Acetylenes-free Butadiene by the KLP~TM Process

摘要

UOP's KLP~TM process plays a key role in helping petrochemical producers meet the increasing demand for butadiene in the mos teconomical way. In North America and Europer, polymer-grade 1,3-butadiene is required to have no more than 20 wt-ppm C_4 acetylenes. In the Far East, ttraded 1, 3-butadiene may contain as much as 50 to 200 wt-ppm C-4 acetylenes. the KLP process can be used to selectively hydrogenate all of the C_4 acetylenes in a crude C_4 stream, typically present at 1 wt-
