Title:
AMMONIA AND HYDROGEN PRODUCTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/255028
Kind Code:
A1
Abstract:
An ammonia and hydrogen production system (1) comprises: a boiler (20) that generates steam by the heat of a combustion furnace (11); an exhaust gas treatment device (13) that treats exhaust gas from the combustion furnace (11) and discharges exhaust gas treatment wastewater (F1); a separation device (10) that separates boiler blow water (F2) of the boiler (20) into ammonia-containing water (F5) and treated water (F6); a water electrolyzer (32) that electrolyzes the treated water (F6) to produce hydrogen (F7); a hydrogen storage tank (33); an ammonia stripping device (44) for stripping ammonia from the exhaust gas treatment wastewater (F1); and an ammonia water storage tank (51) that stores ammonia water (F8) including stripped ammonia. In the ammonia stripping device (44), the ammonia-containing water (F5) is injected at a first location (P1) and the exhaust gas treatment wastewater (F1) is injected at a second location (P2) different from the first location (P1).
