Transfer of sulfur into molten slag from CO-CO2-SO2 gas mixture.

Zeolite screening for the separation of gas mixtures containing SO2, CO2 and CO.

We used a combination of experiments and molecular simulations to investigate at the molecular level the effects of zeolite structure on the adsorption and diffusion of sulfur dioxide, carbon dioxide and carbon monoxide as well as separation processes of their mixtures. Our study involved different zeolite topologies and revealed numerous structure-property trends depending on the temperature a...

Ceria-based catalysts for the recovery of elemental sulfur from SO2-laden gas streams

The catalytic reduction of SO2 to elemental sulfur by CO or CH4 over ceria-based catalysts under demanding operating conditions is reported in this paper. Cuor Ni-containing ceria catalysts have been shown before to be highly active and selective for SO2 reduction by CO in dry gas streams or in the presence of low amounts of H2O. In this work, the activity/selectivity of 10 at.%La-doped ceria, ...

Measurement of Mass Transfer Coefficients of Natural Gas Mixture during Gas Hydrate Formation

In this study, mass transfer coefficients (MTC’s) of natural gas components during hydrate formation are reported. This work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. Several experiments were conducted on a mixture of natural gas at different pressures and temperatures and the consumed gas was monitored an...

estimation of cost curve to control sulfur dioxide gas (so2) emissions from sarcheshmeh copper complex

introduction sarcheshmeh copper mine is regarded as the second largest copper deposit in the world. this is one of the largest industrial-mining complexes in the world and the largest producer of copper in iran. this complex plays an important role in iran’s economy. in 2012, this complex created employment for about 8000 people in iran and produced 203065 tons of copper cathodes. however, high...

Reaction of Sulfur Dioxide (so2) with Reversible Ionic Liquids (revils) for Carbon Dioxide (co2) Capture
