888 methods have much representativeness.And the design of these techniques is to be applied to removing H2S, though for the SO in gas2Have with organic sulfur
Certain removal effect, but can cause the side reaction to increase, the drawbacks of operating cost is high.
For SO2Removing it is domestic at present mainly in flue gas desulfurization field, flue gas removing SO2It is generally divided into dry method, wet
Method, semidry method, the desulfurization of wherein lime stone-gypsum wet are most widely used.But the design of these techniques is also de- with flue gas
Except SO2Based on, for removing SO in unstripped gas2And H2S is not applied to simultaneously.
Organosulfur compound is main with sulphur carbonoxide（COS）Based on, a small amount of carbon disulfide, mercaptan, thiophene are also contained in addition
Fen etc..Removing organic sulfur uses most technique or hydrolyzation catalysis Dry Adsorption method at present, and the technique desulfurization has purification
Degree is high, the characteristics of various organic sulfur compounds can be removed, though for SO2And H2S has a desulfurization precision very high, but be simply applied into
Mouth sulfur content gas less high.
In sum, several sulfur removal technologies are still relatively more significant in the effect of a certain sulphur of simple removing, but if gas
There is diversified forms sulphur simultaneously in body, this several technique just seems awkward, if hardness superposition will result in desulfurization pair
Reaction increases, and causes the waste of fund and equipment, and do not reach expected desulfurized effect.
