Summary:Availability of extra cold solvent in an existing solvent dewaxing unit can increase dewaxed oil production by debottlenecking refrigeration, solvent recovery and filtration sections of the unit. Mobil did just this by adding an innovative membrane process, called Max-Dewax, to its Beaumont, Texas, refinery. The process selectively recovers cold solvent from the filter in an SDU. With this application, the firm developed the first large-scale commercial application of organic membranes for liquid-liquid hydrocarbons separation in the refining or petrochemical area. Adding this process to an existing unit costs less than one-third the capital cost of conventional unit expansion. Therefore, a refiner can use Max-Dewax inexpensively to increase lube and wax production.
