A Plant of Gasoline Fractions Isomerization “Isomalk-2” was commissioned at YANOS


On October 30th an opening ceremony of  a new plant of Gasoline Fractions C5-C6 Isomerization "Isomalk-2" designed for obtaining high octane components of blended gasolines without sulfur admixtures and aromatic hydrocarbons (isopentane fraction, light and heavy isomerizate) took place at JSC "Slavneft-YANOS".

 The plant consists of three main sections:  hydrotreating, fractionation and isomerization. "Isomalk-2" plant crude throughput is 600,8 thous. tonnes per year.

Commissioning of this plant shall enable YANOS considerably increase production of high quality gasolines having improved consuming and ecological properties. Implementation of this project will promote YANOS to complete a changeover for production of exclusively high quality gasolines meeting requirements of Euro-4 and Euro-5 in the near future.


Process flowsheet used at the plant was developed by JSC "NPP "Neftekhim" (Krasnodar, RF), engineering was done by JSC "Neftehimproject" (St. Petersburg). A General Subcontractor of consruction and installation works was JSC "SK SNS". The most of the equipment and materials used during "Isomalk-2"  construction was produced in Russia.


Financing of this project made 4,5 billion rubl.


Construction of  the plant "Isomalk-2"  was implemented with the framework of the modernization and technical upgrade of JSC "Slavneft-YANOS" capacity. In 2011 YANOS is also planning to finalize construction of FCC gasoline hydrotreatment unit.
