очистки газа от сероводорода его жид- кофазным окислением в элементарную серу.gas purification from hydrogen sulfide by its liquid-phase oxidation to elemental sulfur.
Целью изобретени вл етс повышение степени очистки и упрощение процесса.The aim of the invention is to increase the degree of purification and simplify the process.
Пример 1. 1700 нм /ч отход щего газа производства серы по спо- Q ванади . Поэтому дл достижени той собу Клауса, содержащего после же степени очистки, что и в примереExample 1. 1700 nm / h of sulfur production off-gas by the method of Q-vanadium. Therefore, to achieve that Claus containing, after the same purity as in the example
ный ванадий в виде комплекса 1,5; роданит натри 20; 2,7-антрахинонди- сульфокислота 50. При этом степень очистки газа от сероводорода резко снижаетс , что обусловлено недостаточной быстротой протекани процесса обратного окислени восстановленногny vanadium in the form of a complex of 1.5; Rodanite sodium 20; 2.7-anthraquinone di-sulfonic acid 50. At the same time, the degree of gas purification from hydrogen sulphide decreases sharply due to the insufficient speed of the process of the reverse oxidation of reduced

Процесс провод т в течение 30 мин. При этом в течение всего процесса степень очистки отход щего газа от сероводорода составл ет более 99,9%.conventional hydrogenation, vol.%: hydrogen sulfide 0.52; sulfur dioxide, 002; carbonyl sulfide 0.001; carbon disulfide, 0.002, countercurrent, is treated in a packed wash column 58 HMVM npOMKBHoA of water containing, g / l: sodium carbonate 20; pivalent vanadium 1.5; sodium rodanite 20 (to prevent the formation of thiosulfate); diethanolamine 50. The process is carried out for 30 minutes. Moreover, throughout the entire process, the degree of purification of the off-gas from hydrogen sulfide is more than 99.9%.
Пример 2 (известный). Повтор ют пример 1 с той разницей, что используют промывную воду, содержащую.Example 2 (known). Example 1 is repeated with the difference that the wash water containing is used.

При этом степень очистки газа от сероводорода резко снижаетс , что обусловлено недостаточной быстротой протекани процесса обратного окислени восстановленногоny vanadium in the form of a complex of 1.5; Rodanite sodium 20; 2.7-anthraquinone di-sulfonic acid 50. At the same time, the degree of gas purification from hydrogen sulphide decreases sharply due to the insufficient speed of the process of the reverse oxidation of reduced
1, концентрацию п тивалентного ванади следует повысить на 46,6%, т.е. до 2,2 г/л.1, the concentration of pyvalent vanadium should be increased by 46.6%, i.e. up to 2.2 g / l.
