About this Unit

This unit is a comprehensive overview of the processing of natural gas from its extraction to the production of its major products: liquefied natural gas (LNG), liquefied petroleum gas (LPG), sales gas and a feedstock for the petrochemical industry. Students begin by learning about wellhead conditions, gas separation, transport and flow assurance, hydrates and their control, dehydration and the removal of contaminants, including CO2, H2S and Hg. LNG production covers precooling, cold section distillation, liquefaction, storage, transport and regasification. Emphasis is given to LNG refrigeration: basic thermodynamics, practical configurations and their optimisation. LPG production includes product specifications, C3 and C4 separation, condensate treatment and storage. Optimised configurations for sales gas production and gas distribution are covered. In addition, students learn about safety, risk management, material selection, control and economics related to natural gas processing.
