Description

Известен способ очистки коксового газа от сероводорода с применением поглотителей на основе карбоната натри . Однако при этом затруднена регенераци  поглотительных растворов из-за образовани  нерегенерируемых солей. Это ведет к удорожанию очистки газа.A known method of purifying coke oven gas from hydrogen sulfide using sodium carbonate-based absorbers. However, this makes it difficult to regenerate the absorption solutions due to the formation of non-regenerable salts. This leads to higher gas cleaning.

Предлагаемый способ отличаетс  тем, что в качестве поглотителей сероводорода примен ют растворы двойной соли натри  и кали  (2Ма2СОз 6Н2О К2СОз 6Н20). Это позвол ет расширить ассортимент поглотителей, улучшить услови  очистки коксового газа и снизить стоимость нронесса.The proposed method is characterized in that solutions of the double salt of sodium and potassium (2Ma2CO3 6H2O K2SO3 6H20) are used as absorbers of hydrogen sulfide. This makes it possible to expand the range of scavengers, improve the conditions for purifying coke oven gas and reduce the cost of the nroness.

При осушествлении способа коксовый газ пропускают через поглотительный раствор, состо щий из растворов двойных солей натри  и кали . Наиболее эффективным но сероемкости и степени регенерации  вл етс  поглотктель, состо щий из смеси растворов 2Ыа2СОз-6Н2О и КгСОз бНгО.During the process, the coke oven gas is passed through an absorption solution consisting of solutions of sodium and potassium double salts. The most effective capacity of sulfur content and degree of regeneration is the absorber consisting of a mixture of solutions of 2Ya2CO3-6H2O and CgSO3 bHgO.

Пример. Концентраци  поглотительного раствора 153-180 г двойной соли в литре. Пропускают через 1 л такого раствора 13618 л (10 циклов насыщени  и регенерации) 1 оксового газа (H2S 18,0- 19,0 г/;иЗ, СО2 45-48 aJM, HCN 0,8-1,2 г/л) при выдержке в течение 4-6 часов при +60° -12°; при этом не наблюдаетс  выпадени  нерастворимых солей и снижени  сероемкости. При регенерации концентраци  двойных солей уменьшаетс  незначительно.Example. The concentration of the absorption solution of 153-180 g of double salt in a liter. Through 1 l of such a solution, 13618 l (10 cycles of saturation and regeneration) of 1 oxo gas (H2S 18.0–19.0 g /; s3, CO2 45–48 aJM, HCN 0.8– 1.2 g / l) are passed when kept for 4-6 hours at + 60 ° -12 °; however, no insoluble salts precipitate and a decrease in the sulfur content. During regeneration, the concentration of double salts decreases slightly.

Предмет изобретени Subject invention

СпосЪб очистки коксового газа от сероводорода с применением поглотителей на основе карбоната натри , отличающийс  тем, что, с целью расщирени  ассортимента поглотителей, в качестве последних примен ют растворы двойной соли натри  и кали  (2Na2CO3 6Н2О К2СОз бНгО).A method of purifying coke oven gas from hydrogen sulphide using sodium carbonate based absorbers, characterized in that, in order to expand the range of absorbers, solutions of the sodium and potassium double salt (2Na2CO3 6H2O K2CO3 bNgO) are used as the latter.
