Iron Sponge

{0 Comments}

The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams. This process is applied to gases with low H2S concentrations (300 ppm) operating at low to moderate pressures (50-500 psig). Carbon dioxide is not removed by this process. The reaction of H2S and ferric oxide produces water and …

Solid Bed Absorption

{0 Comments}

A fixed bed of solid particles can be used to remove acid gases either through chemical reactions or ionic bonding. Typically, in solid bed absorption processes the gas stream must flow through a fixed bed of solid particles that remove the acid gases and hold them in the bed. When the bed is saturated with …

Gas Sweetening Processes

{0 Comments}

Numerous processes have been developed for gas sweetening based on a variety of chemical and physical principles. These processes can be categorized by the principles used in the process to separate the acid gas and the natural gases as follows: The list, although not complete, does represent many of the commonly available commercial processes. New …
