摘要： A system for hydrogenation C3 and C4 acetylenes contained within a hydrocarbon stream generated in a stream cracker unit where a debutanizer is placed upstream of a depropanizer for more economical processing of the hydrocarbon stream to produce lighter hydrocarbons, where the system requires only one stripper tower downstream of hydrogenation to remove residual hydrogen.

摘要： A system and a process for dimerizing cyclopentadiene (CPD) including producing a C6+C7 rich bottoms stream and a C5 rich side draw from a debutanizer, where the C5 rich side draw and at least a portion of the C6+C7 rich bottoms stream are directed to a dimerizer where the CPD is thermally dimerized to dicyclopentadiene (DCPD). DCPD is more stable than CPD and thus safer to handle.

摘要： A first stream containing 1,3-butadiene, C4 acetylenes, and optionally C3 hydrocarbons, is mixed with a portion of the liquid recycle stream from a C4 acetylene hydrogenation reactor containing hydrogenated C4 acetylenes and a molecular hydrogen-containing stream, the resulting mixed stream is then fed to a C4 acetylene hydrogenation reactor to selectively hydrogenate the C4 acetylenes in the crude butadiene stream without appreciable 1,3-butadiene conversion.
