General Description – SweetGas-DG is a high capacity, nonhazardous granular media made from 98% natural and
recycled products. It is comprised of a high porosity mixed iron- oxide tightly bound on a stable hydroscopic inert base.
The media is useful for H2S and light mercaptan control in air and a variety of gasses. This high-capacity media works
without oxygen; however a minimum molar ratio, O2 to H2S, of one (1) or more will increase reaction speed and improve
sulfur removal capacity.
Its unique formulation allows reliable performance in air or gas with 50% or more relative
humidity without the need for added water.
Product Features
- High capacity sulfur removal, up to 15% by weight for anaerobic (11 lbs sulfur per cu.ft.) and 30% by weight for aerobic conditions (22.5 lbs sulfur per cu. ft.)
- Cost-effective, reliable low0level hydrogen sulfide removal with starting outlet levels at non-detect and slowly rising to the desired maximum outlet concentration.
- Reaction products are primarily basic sulfur and some stable iron sulfides
- Does not require full water saturation for reliable performance
- High particle strength and low dust content
- Low and stable pressure drop from beginning to end of run
- Presence of liquid water or hydrocarbons does not interfere with media efficacy
- Can be returned to manufacturer for re-processing or meets US and California requirements for non-hazardous disposal (assuming no process contamination of the media)
