- the concentration of the target component in the processed gas is substantially zero until a certain time from the start of the gas absorption processing. That is, until this time, the concentration of the target component in the absorbent is not so high, and the absorbent retains a high absorbency. For this reason, until this time, the target component in the gas to be absorbed supplied to the processing unit is almost completely absorbed by the absorption liquid by the absorption process.

- the two-phase flow is, for example, a slag flow or an annular flow.
- the absorption liquid and the discharge gas released from the absorption liquid are in the fine flow path. It is necessary to be able to coexist at a very large gas-liquid ratio. However, since the inside of the fine channel is extremely limited, such coexistence is actually difficult. As a result, the gas-liquid ratio is not sufficient, and the pressure of the gas released in the fine channel cannot be lowered sufficiently. For this reason, the gas of the target component absorbed in the absorption liquid cannot be sufficiently released in the fine channel.

- the absorption liquid whose concentration of gas absorbed by the gas absorption process is increased and the absorption capacity is reduced is reduced by reducing the concentration by the gas release process. It can be recovered and again subjected to gas absorption treatment. For this reason, the efficiency of the gas absorption process can be improved as compared with the case where the absorption liquid having a reduced absorption capacity is continuously used for the gas absorption process.
