To develop an effective method for removing sulfur from spent refining slag at high temperature, the slag was treated in argon atmosphere using desulfurization ash as desulfurization reagent. Experimental results revealed that at 1773 K, molar ratio of CaS to CaSO4 + CaSO3 of 3:1, and reaction time of 2 hours, sulfur removal efficiency reached …

Abstract. The removal of sulfur compounds and siloxanes, which are major impurities in the biogas produced from the anaerobic digestion of sewage sludge, was studied using a bench-scale adsorptive gas purification experimental setup. The main impurities are hydrogen sulfide (H 2 S), carbonyl sulfide (COS), carbon disulfide (CS2 ...

In this study, sulfur (S) removal and transformation in five batch constructed wetlands (CWs) treating secondary effluent were investigated. The results showed that the presence of the plant cattail ( Typha latifolia ) had little effect on sulfate removal, while the carbon-rich litter it generated greatly improved sulfate removal, but with ...

Sulfur and Arsine Removal Innovative Absorbent Technology Manufactured in Alvin, TX Zeolitic Sulfur & Arsine Removal CLS has been removing complex S compounds from hydrogen/hydrocarbon streams for over 15 years specializing in removal of mercaptanic, thiophenic and benzothiophenic species. The net effect of zeolitic sulfur guards from …

The reaction mechanism of catalytic removal of organic sulfur over various catalysts was summarized and analyzed. Specific surface area, hydroxyl, metal components and surface functional groups of catalysts affect removal efficiency. Organic sulfur can be converted to CH 4, CH 3 OH and CH 3 SH for resource utilization.

Sulfur Removal System. $195.00 USD. Tax included. 4 interest-free installments, or from $17.60/mo with. Check your purchasing power. The SRS unit sprays water from the storage tank back into the well casing through a special nozzle. This aerates the water to release the sulfur gas, and vents it out of the system at the well - making great ...

The Sulfur Removal System was originally developed for Brays Island, an exclusive hunting resort in Beaufort County, South Carolina (which is also home to Parris Island and Hilton Head Island). The resort was once a 5000 acre hog farm that was divided into one acre lots and sold for $500,000 each. Many wealthy people f

In the case of a feedstock with low sulfur content, removal of sulfur can be achieved by absorption processes, e.g., absorption on a zinc oxide catalyst bed. In the …

Liquid redox chemistry has been employed for sulfur removal and recovery applications since the 1950's. The first process was the Stretford process, which was used commercially in the United Kingdom in the 1960's as a replacement for the iron sponge process in the treatment of sour town gas. The Stretford process has been joined in the United ...

This paper proposes a novel approach to sulfur removal by adding aluminum in the bayer process of high-sulfur bauxite. The effects of aluminum dosage on the concentrations of different valence sulfur in sodium aluminate solution were investigated at length to find that high-valence sulfur (S 2 O 3 2−, SO 3 2−, SO 4 2−) concentration in …

The removal efficiencies for the Basra oil were superior to those for the Iranian oil, with 90%, 79%, and 63% of V, Ni, and sulfur being removed, respectively (Table 7 and Fig. 17).
