Abstract

The invention relates to the technical field of crude oil gas treatment, in particular to a preparation method of a sulfur-containing crude oil gas treating adsorbent. The sulfur-containing crude oilgas treating adsorbent comprises a gemini surfactant, a hydrophilic emulsifier, a sodium hydroxide, water and the balance of dimethicone, wherein the gemini surfactant is one of p-phenyldimethyl dialkyl phosphate, 2,2-bis(sodium 4-hexadecyloxy-3-benzenesulfonate) propane and dimethylene 1,2-bis(dodecyl dimethyl ammonium bromide); the hydrophilic emulsifier is one of sorbitan monooleate, polyglyceryl stearate and polyoxyethylene fatty acid ester. The components are compounded to form a stable water-in-oil emulsion, alkali dispersed-phase water in the emulsion can absorb hydrogen sulfide gas, and the continuous-phase dimethicone outside the emulsion can absorb hydrocarbon molecules to treat the hydrocarbon molecules and the hydrogen sulfide at the same time, so that the oil gas treatment efficiency is high; in addition, the preparation process is simple.

Description

technical field [0001] The invention relates to the technical field of crude oil gas treatment, in particular to an adsorbent for treating sulfur-containing crude oil gas and a preparation method. Background technique [0002] Oil and gas recovery refers to the collection of volatilized gasoline and oil vapor during the process of loading and unloading gasoline and refueling vehicles, so as to prevent air pollution caused by volatilization of oil and gas, eliminate potential safety hazards, reduce economic losses, and obtain considerable returns. At present, common methods include absorption method, condensation method, membrane separation method and adsorption method. The existing absorption method generally uses lean oil such as diesel oil as absorbent, and the recovery efficiency is low; the condensation method uses refrigeration technology to directly convert the oil and gas components from the gas phase to the liquid phase, but the investment is high and the short-term ...
