LNG Systems

The demand for more environmentally friendly energy sources has given considerable impetus to the use of natural gas. Sourcing natural gas from producers to consumers over long distances is best accomplished by liquefying the natural gas to −161°C. However, treating the produced gas, cooling it to cryogenic temperatures to convert it into Liquefied Natural Gas (LNG), storing it for prolonged periods of time, transporting it with specialised LNG ships and possibly storing it again presents some unique engineering challenges. Class LNG Systems covers all aspects of the LNG supply chain from LNG markets, gas compression, natural gas processing, cryogenic cycles, storage facilities, and LNG carriers. Particular emphasis is placed on the thermodynamics of the LNG cooling cycles, boil-off gas generation, above and below ground storage tanks, LNG containment systems, LNG hazards, and safety matters. Below we share some of the material taught in OGEE-522 LNG Systems, during Fall 2020, at the University of Nicosia:
