Oxidational-catalytic DMC-1MA process for deep treatment of heavy oils for hydrogen sulfide and mercaptans

Authors: A.F. Vildanov, I.R. Aslyamov, I.K. Khrushcheva, N.R. Ayupova, A.M. Mazgarov (Volga Research Institute of Hydrocarbon Feed JS, RF, Kazan), A.K. Safiullina (Kazan National Research Technological University, RF, Kazan)

Key words: oil, hydrogen sulfide, mercaptans, ammonia-catalytic oxidation.

Pilot-commercial tests of modified DMC-1MA plant were carried out for the aim of deep oil treating to hydrogen sulfide content below 10 ppm. Disadvantages of using chemical reagents and purging with a hydrocarbon gas as compared to ammonia-catalytic oxidational method are shown.
