A cascade liquefaction process typically utilizes three pure-component refrigerant loops: propane, ethylene, and methane. Feed gas is
pre-cooled as it passes through the propane chiller before undergoing liquefaction and sub-cooling through ethylene and methane cold
boxes. Most recent variations of the process produce 4.5 — 5.2 mtpa per train. Greeneld plants will commonly consist of one to three trains
with room for additional trains depending on long term feed gas supply.
