Abstract

본 발명은 황제거및 회수기술로 널리 알려진 클라우스 공정의 테일가스 처리공정에 관한 것이다. 종래의 클라우스 공정 테일가스 처리공정은 설치비용 및 운전비용이 많이 들 뿐만 아니라 어떠한 공정이라도 SOx를 완전제거하는 것이 어려우므로 결국 소각로를 통하여 SOx를 배출하게 된다. 본 발명은 클라우스 공정의 테일가스를 소각하지 않고, 수소화 촉매반응기에서 수소화촉매를 사용하여 175-325℃의 반응온도에서 테일가스중의 황및 황화합물을 황화수소로 전환시킨후 클라우스 공정의 황화수소 포집과정으로 재순환시킴으로써 SOx를 대기중으로 배출시키지 않는, 클라우스 공정의 테일가스 처리공정을 제공한다. 본공정에서, 수소화 촉매로는 주로 전이금속과 VB, VIB족 금속들을 그대로 사용하거나 또는 알루미나, 실리카, 알루미나-실리카 같은 담체에 담지시켜 사용한다.The present invention relates to a tail gas treatment process of the Klaus process, which is widely known for sulfur removal and recovery techniques. The conventional Klaus tail gas treatment process is expensive to install and run, and it is difficult to completely remove SOx in any process, and eventually SOx is discharged through the incinerator. The present invention converts the sulfur and sulfur compounds in the tail gas into hydrogen sulfide at a reaction temperature of 175-325 ° C. using a hydrogenation catalyst in a hydrogenation catalytic reactor without burning tail gas of the Klaus process, and then collects hydrogen sulfide in the Klaus process. The recycle provides a tail gas treatment process for the Klaus process that does not release SOx into the atmosphere. In this process, the hydrogenation catalyst is mainly used as the transition metal and VB, Group VIB metal as it is or supported on a carrier such as alumina, silica, alumina-silica.

제1도는 본 발명에 따른, 클라우스 공정의 테일가스 처리공정도.1 is a tail gas treatment process of the Klaus process according to the present invention.

Claims (1)

황미스트및 황화합물을 함유한 클라우스 공정의 테일가스를 처리함에 있어서, 테일가스를 소각하지 않고, 수소화촉매반응기에서 수소화 촉매를 사용하여 250-325℃의 반응온도에서 테일가스중의 황화합물을 황화수소로 전환시킨 후 클라우스 공정의 황화수소 포집과정으로 재순환시킴으로써 SOx를 대기중으로 배출시키지 않는 것을 특징으로 하는 클라우스 공정의 테일가스 처리공정.In treating the tail gas of the Klaus process containing sulfur mist and sulfur compounds, the sulfur compounds in the tail gas are converted to hydrogen sulfide at a reaction temperature of 250-325 ° C. using a hydrogenation catalyst in a hydrogenation catalyst reactor without incineration of the tail gas. The tail gas treatment process of the Klaus process, characterized in that the SOx is not discharged into the atmosphere by recycling to the hydrogen sulfide capture process of the Klaus process. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
