GENERAL
DESCRIPTION
|
|
1,3-Butadiene is extracted with C4 mixtures from Naphtha
cracking. Its purity is over 99.5wt% using DMF(dimethyl formamide) as extracting
solvent. Remained C4 raffinate after extraction takes addition of hydrogen to
use for producing C4 LPG, or MTBE by a reaction with methanol. |
