Abstract
A reduction device, an acid gas recovery device, a recovery device collector, and a first removed substance returning line are provided. The reduction device is configured to perform a reduction process to turn iron oxide to reduced iron by adding a reducing agent. The acid gas recovery device is configured to recover CObeing acid gas with COabsorbing liquid being acid gas absorbing liquid from exhaust gas containing at least powder-shaped iron-based solid substances and the acid gas, which are discharged from the reduction device. The recovery device collector is configured to collect the iron-based solid substance contained in the absorbing liquid with a filter. The iron-based solid substances collected by the recovery device collector are removed, and removed substances containing the removed iron-based solid substances are returned to the reduction device side through the first removed substance returning line.
