N-olefins play key role in the production of detergent alcohols
Detergent range n-olefins are the primary raw materials used to produce detergent alcohols (C12–C16). As a variation to the processes that produces normal paraffins and LAB, the UOP Molex™, UOP Pacol™, and UOP DeFine™ processes can be combined with the UOP Olex™ process for the production of high purity linear internal n-Olefins.
Kerosene fractionation is the first step in feed preparation, tailoring the feedstock to the desired carbon number range of the resultant n-Olefin product. Contaminant removal (sulfur, nitrogen, and oxygenates) is accomplished in the UOP Distillate Unionfining™ process, providing high quality feedstock for optimum Molex unit performance.
The Molex process is a liquid-state separation of normal paraffins from branched and cyclic components using UOP Sorbex technology. It operates in the liquid phase and simulates a moving adsorbent bed in a fixed-bed system by use of a proprietary multi-port rotary valve. The almost “attention-free” process technology and its low operating costs make it the most attractive n-Paraffin separation process commercially available. Since its introduction to the marketplace in the 1960′s, more than 35 Molex units have been licensed.
n-Paraffin Conversion to n-Olefins
Minimal loss of feedstock to byproducts makes the Pacol process the most economical paraffin dehydrogenation technology available. During the process, normal paraffins are dehydrogenated to their corresponding mono-olefins using UOP’s highly active and selective DeH series of catalysts. The dehydrogenation is achieved under mild operating conditions. The Pacol process was first commercialized in the 1960′s and more than 40 units have been licensed.
The DeFine process improves overall olefin yields by selectively hydrogenating di-olefins produced in the Pacol process into their corresponding mono-olefin. The DeFine process was first commercialized in the 1980′s and more than over 35 units have been licensed.
The Olex process is a liquid-state separation of normal olefins from normal paraffins using UOP Sorbex technology. It operates in the liquid phase and simulates a moving adsorbent bed in a fixed-bed system by use of a proprietary multi-port rotary valve. The almost “attention-free” process technology and its low operating costs make it the most attractive n-Olefin separation process commercially available. Since its introduction to the marketplace in the 1960′s more than five Olex units have been licensed.
