Universal Oil Products Company

The characterization factor KyQp was introduced by research personnel from the Universal Oil Products Company. 

Njlene Separation. -Xylene is separated from mixed xylenes and ethylbenzene by means of the Parex process (Universal Oil Products Company). A proprietary adsorbent and process cycle are employed in a simulated moving-bed system. High purity -xylene is produced.

The Universal Oil Products Company found in its research laboratories that hydrofluoric acid offers advantages over sulfuric acid. These include the advantages that hydrofluoric acid was able to operate without the aid of refrigeration and also that hydrofluoric acid could easily be regenerated for the removal of polymers and reused, while it is necessary to ship sulfuric acid back to an acid-manufacturing plant to be made into new acid. 

A widely used commercial catalyst is the extruded pellet type of calcined phosphoric acid and kieselguhr developed by Universal Oil Products Company. It is the most active of the catalysts used in polymerization and has the greatest active surface area. 

Two types of polymerization units are designed by Universal Oil Products Company. The U.O.P. Reactor-type unit contains the catalyst in tubes which are surrounded by water in a jacket for the purpose of removing the heat liberated by the exothermic polymerization reaction. The steam generated in the water jacket normally is used to preheat the feed. A feed-to-products heat exchanger furnishes the remaining heat requirements. Conventional depropanizer and debutanizer columns are used to fractionate the product. Figure 3 shows a flow diagram of a reactor type of polymerization unit. 

The solubility measurements were made using the UOP Method 614-68 entitled Heptane-Insoluble Matter in Petroleum Oils Using a Membrane Filter Heptane-Insoluble Method with Ultrasonic Agitation. The method description was kindly supplied by the Universal Oil Products Company.

In the fluid-catalyst process, finely divided catalyst powder is continuously circulated from reactor to regenerator and back again without mechanical means. The fluid process was originated by the Standard Oil Development Company, the research organization of the Standard Oil Company of New Jersey, in collaboration with The M. W. Kellogg Company and Standard Oil Company (Indiana). Other companies participating in the development were Anglo-Iranian Oil Company, Ltd., Shell Oil Company, The Texas Company, and Universal Oil Products Company. This process was first announced in 1941 (48).
