| titleOfInvention | Hydrogen sulfide absorption method and equipment |
| abstract | (57) Summary Disclosed is a method and apparatus for selectively removing hydrogen sulfide from a gas containing hydrogen sulfide and carbon dioxide by liquid absorption. In the first step of the process, the gas (3) is a carbonate-containing alkaline solution whose pH is adjusted during absorption in at least one step by the addition of a hydroxide such as sodium hydroxide in the vessel (1). Contact with. In the second step of the process, the gas is combusted in a combustor (32) to convert the hydrogen sulfide remaining in the gas to sulfur dioxide, which is then in a wet cleaner (36). Absorb in an alkali-containing solution such as a solution. By combining the step of absorbing hydrogen sulfide with a carbonate-containing solution in the first step and the step of burning residual hydrogen sulfide into sulfur dioxide to absorb the generated sulfur dioxide in an alkaline solution in the second step, high selection can be achieved. It is possible to achieve total hydrogen sulfide separation with good performance, high resolution and good process economy. |
