Description
Изобретение относитс к очистке газов от сероводорода и может быть использовано в химической промышленности.The invention relates to the purification of gases from hydrogen sulfide and can be used in the chemical industry.
Целью изобретени вл етс повышение эффективности за счет увеличени скорости процесса регенерации и повышени выхода серы.The aim of the invention is to increase efficiency by increasing the speed of the regeneration process and increasing the sulfur yield.
Пример 1. В барботажную колонну емкостью 250 мл ввод т раствор соды концентрации 10 г/л, раствор ЭДТА концентрации 0,05 моль/л соли Fe нри ее соотношении к ЭДТА 1:1 и ТЛОБ в количестве 5 мл до концентрации триацетоок- сибензолом 2,5Х моль/л. В раствор подают сероводород до концентрации в растворе 1,5Х моль/л и воздух с расходом 30 л/ч.. В процессе опыта рН раствора поддерExample 1. A soda solution with a concentration of 10 g / l, a solution of EDTA with a concentration of 0.05 mol / l of Fe salt and its ratio to 1: 1 EDTA and TLOB in an amount of 5 ml are added to a 250 ml bubble column to a concentration of triacetoxybenzene 2 , 5 mol / l. Hydrogen sulfide is fed to the solution to a concentration in the solution of 1.5 x mol / l and air with a flow rate of 30 l / h. During the test, the pH of the solution is supported
живают в пределах 8,5-10,5. Скорость окислени достигает 4,2 моль/л/мин, а выход серы 94%.live in the range of 8.5-10.5. The oxidation rate reaches 4.2 mol / l / min, and the sulfur yield is 94%.
Пример 2. Добавлени ТАОБ (триацето- оксибензола) не производ т. Все другие услови опыта аналогичны. Скорость окислени достигает 3,3 моль/л/.мин, а выход серы 88,9%.Example 2. TAOB (triacetoxybenzene) was not added. All other test conditions are similar. The oxidation rate reaches 3.3 mol / l / .min and the sulfur yield is 88.9%.
Провод т р д аналогичных опытов при различпой концентрации ТАОБ, опреде;1 скорость окислени и выход серы. Результаты опытов показывают, что опти- .мальной вл етс концентраци катализатора , равна (0,2-10)-10 моль/л. При добавлении катализатора в таком количестве получаютс результаты по выходу серы на уровне примера 1.A series of similar experiments were carried out at a different TAOB concentration, determined; 1, the oxidation rate and the yield of sulfur. The results of the experiments show that the optimum concentration of the catalyst is (0.2-10) -10 mol / l. Adding a catalyst in such an amount gives results on the sulfur yield at the level of Example 1.
