Butadiene extraction acetonitrile process
Thread Content
Butadiene extraction process: High content of isobutylene at the bottom of the extraction column – should the amount of solvent be increased or the solvent feed rate be reduced?
Hello, it is recommended that you first check the fluctuations in the butadiene content in raw material C4. If there are significant fluctuations, meaning a decrease in the butadiene content, then you can appropriately reduce the amount of acetonitrile fed in, as well as minimize reboiling and reflux. If the fluctuations are small, appropriately increase the bottom temperature of the extraction column, paying attention to the butadiene content at the top of the column!
