  • Acid gas absorption process
    Patent number: 5340382
    Abstract: Acid gas (a mixture of carbon dioxide and hydrogen sulfide) is absorbed by produced water from hydrocarbon wells. The acid gas is absorbed in the produced water in a static mixer. The time from the entry of the produced water into the static mixer to its exit is less than ten seconds. The produced water with the absorbed acid gas is pressurized to flow through a pipeline to an injection pump. The injection pump injects the produced water with the absorbed acid gas into injection wells which return the produced water into disposal strata. The produced water with the acid gas is maintained at a pressure higher than the pressure at the exit of the static mixer.
