Isomerization Isomalk-2

Pentane-hexane cut Isomerization unit Isomalk-2-LIN-800 in CJSC RORC with the capacity of 800 KTA was designed under the license and design basis of PJSC SIE Neftehim. Temporary feed of the unit is IBP-70°С cut from the feed pre-treatment unit 12/1 (after a technical revamp IBP-85?С will be processed). Engineering and detailed design documentation was developed by Lengiproneftechim, LLC. The unit process flow diagram involves feed hydrotreatment section, isomerization section over SI-2 catalyst with low-octane hexanes recycle and isopentane cut recovery.

From May 13 till May 15, 2015 the test run has been conducted and the guaranteed process performances have been confirmed. The results are shown in the Test Run Certificate.

Isopentane cut with 93.0-93.5 RON and pentane-isohexane cut with 89.5-90.3 RON are produced at the unit. Stable isomerate yield is 98.6-98.8 wt. % while the guaranteed one is 97 wt. %.
