Abstract: The methods and embodiments described herein involve installation of a gas sparging manifold into crude oil storage tanks, which facilitates removal of hydrogen sulfide (H2S) from bulk crude oil. Hydrogen sulfide stripped from the crude oil is scavenged via a forced-draft scavenging gas into a scavenging duct, and passes through an in-line filter. An alternative embodiment can be adapted for mobile use in a tank trailer/tank car capable of being towed by a tractor truck or locomotive.
