Abstract

The invention relates to a treatment system and a treatment method for removing hydrogen sulfide from acid gas. The treatment system comprises an absorption reaction unit, a sulphur filtering unit, a solution regeneration unit, a temperature control unit and a medicament deliver unit, wherein the absorption reaction unit has a ferrum-catalyst desulfuration solution, is used for absorbing hydrogen sulfide contained in the acid gas introduced in the ferrum-catalyst desulfuration solution, and oxidizing the hydrogen sulfide into sulphur; the sulphur filtering unit is used for filtering the sulphur; and the solution regeneration unit is used for oxidizing and regenerating the filtered ferrum-catalyst desulfuration solution. The sulphur filtering unit is positioned between the absorption reaction unit and the solution regeneration unit. According to the system and the method, the sulphur is filtered from the solution before the step of oxidation and regeneration, so that the sulphur can not be deposited at the bottom end of an oxidization regenerator, the concentration of the sulphur in the system is low, so that the system can operate stably for a long time, and has good operational flexibility under various work conditions; the structure of equipment can be simplified; the investment is saved; and the construction period is also saved.

Description

technical field

[0001] The invention relates to a gas treatment system and treatment method, in particular to an acid gas removal hydrogen sulfide treatment system and treatment method. Background technique

[0002] Hydrogen sulfide is a very harmful impurity in industrial gases such as petrochemical, natural gas, oilfield development, coke oven gas and semi-water gas. Its existence will not only cause corrosion of equipment and pipelines, but also cause serious harm to the environment, and it is a pollutant that must be eliminated or controlled.

[0003] In the hydrogen sulfide removal process, the large-scale desulfurization system, such as the system with an elemental sulfur output of more than 5,000 tons per year, generally adopts the CLAUS process; for small-scale desulfurization systems, the following two wet catalytic oxidation processes are most widely used. 1) Complex iron catalyst absorption solution; 2) Metal vanadium catalyst absorption solution. In addition, t...
