Abstract

본 발명은 원유의 중량 분획을 진공 증류할 때 발생하는 비응축성 가스 산물을 탈유황 처리하는 장치 및 방법에 관한 것이다. 탈유황처리할 초기 가스 혼합물(8)은 황화 수소를 포함하는 비응축성 가스이다. 가스-액체 접촉 칼럼(2)은 충전 물질 베드를 함유하는 제1 및 제2섹션(3,4)을 포함하고 있으며, 상기 충전 물질은 구조화된 것이거나 불규칙적인 충진재를 일수 있다. 상기 베드는 하부에서 이의 습윤화를 촉진하지만, 칼럼을 통한 가스에서의 압력 저하는 최소화하는 관주 장치(18)에 의하여 지지된다. 초기 가스 혼합물을 건조시킨 후, 칼럼의 제1섹션으로 도입(14)한다. 초기 가스 혼합물에 존재하는 황화수소와 반응하기 위하여 필요한 화학 양론적 분량의 새로운 암모니아 용액(9)도 상기 칼럼의 제1섹션으로 도입된다. 마지막으로, 칼럼의 제1섹션은 제2섹션을 통과하여 제1섹션으로 들어오는 제2암모니아 용액을 수용한다. 칼럼의 제1섹션에서, 초기 가스 혼합물, 새로운 암모니아 용액 및 상기 칼럼의 제1섹은 제2섹션을 통과하여 제1섹션으로 들어오는 제2암모니아 용액이 접촉하여 가스류를 방출하고, 이는 칼럼의 제2섹션으로 들어간다. 방출된 가스류는 제1섹션에서 반응하지 않고 나온 모든 암모니아와 황화수소를 포함한다. 이들은 화학량론적 양만큼 존재한다. 제2섹션에서, 방출된 가스류는 물과 접촉하여, 반응하지 않은 암모니아와 황화수소를 포획하여 제2암모니아 용액을 형성한다. 제2암모니아 용액은 포획된 화학양론적 암모니아와 황화수소를 제1섹션으로 운반한다. 탈유황 처리된 가스는 칼럼의 제2섹션으로부터 회수된다.The present invention relates to an apparatus and a method for desulfurizing a non-condensable gas product which occurs upon vacuum distillation of a weight fraction of crude oil. The initial gas mixture 8 to be degummed is a non-condensable gas containing hydrogen sulfide. The gas-liquid contact column 2 comprises first and second sections (3,4) containing a bed of filler material, which may be structured or irregular fillers. The bed is supported by a conduit device 18 which promotes its wetting in the bottom, but minimizes the pressure drop in the gas through the column. The initial gas mixture is dried and then introduced (14) into the first section of the column. A new stoichiometric amount of ammonia solution 9 required to react with the hydrogen sulfide present in the initial gas mixture is also introduced into the first section of the column. Finally, the first section of the column receives the second ammonia solution through the second section and into the first section. In the first section of the column, the initial gas mixture, the fresh ammonia solution and the first sector of the column pass through the second section and contact the second ammonia solution entering the first section to release the gas stream, Go into two sections. The discharged gas stream contains all the ammonia and hydrogen sulphide that did not react in the first section. They exist by stoichiometric amount. In the second section, the released gas stream is contacted with water to capture unreacted ammonia and hydrogen sulphide to form a second ammonia solution. The second ammonia solution conveys captured stoichiometric ammonia and hydrogen sulphide to the first section. The desulfurized gas is recovered from the second section of the column.
