Leading mixed-metal-oxide products used in many different industries

Fast-reacting SELECT S hydrogen sulfide removal adsorbents are engineered mixed-metal-oxide chemistries using enhanced porosity control for improved activity. They facilitate greater flexibility in system design, and formulations are available for treatment of both dry and water-saturated gas. These proven products provide reliable and predictable performance, while the absence of moving parts means little-to-no operator attention is required.

Our adsorbents are used on floating production, storage, and offloading (FPSO) facilities and offshore platforms; in gas processing and petrochemical plants, refineries, and gas storage facilities; for treating biogas, food-grade CO2, fuel gas, hydrogen, landfill gas, and syngas; for odor control, vent gas treatment, and wastewater treatment; and more.

Cost-effective, efficient, and sustainable operation

The sour feed flows through the adsorbent bed, where the H2S chemically reacts with the media. Product consumption depends only on the amount of H2S that passes through, economically matching the need for H2S removal with variations in system flow conditions. If these parameters are constant, system performance is very predictable.

A single vessel can be used, but a lead-lag configuration provides the greatest operating flexibility, enabling continuous production while media is replaced. The flexibility of the treatment process enables the system to adapt to changes in operating conditions, often without additional capital equipment or retrofitting.

All our adsorbents are nonpyrophoric and straightforward to handle in both unreacted and ready-for-disposal forms. Disposal routes are well established and your Schlumberger representative can assist you with this process.

Superior quality control and customized support

Products are manufactured to stringent quality specifications. Customized software modeling and performance predictability enable optimal system design and operation for each application, supported by highly trained personnel at every stage. Our tailored support ranges from basic media provision through to a fully engineered technical solution comprising system design, media supply, detailed engineering, fabrication package, equipment supply, and spent-media handling.
