Steam Cracking - an overview ScienceDirect Topics

In steam cracking, a gaseous or liquid hydrocarbon feed like naphtha, LPG, or ethane is diluted with steam and briefly heated in a furnace in the absence of oxygen. Typically, the reaction temperature is very high, at around 850 °C. The reaction occurs rapidly: the residence time is on the order of milliseconds. Flow rates approach the speed of sound. After the cracking temperature has been reached, the gas is quickly quenched to stop the reaction in a transfer line heat excha… WebCalculations for carbon dioxide, methane, and ethane are carried out by the peak-height measurement method. b) Ethane Feeder Pipeline Temperature Measurement The temperature is measured by a thermocouple at site and recorded in a distributed control system.
