Objective To solve the key problems of power matching between process of CO 2 steam desorption and process of steam generation, as well as water/vapor separation. Method Solid amine desorption process was studied by thermodynamic analysis and experiments.The distribution rule of desorption energy was found out and then the power consumption of steam generator was decided. Ceramic insert was designed to separate water and vapor making use of surface tension. Finally,the steam generator was designed on system requirements. Result Experiments proved that the steam generator can satisfy the demand of the system as well as successfully separate water and vapor, in addition, the selected power is suitable. Conclusion The design on steam generator was right and practicable.
