Regarding the separation of ethylene cracking gas
Thread Content
I would like to ask the seniors: what are the approximate composition ranges of the gas at the top of the deethanizer and the gas at the top of the depropanizer during the sequential separation process after hydrogenation of ethylene cracking gas? I urgently need these data for my current research project, but no complete set of them could be found through literature and patent searches. I hope the seniors can provide some data for reference. Thank you.
The top product of the deethanization tower is mainly ethane and ethylene, while the top product of the depropanization tower consists of C3 compounds
Ours is a high and low pressure depropanization tower
The top of the high-pressure depropanization tower contains C1 and C2 components, while the top of the low-pressure depropanization tower contains C3 components
