(EN) One aspect of the present invention is a gas treatment method, comprising an absorption step of bringing a gas to be treated, which contains carbon dioxide and a sulfur compound, into contact with an absorption solution that performs phase separation by carbon dioxide absorption, thereby causing the carbon dioxide and the sulfur compound to be absorbed by the absorption solution; and a first release step of heating the absorption solution that was brought into contact with the gas to be treated to at least a temperature at which the carbon dioxide absorbed in the absorption solution is released from the absorption solution, but below the temperature at which the sulfur compound absorbed in the absorption solution is released from the absorption solution, thereby releasing the carbon dioxide from the absorption solution.
(ZH) 本发明一个方面涉及气体处理方法，其包括以下步骤：吸收步骤，通过使含有二氧化碳和硫化合物的被处理气体与通过吸收二氧化碳而进行相分离的吸收液接触，从而使所述吸收液吸收所述二氧化碳和所述硫化合物；以及第一释放步骤，通过将与所述被处理气体接触后的吸收液加热至被吸收到所述吸收液中的二氧化碳从所述吸收液释放的温度以上且低于被吸收到所述吸收液中的硫化合物从所述吸收液释放的温度，从而使所述二氧化碳从所述吸收液释放出来。
