Scavenging and tailgas process

A process for removing sulfur dioxide from a hydrogen sulfide-containing gas utilizes a bubble tower and overcomes process control difficulties associated with known processes. Solvent is fed to the bubble tower, loaded with sulfur dioxide and maintained at desired temperature and pressure. Hydrogen...

More Information
Summary:A process for removing sulfur dioxide from a hydrogen sulfide-containing gas utilizes a bubble tower and overcomes process control difficulties associated with known processes. Solvent is fed to the bubble tower, loaded with sulfur dioxide and maintained at desired temperature and pressure. Hydrogen sulfide-containing gas is bubbled through the solvent, causing chemical reaction between the sulfur dioxide and hydrogen sulfide to yield water and elemental sulfur. Elemental sulfur is collected and ultimately discharged from the bottom of the bubble tower, and hydrogen sulfide-depleted gas is discharged from the top.
