Ethylene Production

Ethylene production

 

Ethylene is produced in the petrochemical industry by steam cracking. The cracking process converts saturated hydrocarbons into smaller, often unsaturated, hydrocarbons.Ethylene is separated from the resulting complex mixture by repeated compression and distillation. The process also results in the slow deposition of coke on the reactor walls that degrades the thermal efficiency and wear of the reactor. An ethylene cracking furnace usually requires de-coking every few months. In the de-coking process, the hard solid coke layer on the wall of coils is heated by steam or air and converted to carbon monoxide and carbon dioxide.

Key measurements include:

  • O2 (oxygen) - to monitor combustion efficiency in the cracking furnace

  • CO (carbon monoxide) and CO2 (carbon dioxide) - to measure status of cracking and de-coking processes

  • H2S (hydrogen sulphide) - to monitor the efficiency of the caustic scrubber clean-up process.
