Abstract:
A process is present for increasing the yields of 1,3 butadiene. The process includes recovering 1,3 butadiene from a cracking unit that generates a crude C4 stream. The 1,3 butadiene is separated and the remaining C4 process stream components are further reacted and dehydrogenated to generate 1,3 butadiene in a subsequent process stream. The subsequent process stream is recycled to recover the additional 1,3 butadiene.

Claim (Index 9):
The process of  claim 1  wherein the butadiene separation system comprises:\n passing the steam cracked process stream to a first absorption separation column, and passing a solvent to the first absorption separation column, to generate a raffinate stream comprising butenes and butanes; a first intermediate stream comprising butadienes, vinylcyclohexene and ethylacetylene; and a first bottoms stream comprising butadienes, vinylacetylene, ethylacetylene and solvent; \n passing the intermediate stream to a second absorption separation column, and passing a solvent to the second absorption separation column, to generate a second overhead stream comprising butadienes, methylacetylene and vinylcyclohexene and pentenes; and a second bottoms stream comprising acetylenes and solvent; and \n passing the second overhead stream to a first fractionation column to generate the first butadiene stream and an third overhead stream comprising methyl acetylene and butadiene.
