The triethylene glycol dehydration and regeneration simulating experiment system includes a medium source, a triethylene glycol dehydration device and a triethylene glycol regeneration device. The medium source includes a simulation air source and a triethylene glycolliquid source, wherein the simulation air source is successively connected with an impure air source, a pure water source and an air inlet of the triethylene glycol dehydration device. An inlet of atriethylene glycol barren solution in the triethylene glycol dehydration device is connected with the triethylene glycol liquid source, an outlet of a triethylene glycol rich solution in the triethylene glycol dehydration device is connected with an inlet of the triethylene glycol regeneration device, and an outlet of the triethylene glycol barren solution of the triethylene glycol regeneration device is connected with the triethylene glycol liquid source through a refluxing pipe. The triethylene glycol dehydration device and the triethylene glycol regeneration device further form a medium refluxing closed loop with the simulation air source, the impure air source and the pure water source. The triethylene glycol dehydration and regeneration simulating experiment system has the beneficialeffects that the technique of dehydrating natural gas and the situation of regenerating dehydrating agent triethylene glycol are simulated, situations of dehydrating the triethylene glycol rich solution under different conditions are simulated by the triethylene glycol regeneration device, and full-closed-loop recycling utilization formed by various media in experiments is participated. Therefore,the cost of the experiments and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of triethylene glycol regeneration experiments, in particular to a triethylene glycol dehydration and regeneration simulation experiment system based on medium circulation. Background technique [0002] At present, with the development of technology and the requirements of energy saving and emission reduction, the traditional triethylene glycol dehydration method has been widely used in the natural gas dehydration process. Due to the influence of various factors, the loss of triethylene glycol consumption is huge. The laboratory often discards the triethylene glycol after being used once, and will not use it again, which greatly increases the cost of production or experiment. However, as a water-absorbing agent, triethylene glycol does not achieve its water-absorbing capacity through an irreversible chemical reaction, so it only needs to strip off the absorbed water again, then triethylene glycol can be used...

Problems solved by technology

[0003] In the actual process of TEG regeneration, due to the lack of theoretical guidance, most of them rely on past experience to formulate measures, so that the service life of TEG cannot achieve the desired effect, and it is even impossible to know the factors that lead to the shortened life of TEG. Which, unable to overcome the problem in a targeted manner, makes the regeneration effect of triethylene glycol poor
