H2S Bubble Stripping w/ Gas Sparging

H2S Bubble Stripping w/ Gas Sparging

Just putting this out there, but I am wondering if it is possible to strip H2S out of crude by sparging a small amount of sweet gas through a vessel. The vessel is about 40 ft long, so sparging lances could be put every 5 ft or so to achieve good contacting. The H2S PPM needs to be reduced from about 70 to 10, and a reasonable amount of gas will do the trick.

Has anyone every seen this done? Is there a better way to go about doing this? Will foaming be an issue? The problem with using an H2S stripping column for the final stage is the very low gas rate.
