Hydrogen sulfide (H2S) occurs naturally in petroleum reservoirs, but must be removed from crude oil prior to transportation from drilling sites to storage tanks at petroleum refineries. H2S is corrosive to storage tanks, pipelines and railcars, and without proper treatment, can generate flammable and dangerous vapors.

RevH2S, is a patented pending, closed-loop unit that strips H2S from crude oil using an inert gas. It does not react with any components of the crude oil or change any properties of the oil, beyond removing H2S.

A single RevH2STM unit can treat 3,000 to 9,000 bpd of sour crude with H2S concentrations levels up to 300 ppmw. Greater capacity can be achieved by the use of multiple RevH2S units.

Yes. For higher H2S concentrations, the crude can be cycled through the RevH2S unit multiple times for further treatment, so there is no limit to the H2S levels that RevH2S can treat.

RevEnergy owns and operates RevH2S for customers through a service lease agreement. A RevEnergy team member will be stationed onsite to operate the RevH2S and continuously monitor the process to ensure the target H2S concentration is achieved.

The cost of the RevH2S is competitive with other commercial H2S treatment methods. Unlike other methods however, the RevH2S has the advantage of a closed-loop system that doesn’t release H2S into the atmosphere.

This saves users significant time and money and there is never any volume loss.

Other operational expenses for the RevH2S include the supply of the gas feedstock, electricity, and waste disposal.


A single RevH2S unit is roughly the size of a cargo container – 40 feet by 8 feet.

RevH2S uses a proprietary method to strip hydrogen sulfide with an inert gas. The identity of the gas is proprietary, however, it’s use is extremely safe. It does not cause a chemical reaction when introduced to crude oil or change the properties of the crude – it only removes the H2S.

A 3,000 bpd RevH2S unit requires less than 600 horsepower or 450 kilowatts of electricity, so the unit can be run from a generator or directly from the grid.

Yes. A harmless waste product is created through the process. The quantity of waste depends on the volume of raw crude being treated and the concentration of H2S within the crude. The non-hazardous waste can be disposed of easily with facility-produced water, such as in production disposal wells or safely trucked offsite by a third-party disposal company.
