How is the residue left over from the production of ethylene through petroleum cracking typically disposed of?
Thread Content
Such as the propylene and isobutylene produced through cracking, etc.
The production of ethylene through naphtha cracking is a traditional method for manufacturing ethylene, and 99% of the ethylene produced worldwide is obtained via thermal cracking in naphtha tubular furnaces. Naphtha tubular furnaces are used for thermal cracking to produce main products such as ethylene and propylene, while also generating by-products including mixed C4 hydrocarbons, hydrogen, methane, pyrolysis gasoline, pyrolysis diesel, and pyrolysis fuel oil.
Are there any data on the yield ratio or something like that? How much ethylene can be produced from one ton of naphtha?
It depends on the composition of the naphtha and its boiling range; yields vary for different compositions and boiling ranges.
