Ethylene Plant Doubles Production and Increases Profitability with New Gas Cooling Injectors

Ethylene Plant Doubles Production and Increases Profitability with New Gas Cooling Injectors Problem: An ethylene producer in China needed to spray quenching oil into a gas stream to cool the temperature from 400°C to 170°C (750°F to 340°F). They were using eight, large (8”) full cone nozzles for cooling in the original process line. To increase total ethylene production from 600,000 tons/year to 1.2 million tons/year, the producer was adding
