Recently, the butadiene unit of the C4 Aromatics unit of the Sino-Korea Petrochemical Epoxy Aromatics Unit was affected by the composition of the raw materials.
The excess C4 raw materials sent to the MTBE unit were reduced.
In order to increase the feed load of the MTBE unit, the company Decided to change the MTBE unit C-503 bottom to butadiene unit diluent gas flow to provide diluent gas
.

Use the remaining C4 at the bottom of C-503 instead of C4 from the butadiene unit as a diluent.
The saved C4 can be supplied to the MTBE unit as a raw material to increase the production load and produce more MTBE and butene- 1 product, and can bring considerable economic benefits
