Oil and Gas Engineering

Description

Physical properties: Liquid-vapor equilibrium, density, ratio of vapor methane/LNG, heat of vaporization, heat of combustion- Safety aspects: flash point, fire point, auto-ignition point, minimum spark energy, flammability limits, deflagration- LNG vaporization- Rapid Phase Transition (RPT)- radiation levels- stratification/roll-over, sloshing, LNG clouds ignition- Asphyxiation risks, cryogenic liquids jets, piping behavior. Feed pretreatment: sweetening, dehydration, LNG extraction, Hg and aromatics removal- Different liquefaction processes: pure component refrigerants, pure component(s) and mixed refrigerant(s), mixed refrigerants- Peak shaving simplified scheme- Regasification process- LNG tanks: single or double or full containment (self-standing, membrane). Hazards- Jetty head, jetty trestle, harbor- LNG carriers: common features, technology, cargo operations, safety systems.
