TOTAL ISOMERIZATION PROCESS OF PARAFFINS Overall Reaction... 

Over 25 plants are operating the total isomerization process (TIP) and this number is growing continuously. Many millions of tons of isomerized paraffins are produced annually by this process. 

The normal isoparaffin seperation process used most often is the Union Catbide IsoSiv process. Units with fsed capacities of up to 3600 metric considay have been built. In tha mid-1970 s the Hysomer paraffin-isomarizaiion process, developed by Shell Research B.V.. was combined with the IsoSiv process in such a way tbet normal paraffins are nearly completely isomerized.131 The combination is called the Total Isomerization Process (TIP) and is shown schematically in Fig. 12,5-7. Product hom a TIP unit has a Rerearch OctHne Number of 88-92, compared to 79-82 for the product from a Hysomar unit alone. 

Total Isomerization Also called TIP. An integrated process which combines light paraffin isomerization, using a zeolite catalyst, with the IsoSiv process, which separates the unconverted normal paraffins so that they can be returned to the reactor. Developed by Union Carbide Corporation and now licensed by UOP. The first plant was operated in Japan in 1975 by 1992, more than 25 units had been licensed.
