Sulphur Recovery
Leverage sulphur recovery technologies to ensure your gas products are on-spec. Combining owner/operator expertise with in-depth knowledge of upstream and downstream processes, we deliver high-quality, fit-for-purpose designs, comprehensive training, and effective troubleshooting.
Upstream & Downstream Sulphur 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 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鈥 sulphur recovery technology offers high flexibility and maximises reliability.
Experienced Petroleum Consultants backed by State-of-the-Art Sulphur Recovery Technology

Shell Catalysts & Technologies鈥 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鈥檚 crucial that refineries optimise their yield鈥檚 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.
Sulphur Recovery Unit Frequently Asked Questions
Many gas reserves and crude oils contain high levels of sulphur compounds, and it is important to ensure that these do not leave the refinery or gas plant as harmful emissions. A range of sulphur recovery unit technologies is available that can address the increasing demand for deep sulphur removal and meeting environmental standards.
Sulphur Recovery Solutions

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.
