Upstream & Downstream Sulfur Recovery Process Technologies

Many gas reserves are richer in hydrogen sulphide (H2S) and, therefore, sulphur. At the same time, tighter standards mean gas plants need to achieve deeper levels of sulphur removal in order to meet their environmental mandate. Sulphur recovery efficiencies of over 99.9% are being specified on some projects.

In order to achieve this, Shell Catalysts & Technologies offers a portfolio of sulphur recovery technologies catering for the full range of sulphur removal capacities that can be integrated parts of complex gas cleaning line-ups to provide safe, reliable and easy-to-operate complex systems, and that are economically attractive and environmentally responsible.

Customers are looking for solutions that will meet the required emission standards and minimise capital and operating costs. Simplified process line-ups can help to reduce complexity and keep costs down. Additionally, Shell Catalysts & Technologies’ sulphur recovery technology offers high flexibility and maximises reliability.

Experienced Petroleum Consultants backed by State-of-the-Art Sulphur Recovery Technology

Shell Catalysts & Technologies’ reliable and robust operations with Claus, SCOT, sulphur degassing and THIOPAQ O&G sulphur recovery technologies secure gas production and ensure refiners adhere to stringent sulphur dioxide (SO2) standards. With IMO2020 around the corner, it’s crucial that refineries optimise their yield’s sulphur composition. As with all Shell Catalysts & Technologies offerings, as petroleum consultants, we take a holistic view of your current technology and operations before making any recommendations.

We offer a wide range of cutting edge technology which is cost-effective, compliant, and built for the future. Let us implement solutions which meet environmental standards, sustainability concerns, and move the needle for refiners.

H₂S to Sulphur Conversion

Shell Catalysts & Technologies’ Thiopaq O&G process is a biological gas desulphurisation process that integrates gas purification with sulphur recovery. 

Claus Off-Gas Treating (SCOT) Process

Refineries have lowered operating costs and extended cycle lengths by installing our technologies and catalysts in Claus tail-gas treating units.

Sulphur Degassing

Our sulphur degassing process substantially cuts the hydrogen sulphide and hydrogen polysulphide in Claus liquid sulphur in conventional sulphur pits.
