Cynara
H2S and CO2 separation membranes
Separate acid gases from produced natural gas without chemicals.
SELECT S H2S removal adsorbent
Used in H2S scrubbers for hydrogen sulfide removal from natural gas and liquid streams, syngas, and other industrial applications
Overview
Enhanced action, flexibility, and minimal human intervention
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.
Highest performance
Longer bed life and fewer changeouts; can reduce H2S to <0.1 ppmv
Fastest reaction time
Leading to smaller system sizes and lower capex
Greater reliability
Proven product delivered with a performance warranty
Lower impact
Typical disposal via metal recovery, reducing landfill waste
Applications
Leading mixed-metal-oxide products used in many different industries
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.

Benefits
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 SLB representative can assist you with this process.
