WebFor example, in an ethylene plant, the hydrocarbon feedstocks are cracked at temperatures between 1470°F and 1580°F (800°C and 860°C). The cracked gas is then quenched and cooled before it enters the compressor. The compressed crack gas goes through acid removal, drying and cryogenic separation processes (i.e. further fractionation) in WebThe areas of an ethylene plant are: steam cracking furnaces: primary and secondary heat recovery with quench; a dilution steam recycle system between the furnaces and the …
WebSep 17, 2024 · After compression, water must be eliminated from the cracked gas before the gas enters the cold zone because entrained water allows ice and gas hydrates to form once the temperature drops below 15°C (60°F), which may cause clogging. Drying is accomplished by utilising molecular sieve beds. These beds must be periodically … WebThe cracked gas compressor (CGC) is the critical system in modern ethylene plants. This compressor drives gases from the crackers for downstream separation. Few plants can afford the luxury of backup compressor trains. Any downtime or reduced capacity of the CGC negatively impacts olefin facility profits. Under this
