Upstream LNG Technology


This course discusses in depth the various processes related to upstream LNG technology. The importance, sources and types of natural gases, properties and phase behavior of natural gas, dehydration of natural gas, removal of natural gas hydrates , nitrogen gas and acid gas. Natural gas liquid, sulpher and trace component recovery, Compression of natural gas and Liquefaction of natural gas will be explained to a good extent.
