In May 2015 our organization issued the Basic Design of LPG desulfurization (mercaptan and carbonyl sulfide removal) unit for JSOC BASHNEFT (Russia, Ufa). LPG are formed on delayed coking process. Commissioning plan 2020.
6 March 2015. Licensor Private Entrepreneur Ahmadullina AG and Licensee JSOC “BASHNEFT” signed an agreement on the transfer of non-exclusive license to Licensee by Licensor under patents no. 2173330, 2110324 , 2529500. Agreement covers “the sweetening way (mercaptan removal) of LPG by regeneration of alkaline solution saturated with mercaptides in presence of KSM-X catalyst” for sweetening propane-butane fraction formed on delayed coking unit.
In the beginning of 2015 our company has successfully commissioned (mercaptan removal) DEMER-KSP technology for sweetening of kerosene fraction at «International Station for Manufacturing of Refining» W.L.L. in Bahrain with the use of KSM-X heterogeneous catalyst. The load of kerosene fraction is 40 m3/d, mercaptan sulfur content was reduced to no more than 5 ppmw. Further kerosene is used for white spirit production.
In the end of 2014 our company has successfully commissioned the sweetening (mercaptan removal) of butane fraction for LLC “LUKOIL-NNOS” with the use of KSM-X heterogeneous catalyst. The load of butane fraction increased from 16 to 23 tons/h, mercaptan sulfur content was reduced to no more than 5 ppmw, total sulfur content does not exceed 10 ppmw.
This month we published the article: “The Heterogeneous Catalyzed Oxidation in the Liquid Alkaline Medium of 2,6-di-tert-butylphenol into 3,3?,5,5?-tetra-tert-butyl-4,4?-diphenoquinone” in Research Journal of Pharmaceutical, Biological and Chemical Sciences, Volume 5, Issue 6, 2014, p.494-502, Authors: Renat Akhmadullin, Dinar Gatiyatullin, Alfiya Akhmadullina, Lev Verizhnikov, Natalya Mukmeneva, Ludmila Lapteva, Vitaly Ovchinnikov.
We will be happy if you look at our article and share your opinion.
