Abstract
Przedmiotem zgłoszenia jest sposób oczyszczania gazu koksowniczego z naftalenu, amoniaku i siarkowodoru, który zwiększa efektywność pracy odsiarczalni gazu metodą amoniakalną i zmniejsza ilość nadmiarowej wody odpadowej, powstałej podczas procesu, która jest kierowana do biochemicznej oczyszczalni ścieków. Sposób polega na tym, że gaz koksowniczy poddaje się chłodzeniu wtórnemu i oczyszczaniu ze smoły i naftalenu przy użyciu medium rozpuszczjącego skąd kierowany jest do kolumnowej płuczki z sekcjami roboczymi umieszczonymi jedna nad drugą, w której zachodzi proces absorpcji amoniaku i siarkowodoru, a powstałą podczas procesu wodę zakwaszoną, po odseparowaniu cząstek stałych, poddaje się procesowi desorpcji siarkowodoru i amoniaku, która prowadzi się w kolumnowym urządzeniu odkwaszająco-odpędowym przy zastosowaniu wodorotlenku sodu, a otrzymaną podczas procesu wodę odpędzoną o zawartości amoniaku lotnego 120 ÷ 180 mg/l kieruje się do części podciśnieniowej kolumnowego urządzenia odkwaszająco-odpędowego, po czym z otrzymanej wody odpędzonej o zawartości amoniaku 60 ÷ 100 mg/l usuwa się części stałe.The subject of the application is a method of purifying coke oven gas from naphthalene, ammonia and hydrogen sulfide, which increases the efficiency of gas desulphurisation using the ammonia method and reduces the amount of excess waste water generated during the process, which is directed to the biochemical sewage treatment plant. The method consists in the fact that coke oven gas is subjected to secondary cooling and purification from tar and naphthalene using a dissolution medium, from where it is directed to a column scrubber with working sections placed one above the other, in which the process of absorption of ammonia and hydrogen sulfide takes place, and the water formed during the process acidified, after separation of solid particles, is subjected to the process of desorption of hydrogen sulfide and ammonia, which is carried out in a deacidification and stripping device using sodium hydroxide, and the stripped water obtained during the process with volatile ammonia 120-180 mg / l is directed to the vacuum part column deacidification and stripping device, after which solids are removed from the stripped water with ammonia 60 ÷ 100 mg / l.
