A recently granted patent (Publication Number: US11850551B2) discloses a method for removing hydrogen sulfide using a methylmorpholine-N-oxide solution in a vessel containing water and gas layers. The process involves introducing the solution, allowing it to react with hydrogen sulfide in the water layer, and treating the gas layer by enabling the reaction between hydrogen sulfide and the solution. Steam is introduced to remove hydrogen sulfide from the water layer, and adjustments in temperature are made to control the rate of evaporation and condensation of hydrogen sulfide.
Another method outlined in the patent involves similar steps of introducing the solution, allowing it to react with hydrogen sulfide in the water layer, and treating the gas layer. Additionally, recirculation of the water layer within the vessel, along with heating, is employed. The process also includes the introduction of steam to remove hydrogen sulfide and adjustments in temperature to control the rate of condensation.
Furthermore, the patent describes a method that includes introducing the solution, allowing it to react with hydrogen sulfide in the water layer, and treating the gas layer. Increasing the temperature of the water layer is emphasized in this method, along with adjustments in temperature to control the rate of condensation. The patent also mentions adjusting the rate of condensation by increasing the pressure in the vessel and increasing the surface area of the interface between the water and gas layers as additional steps in the process.
