After gas-liquid separation, the produced liquid of the oil well adopts a dry method or a wet method to desulfurize associated gas, the desulfurized gas is independently and externally conveyed to a joint station, and the separated liquid is conveyed to the joint station in a pipe conveying or tank truck mode. In the oil well production process, the safety risk of hydrogen sulfide leakage exists along the well mouth-gas-liquid separator-desulfurizing device before associated gas is desulfurized. The emergency treatment method adopted for the hydrogen sulfide leakage accident at present mainly comprises physical dilution methods such as fire water spraying, forced ventilation and the like. The fire-fighting water mist method adopts tap water or surface water, and mainly eliminates hydrogen sulfide in gas phase based on the principle that hydrogen sulfide has certain solubility in water. However, the method has two problems, namely, the method generates sulfuric acid after dissolution and has certain corrosiveness; secondly, the dissolution is a physical process, and absorbed hydrogen sulfide can be continuously released, so that secondary damage exists. The current hydrogen sulfide capturing and eliminating patent is mainly focused on a dry powder method.
The patent with the bulletin number of CN103949140A, named hydrogen sulfide leakage emergency trapping and eliminating powder and the production method thereof, relates to hydrogen sulfide leakage emergency trapping and eliminating powder and the production method thereof, and mainly solves the problems of environmental pollution and lower cleaning efficiency in the prior art. The invention adopts the technical scheme that the dry powder mainly comprises 65-99% of the arresting agent, 0.5-15% of the moisture-proof agent and 0.5-20% of the additive by mass percent, wherein the additive is at least one of polyethylene glycol dimethyl ether, N-methyl pyrrolidone, propylene carbonate, tributyl phosphate, N-methyl-epsilon-caprolactam, methanol, alkanolamine, sulfolane, bentonite, carboxymethyl cellulose and sodium carboxymethyl cellulose, and the production method thereof, thereby better solving the problems and being applicable to the emergency arresting of the hydrogen sulfide leakage.

The publication number CN109663473A, named as "high-efficiency hydrogen sulfide gas eliminating dry powder and its preparation process", discloses one kind of high-efficiency hydrogen sulfide gas eliminating dry powder and its preparation process. The invention adopts a trapping and eliminating dry powder for efficiently eliminating hydrogen sulfide gas, which consists of granular active carbon, a modifier, an accelerator and a regulator, wherein the modifier consists of soluble ferric salt, soluble copper salt and soluble zinc salt according to the mass ratio of 1-10: 1 to 10:1 to 10; the promoter is at least one of tetrabutylammonium bromide, tetrabutylammonium chloride and tetrabutylammonium bisulfate; the regulator is at least one of K 2CO3、Na2CO3、KHCO3、NaHCO3; the addition amount of the modifier is 1% -5%, the addition amount of the accelerator is 0.01% -0.1% and the addition amount of the regulator is 0.01% -0.05% relative to the amount of the dried granular active carbon. The principle of desulfurization by the dry powder method is that the desulfurization is mainly carried out by utilizing the oxidation or precipitation reaction of the modifier and hydrogen sulfide, such as the oxidation and precipitation reaction of soluble ferric salt FeCl 3 and hydrogen sulfide, such as Fe 3++H2 S- & gt FeS+S, and the precipitation reaction of soluble copper salt and hydrogen sulfide, such as Cu 2++H2 S- & gt CuS. The main problems in dealing with leaked hydrogen sulfide are: (1) The dry powder for trapping and eliminating is usually composed of 3-4 substances, and usually requires the steps of dissolving, mixing, drying, granulating and the like, and has the advantages of complex preparation process, complex operation and high cost; (2) The desulfurization medium in the dry powder for capturing and eliminating is solid phase, the load and the surface of the porous active carbon, the hydrogen sulfide is gas phase, and the gas-solid phase reaction is carried out, so that the steps of external diffusion, internal diffusion, reaction and the like are needed, the desulfurization reaction is slow, and the treatment efficiency is low; (3) The absorbed solid powder is easy to cause secondary pollution and is not suitable for large-scale open space treatment.
