Ole Jensen
The Haldor Topsoe company has for 75 years dealt with ammonia and sulfur and although Haldor Topsoe is the market leader of the world with heterogeneous catalysts for the synthesis gas industry and hydrotreating catalysts in the refining industry, Haldor Topsoe has also developed their ammonium thiosulfate (ATS) process which is characterized with having no catalyst at all.

ATS is a fertilizer product and is mainly used as an additive to conventional nitrogen containing fertilizers such as UAN and NPK fertilizers, where the ATS enhances the efficiency of these fertilizer types.

The development of the Topsoe ATS process has mainly been based on feedback from clients in the refinery industry in order to treat gases - containing a mixture of ammonia and sulfur - from their sour water treatment. In this regard, the ATS process is very competitive compared to installing a new sulfur recovery unit or to revamp an existing sulfur recovery unit in a refinery.

The ATS process has hydrogen sulfide, ammonia and sour water stripper gas as feedstock and the end product is a 60 weight-% solution of ammonium thiosulfate. The process steps to achieve the ATS product involve combustion of hydrogen sulfide into sulfur dioxide and subsequent reaction of the sulfur dioxide with ammonia to form ammonium hydrogen sulfite (AHS). The AHS reacts with the sour water stripper gas mixture resulting in the formation of ATS. The sulfur recovery is 99.95 % and the ammonia recovery is close to 100 %, which therefore also solves significant environmental issues in refineries.

The process takes place – with the exception of the combustion of hydrogen sulfide – at moderate temperatures i.e. below 200℉ and close to atmospheric pressure.
