Processes detergent Olex

There are three liquid-phase adsorption Sorbex technology-based separation processes for the production of olefins. The first two are the UOP C4 Olex and UOP Sorbutene processes and the third is the detergent Olex process(Cio i,5) [25, 26]. The three olefin separation processes share many similarities. The first similarity between the three olefin separation processes is that each one utilizes a proprietary adsorbent whose empirical formula is represented by Cation,([(A102)),(Si02)2] [27]. The cation type imparts the desired selectivity for the particular separation. This zeolite has a three-dimensional pore structure with pores running perpendicular to each other in the x, y and z planes [28]. The second similarity between the three olefin separation processes is the use of a mixed olefin/paraffin desorbent. The specifics of each desorbent composition are discussed in their corresponding sections. The third similarity is the fact that all three utilize the standard Sorbex bed allotment that enables them to achieve product purities in excess of 98%. The following sechons review each process in detail. 

The Cio-16 Olex process produces a range of high purity C10-16 internal linear olefin product. There are five licensed units with a combined capacity exceeding 340KMTA. Cio i3 olefin product is used as a feedstock for detergent LAB, Cn i4 olefin finds use in C -is detergent alcohols and Ci5 i,5 olefin is processed into the lubricants formed from poly-internal olefins (PIO). The detergent Olex process...
