Title:
段式膜酸化反応装置システム
Document Type and Number:
Japanese Patent JP5525026
Kind Code:
B2
Abstract:
Ion transport membrane oxidation system comprising (a) two or more membrane oxidation stages (1, 3, 5, 7), each stage comprising a reactant zone (1c, 3c, 5c, 7c), an oxidant zone (1a, 3a, 5a, 7a), one or more ion transport membranes (1b, 3b, 5b, 7b) separating the reactant zone from the oxidant zone, a reactant gas inlet region, a reactant gas outlet region, an oxidant gas inlet region, and an oxidant gas outlet region; (b) an interstage reactant gas flow path (1e, 3e, 5e, 7e) disposed between each pair of membrane oxidation stages and adapted to place the reactant gas outlet region of a first stage of the pair in flow communication with the reactant gas inlet region of a second stage of the pair; and (c) one or more reactant interstage feed gas lines (35, 37, 39), each line being in flow communication with any interstage reactant gas flow path or with the reactant zone of any membrane oxidation stage receiving interstage reactant gas. The carbon dioxide partial pressure is maintained at a value that is less than the critical threshold above which the membrane reacts with carbon dioxide and decomposes.
