Abstract: A two-stage electrodialysis system and a method for recovering waste CO2-lean amine solvent are provided. The system includes an amine solution pretreatment filtering system, a C-A homogeneous membrane electrodialysis device, a BP-A bipolar membrane electrodialysis system, and a CO2 recovery and capture system. The C-A homogeneous membrane electrodialysis system includes a material chamber, a C-A homogeneous membrane electrodialysis device, a concentrated HSSs waste solution chamber, an electrode solution chamber, and corresponding pipelines and peristaltic pumps. The BP-A bipolar membrane electrodialysis system includes a secondary feed chamber, a BP-A bipolar membrane electrodialysis device, an acid liquor chamber, an electrode solution chamber, and corresponding pipelines and peristaltic pumps. The waste CO2-lean amine solvent enters the material chamber after passing through the amine solution pretreatment filtering system. The concentrated HSSs waste solution chamber is connected to the secondary feed chamber by a buffer tank.

Abstract: A dual-cavity method and device for collecting and storing solar energy with metal oxide particles. Solar radiation irradiates into a light receiving cavity of a dual-cavity, heat-collecting reactor to heat a separating plate and preheat metal oxide particles. The preheated metal oxide particles then enter a reacting cavity. As temperature increases, the metal oxide particles reduce to release oxygen, which discharges through a gas outlet. Reduced metal oxide particles discharge through a particle outlet into a particle storage tank, and then into an oxidation heat exchanger to react with the discharged oxygen discharged to release and transfer stored chemical energy to a medium to be heated. The oxidized metal oxide particles are conveyed into a storage tank, and again enter into a particle inlet of the light receiving cavity. Ambient air controls the gas flow rate in the reactor and the reacting rate in exchanger.
