Study on CO_2 Recovery Systems by Pressure Swing Adsorption under High Pressure Condition
The numerical simulations for adsorption and desorption of CO_2 under high pressure conditions are conducted to predict distributions of CO_2 concentration, gas temperature, adsorbed amount of CO_2, etc. in the adsorption tower as a function of decompression time. The decompression time, which is the period to decrease pressure in desorption process, changes the performance of the system. We seek the optimum decompression time to minimize the thermal energy loss in the range for 10 to 150s. As a result, it is revealed that the optimum decompression time is about 40s and the thermal energy loss is about 250[kJ/kg-CO_2].
