Gas Phase Sulfur Adsorption Beds

The presence of sulfur in a gas stream in the form of hydrogen sulfide is well known to poison hydrogen separation membranes as well as many fuel cell stacks. Precision Combustion Inc. has developed sulfur adsorber module prototypes that can reduce the quantity of H2S in a gas stream to less than 1 PPM. Depending upon the quantity of sulfur in the fuel stream, beds can be manufactured to last from hundreds of hours through many thousands of hours without requiring regeneration or replacement.
