Thermal balance measures for a absorption tower? ?

The main measures for achieving thermal balance in the absorption tower of the aqueous solution process are: 1. The size of the heat exchange area in the steam generation and energy recovery section. If the heat exchange area is made slightly larger, it facilitates the recovery of the heat released during the washing and absorption of dimethyl liquid by ammonia gas, thereby reducing the heat load entering the first absorption tower. Conversely, it increases the heat load entering the absorption tower. 2. The heat exchange area of the external cooler. The reasoning is the same as in 1, so it will not be repeated here. 3. The volume of the vaporization absorption section in one absorption tower. A larger volume facilitates the washing and absorption of oxygen and carbon dioxide, thereby reducing the heat load entering the distillation section of the absorber ； Conversely, it increases the heat load entering the distillation section of a suction tower. 4. The amount of ammonia that returns during suction. The role of the recirculating ammonia is not only to wash and absorb all of the CO2 that enters the refining section of the absorption tower, but it also helps to control the thermal balance. Using a larger amount of recycled ammonia can help reduce the temperature in one of the absorption towers ； Conversely, a suction tower may rise.

The main measures for achieving thermal balance in the absorption tower of the aqueous solution process include: the size of the equipment, such as the heat exchange area of the vaporization heat recovery section； The heat exchange area of the external cooler ； The volume of the vapor absorption section in a suction tower. The magnitude of the process flow rate, such as the amount of ammonia returning in the suction stream ； The amount of absorbent solution in the fine washing stage ； The volume of Solution Type I.
