Description

Изобретение относитс  к способам извлечени  серы из газов процесса Клауса и может найти применение в химической промышленности.
Целью изобретени   вл етс  повышение степени извлечени  серы и устранение возможности забивани  аппаратуры серой.
Пример. Исходный газ, содержащий , %: HQS 92-44, вода 3,2 и кислород и следы углеводородов 3,6 под давлением 3,5, 5,6 и 84 атм., смешивают с чистым кислородом и подают в печь Клауса. Поток находитс  в со сто нии равновеси  при адиабатической температуре воспламенени . Гор чий газ, содержащий серу и воду, охлаждают в испарителе до температуры 360 С. Выход щий газ в дальнейшем охлаждаетс  в конденсаторе с получением потока воды и жидкой серы. Газ, выход щий из
конденсатора, раздел етс  на рецир- кулирующий газ и чистый газовый поток . Вода конденсируетс  с жидкой серой при давлении от 3,5 до 84 атм. Степень отделени  серы возрастает с 88,4 до 97,9%, тогда как в прототипе эта величина составл ет 65-70%,
Данные по проведению процесса выделени  серы представлены в таблице.
