FIELD: gas-oil-producing and processing industry; methods and devices of purification of the gas containing hydrogen sulfide. ^ SUBSTANCE: the group of inventions is pertaining to the field of purification of the gas containing hydrogen sulfide and may be used in gas-oil-producing and processing industry. The method providing for purification of the gas containing hydrogen sulfide with extraction of sulfur by oxidizing the gas includes its contacting with the activated charcoal with the subsequent regeneration of the latter. Before contacting with the charcoal the oxidization is conducted by injecting of the dispersed oxygen saturated water into the purified gas, and the contacting with the charcoal is exercised for a short time. At that the activated charcoal is located on the rotating surface. The product of oxidation representing the suspension made out of the condensate, water and the elemental sulfur is subjected to flotation, and a part of the purified from hydrogen sulfide gas preheated and use in the process of flotation and regeneration. The installation for purification of the gas includes the block of oxidation, the block of saturation of the water with oxygen, the injector, on the outlet of which there is the screen with the filtering surface, the block of flotation, on the outlet of which there is the block of compaction of the elemental sulfur connected with the block of smelting, the accumulator of the liquid. The screen filtering surface has the layer of the activated charcoal and is made with the capability of rotation and regeneration by the heated gas of the back blowing. The block of saturation of water with oxygen is connected to an inlet of the injector, and the accumulator of the liquid is made with the capability of the three-phase separation into the water, the gaseous condensate and the gas degased from the liquid. The inventions ensure the increased service life of the installation, improvement of the quality of purification, the possibility to separate the condensate in the process of the purification and utilization of the products of the purification. ^ EFFECT: the inventions ensure the increased service life of the installation, improvement of the quality of purification, the possibility to separate the condensate in the process of the purification and utilization of the products of the purification. ^ 15 cl, 1 dwg |
