Abstract

Studies aimed at improving the efficiency of the field preparation of hydrogen sulfide and mercaptan-containing oil are especially relevant in connection with the tightening of regulatory requirements for quality and safety indicators of commercial oil. The Technical Regulation (TR) of the Eurasian Economic Union TR 045/2017 -On the safety of oil prepared for transportation and (or) use- establishes uniform requirements for the safety indicators of oil delivered through trunk pipelines, as well as used as a raw material in oil refineries or petrochemical plants: hydrogen sulfide content - no more than 20 ppm, the total content of methyl and ethyl mercaptans - no more than 40 ppm. The proposed technology for cleaning oil stripping gas from hydrogen sulfide and mercaptans meets the requirements of modern oil safety standards and can be implemented in the format of a modular-block plant. It is possible to adapt the plant to operating conditions, modify and complete the plant, taking into account the content of light hydrocarbons and hydrogen sulfide in the oil being purified and mercaptans. The selected technological version of the installation scheme is the most rational for the construction of the installation according to the block-modular principle (for installation of the installation on site from blocks of various functional purposes).
