Abstract
Removal of hydrogen sulfide from crude oil is required for delivery of commercial-quality oil to main pipeline system as per GOST R 51858-2002 “Crude petroleum. General specifications". Nowadays several technologies for reduction of hydrogen sulfide content to the required level are applied. These are technologies based on application of hydrogen sulfide chemical scavengers, technology of liquid-phase oxidation of hydrogen sulfide in presence of air and hydrogen sulfide desorption in stripping columns.
Direct oxidation of hydrogen sulfide in crude oil with atmospheric oxygen in presence of catalyst complex has an indisputable economic advantage over application of chemical scavengers, and also compared to stripping method in case the first group of oil quality is required. However, substantial capital investments required for construction of such facilities encouraged the search for new approaches to reduce process costs. Oxygen-assisted catalytic process for removal of hydrogen sulfide combined with oil transport was developed and optimal concentration of oxygen in oxygen-air mixture was determined. Research for substantiation of fire and explosion safety of the technology during mixing of crude oil and process oxygen was conducted.
