污水汽提与溶剂再生热自循环系统
By using a wastewater stripping and solvent regeneration heat self-circulation system, dual recovery of waste heat from purified water, lean amine solution, and condensate is achieved, forming a closed-loop heat circulation within the system. This solves the problem of high steam consumption in existing processes and achieves significant energy-saving effects.

AI Technical Summary
In existing processes, the energy consumption of wastewater stripping units and solvent regeneration units remains high, mainly because the waste heat of materials in the tower and the waste heat of reboiler condensate are not fully recovered, resulting in excessive steam consumption.
The system employs a wastewater stripping and solvent regeneration heat self-circulation system. Through the combination of a wastewater stripping tower, a wastewater stripping reboiler, a solvent regeneration tower, a solvent reboiler, a steam generator, and a steam compression unit, it achieves dual recovery of waste heat from purified water, lean amine solution, and condensate. The steam compression unit forms a closed-loop circulation, replacing part of the externally supplied high-quality steam.
It achieves deep recovery of waste heat and closed-loop circulation of heat within the system, reducing fresh steam consumption by more than 30%, achieving an overall energy saving rate of 31.7% to 33.8%, and reducing operating costs by 27%.
