TENDENCY OF ISOMERIZATION PROCESS DEVELOPMENT （4）
6. THE DEVELOPMENT OF ISOMERIZATION PROCESS
IN RUSSIA AND IN THE WORLD
UOP is the leader in licensing of isomerization technology; more than 220 units in the world are operating by its technology currently. More than 120 units of them are working by Penex process; more than 60 units are working on zeolite catalysts (TIP process is also referred to them) and more than 10 units are operating by Par-Isom technology. More than 30 units in the world are operating by Axens license, and more than 20 units are working on the base of CKS ISOM process of Sьd-Chemie company.
Izomalk-2 processes of JSC “NPP Neftehim” are operating not only in Russia; there is one unit in Ukraine and one unit in Rumania .
Let’s refer to gasoline pool composition and to isomerizate contribution in it in Russia, Europe and USA, in order to understand the tendency of development of isomerization process in our country (Figure 13) [7,21].
Analysis of isomerization process development has shown its swiftly increasing of competitive ability compared with other processes, which are directed to gasoline components production. At that, the schemes of projected and reconstructed processes are provided predominately with recycle of low-octane pentanes and hexanes. It is connected with necessity of production of automotive gasoline, which corresponds ton tougher standards.
It should be noted, that preference is given to the processes on sulfated zirconium oxides. In Russia the preference is essentially given to the process on СИ-2 catalyst of domestic manufacturer. It is explained by operational characteristics of this type of catalyst, at which it isn’t inferior to the foreign analogs.
