Abstract: In one embodiment, an acid gas removing apparatus includes an absorber configured to bring a first gas including an acid gas and a lean solution into contact to discharge a rich solution that is the lean solution having absorbed the acid gas, a regenerator configured to separate the acid gas from the rich solution discharged by the absorber to discharge the lean solution that is the rich solution separated from the acid gas, and a measuring instrument configured to measure a temperature of the rich or lean solution in the regenerator. Furthermore, an acid gas removal control apparatus that controls the acid gas removing apparatus includes a receiver configured to receive the measured temperature, and a controller configured to control resupply of a resupplied solution to the rich or lean solution or removal of an acid component from the rich or lean solution, based on the received temperature.

Abstract: A porous metal organic framework having gas adsorption selectivity and excellent water resistance, an adsorbent consisting of the porous metal organic framework, and a method for separating carbon dioxide using the same are provided, which are: a porous metal organic framework, which is characterized by comprising a metal oxalate, a cycloazocarbyl compound, and a bidentate organic ligand; an adsorbent consisting of the porous metal organic framework; and a method for separating carbon dioxide using the same.

Abstract: According to one embodiment, a gas processing equipment includes an oxygen remover 2 that removes oxygen contained in exhaust gas G, and a gas processing device 3 that processes pretreated exhaust gas G (P), from which the oxygen has been removed by the oxygen remover 2, with a carbon dioxide absorbent solvent S as a treatment agent.
