摘要： In a dehydration equipment, a regenerative gas heater heats a portion of CO2 gas dehydrated in an adsorption tower that is performing an adsorption process and supplies the gas to an adsorption tower that is performing a regeneration process. A regenerative gas preheater performs heat exchange between the CO2 gas that will be supplied to a regenerative gas heater and the CO2 gas sent out from the adsorption tower that is performing the regeneration process. Then, in the dehydration equipment, a regenerative gas cooler cools the CO2 gas that has been sent out from the adsorption tower that is performing the regeneration process and exchanged heat, separates water from the cooled CO2 gas, and returns the resulting gas to the adsorption tower. Thus, the dehydration equipment can prevent an increase in utility consumption due to the regeneration process.
摘要翻译：在脱水设备中，再生气体加热器对正在进行吸附过程的吸附塔中脱水的一部分CO 2气体进行加热，并将气体供给到正在进行再生处理的吸附塔。再生气体预热器在供给再生气体加热器的CO 2气体与从正在进行再生处理的吸附塔排出的CO 2气体之间进行热交换。然后，在脱水装置中，再生气体冷却器冷却从进行再生处理的吸附塔排出的二氧化碳气体并进行热交换，从冷却的CO 2气体中分离出水，并将所得气体返回至吸附塔。因此，脱水设备可以防止由于再生过程而导致的功耗消耗的增加。

摘要： A regeneration tower 7 of a CO2 recovery unit includes an upper regeneration portion 51 that has a tray portion 45, a lower regeneration portion 52 provided below the upper regeneration portion 51 and having a liquid dispersion portion 46, and a supply line L5 that supplies absorbing liquid stored in the tray portion 45 to the liquid dispersion portion 46. The supply line L5 is provided with a heat exchanger 53, and the absorbing liquid is circulated using the density difference between the absorbing liquid flowing before the heat exchanger 53 and the absorbing liquid flowing after the heat exchanger 53 as a driving force. This reduces the cost of equipment while reducing the power in the delivery of the absorbing liquid in the regeneration portion.
