Regarding the dilution gas in the butadiene extraction unit

Thread Content

My plant currently uses raffinate C4 for dilution; I’m wondering if it would be feasible to replace it with the butene-2 fraction from the downstream MTBE/butene-1 plant

Reply to 1# johnnywu1983: Dilution with low-value components is used (but butylene-2 has a high added value, so it’s not cost-effective); do you use chilled water condensation for recovery to obtain liquefied gas?

Reply 1# johnnywu1983: Is your styrene unit going to be overhauled? What’s the reason?

Sure. It can increase the device’s profitability.
