UOP Inc. has acquired the KLP process for selective hydrogenation of acetylenic compounds in crude butadiene streams from Dow Chemical U.S.A. The acquisition of KLP adds to the family of selective hydrogenation technologies available from UOP. The company has assumed all associated licensing, engineering, marketing, catalyst supply, research and development, and technical support responsibilities.

The KLP process achieves essentially complete acetylene conversion with little or no hydrogenation of butadiene. A net gain of butadiene across the KLP unit may result, depending on the concentration of acetylenic compounds in the crude butadiene stream. The process can be retrofitted to an existing butadiene complex to increase product quality or to debottleneck the unit. The inclusion of KLP makes possible the recovery of the highest purity butadiene.
The KLP process was developed and commercialized by Dow. There are currently six operating KLP units, and five licensed units in the design or construction phase. Two more units are expected to be on stream by late 1991 or early 1992.
