A filtering and defoaming combined treatment device for amine liquid comprises a two-section type adsorption filtering device and a defoaming mechanical filtering device. The filtering and defoaming combined treatment device for the amine liquid can purify the amine liquid through the two-section type adsorption filtering device and the defoaming mechanical filtering device, the amount of equipment is reduced, the investment cost is lowered, occupied space is also reduced, and the filtering and defoaming combined treatment device can be implemented on a modularized and prying-installing natural gas purification device. By the adoption of the two-stage filtering process, the same purification effect of an amine liquid system is guaranteed, a three-stage filtering process is simplified, the amount of equipment is smaller, management and maintenance are facilitated, meanwhile, the number of external valves, for connection, between the equipment is reduced, the probability of valve leakage is reduced, and safety is improved. In addition, according to the pollution degree of the amine liquid, the filtering process can be selected and adjusted and is further simplified, the service life of an adsorber is prolonged, the maintenance period of the equipment is prolonged, and the maintenance cost of the equipment is lowered.
Description
technical field [0001] The invention relates to the technical field of purification equipment in the natural gas industry, in particular to an amine liquid filtering and defoaming compound treatment device. Background technique [0002] Activated MDEA mixed amine method is one of the most commonly used methods for natural gas desulfurization and decarbonization. Its advantages are low energy consumption, low degradation rate, low corrosiveness and wide application. In the established natural gas purification projects, the operation of the process unit is generally relatively stable, but due to the fact that the raw gas components contain heavy hydrocarbons, organic acids and other substances, the fine suspended particles generated by the corrosion of the device itself, and the degradation products of amines in the solution are a combination of factors. , it is easy to cause the phenomenon of amine liquid foaming and liquid blocking, which affects the stability of the purific...
