Abstract

A method for dynamically evaluating the sulfur removal efficiency of a triazine sulfur removal agent is characterized in that hydrogen sulfide continuously goes through the sulfur removal agent at a certain concentration at a certain speed under simulated onsite dynamic conditions, and is absorbed in the hydrogen sulfide and sulfur removal agent contact process in order to reflect the practical onsite application effect. The method has the advantages of simplicity in flow and operation, accurate control of the concentration and the flow speed of hydrogen sulfide, and realization of accurate determination of the sulfur removal efficiency, the sulfur removal capacity and the optimum addition of the sulfur removal agent.

Description

technical field [0001] The invention relates to the technical field of sulfur removal in oil and gas fields, in particular to a dynamic evaluation method for sulfur removal efficiency of a triazine sulfur removal agent. Background technique [0002] Hydrogen sulfide widely exists in associated gas and natural gas in oil and gas fields, and the existence of hydrogen sulfide is a major hazard to the health of oil and gas production and operators. In order to eliminate the hazards of hydrogen sulfide gas, it is often necessary to add sulfur removal agents to remove hydrogen sulfide gas before oil and gas production. However, there is still a lack of effective means for the evaluation of sulfur removal agents. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of prior art, the object of the present invention is to provide a kind of dynamic evaluation method of desulfurization efficiency of triazine desulfurizer, can simulate on-site hydro...
