Description

Technical Field

[0001] The utility model relates to the technical field of natural gas deacidification treatment, in particular to an energy-saving amine liquid regeneration tower. Background Art

[0002] The amine liquid regeneration tower is one of the essential key equipment in the natural gas deacidification treatment device. Its purpose is to separate the acidic gas (carbon dioxide, hydrogen sulfide, etc.) in the rich amine liquid and reduce the acidic gas content in the amine liquid to the required range, so as to achieve the purpose of repeated recycling of the amine liquid. The acidic gas evaporated from the top of the regeneration tower is cooled from 97°C to 50°C by the seawater condenser. A large amount of heat is taken away by seawater. On the one hand, there is a large amount of latent heat that cannot be effectively utilized, and on the other hand, it is not conducive to the environmental protection of seawater. Therefore, it is necessary to utilize this part of the heat.

[0003] For example, the publication number CN201910544563.X discloses "An Amine Liquid Regeneration System", which collects excess heat from the amine liquid flash tower through a heat exchange sleeve to heat the water in the insulation pool, thereby saving resources and reducing costs.

[0004] However, since the desalted water preheater is not used effectively, the heat is transferred to the coke oven gas cooler, causing the circulating water return temperature to rise and the evaporation of the circulating water to increase significantly, which will increase the load on the transport pipe and thus affect the life of the transport pipe.
