Removal of sulfur compounds from utility pipelined

2009-1-30 · Results show that modified activated carbons can enhance the sulfur removal capacity of activated carbon significantly and produce different selectivity for sulfur compounds. Carbons loaded with Cu and Zn had the greatest capacity for H 2 S removal; activated carbon oxidized by HNO 3 had the largest capacity for THT removal; Fe loaded carbon was more efficient for DMS removal, the most

It is also found that activated carbons impregnated with metal impurities have different selectivity for sulfur compounds. Cu and Zn loaded carbons had the highest capacity for H 2 S removal, Fe loaded carbon was more efficient for DMS removal (the most difficult S compound to remove), and carbon oxidized by HNO 3 was the best for THT removal.

Adsorptive removal of sulfur and nitrogen species

2004-6-10 · The selective removal of such sulfur species is definitely observed over the activated carbon. Unlike sulfur- and carbon-chromatograms, the distributions of nitrogen species of treated SRGO were very different from that of the feed, although the nitrogen contents were much smaller in the treated SRGOs than that of the feed SRGO.

Influence of Different Sulfur Forms on Gas-Phase

2020-7-4 · The purpose of this study is to explore the influence of different sulfur forms on vapor Hg 0 removal by SO 2 -impregnated porous carbons. After SO 2 impregnation, reductive heat treatment in N 2 and H 2 O 2 oxidation process was used to diverge the sulfur form composition in porous carbons.

Natural gas phase separation and mercury removal

Since sulfur-impregnated active carbons are vulnerable to moisture and heavier hydrocarbons, this system must be located directly after the sweetening and dehydration units. However, in such cases, due to its “high” vapor pressure Hg might be found in the offgases from the acid gas removal unit and/or the dehydrator vent gas, which gives
