand for LNG. The selection of LNG technology involves parameters such as equipment (e.g., compressors, turbines, heat exchangers, etc.) and process definitions (e.g., pressure levels, temperature range, type
