Description
Technical Field
The utility model belongs to the field of desulfurizing agent evaluation, and particularly relates to a desulfurizing agent digital evaluation device.
Background
The liquid desulfurizing agents which have been commercialized at present include: amine desulfurizing agents, triazine desulfurizing agents, hemiacetal desulfurizing agents, oxidation desulfurizing agents and the like, liquid desulfurizing agents with different characteristics are selected according to different hydrogen sulfide concentrations and gas flow rates of source gases, and desulfurization evaluation experiments are often involved in the process of developing new desulfurizing agents and testing and evaluating the existing desulfurizing agents.
Currently, in the process of evaluating the desulfurizing agent, there are two modes:
1. and directly introducing hydrogen sulfide standard gas or sulfur-containing natural gas into a desulfurizing agent absorption bottle through a pressure reducing valve, then introducing into a zinc acetate reaction bottle, and finally introducing into a tail gas absorption bottle. The concentration of hydrogen sulfide absorbed by the desulfurizing agent was calculated by titration of the zinc acetate solution by iodometry. The method is short in time, when the directly-introduced gas flow is large, local hydrogen sulfide concentration is easy to be excessively high, and uneven gas-liquid mixing can cause a large amount of hydrogen sulfide not to fully contact with the desulfurizing agent so as to directly escape into the tail gas of the evaluation device, so that the concentration of the tail gas hydrogen sulfide is abnormally increased, and the actual measured desulfurizing capacity of the desulfurizing agent is lower than an actual value.
2. And (3) utilizing a Kipp generator to react ferrous sulfide with dilute sulfuric acid to prepare hydrogen sulfide gas, introducing the prepared hydrogen sulfide into a desulfurizing agent absorption bottle, then introducing into a zinc acetate reaction bottle, and finally introducing into a tail gas absorption bottle. The concentration of hydrogen sulfide absorbed by the desulfurizing agent was calculated by titration of the zinc acetate solution by iodometry. The method for preparing the hydrogen sulfide has the advantages of slower speed, long test time and poor repeatability, the desulfurizing agent can fully absorb the hydrogen sulfide, dilute sulfuric acid is needed for preparing the hydrogen sulfide, and personnel injury easily occurs due to improper operation.
In addition, the liquid sulfur removal agent evaluation methods all use an iodometric method to measure the concentration of hydrogen sulfide, a large amount of titration reagents such as sodium thiosulfate solution, iodine solution, dilute hydrochloric acid, starch indicator and other chemical reagents are required to be prepared, and personnel injury is easy to occur due to improper operation; the whole titration process needs to remove the reagent for many times, and the accuracy of reagent removal and judgment of the titration end point all have errors to influence the calculation of the desulfurization capacity.
Aiming at various loopholes and defects in the prior liquid desulfurizing agent evaluation device and method, the utility model provides the liquid desulfurizing agent evaluation device which is safe to operate and accurate to evaluate.
