We propose a modular retrofit that transforms this liability into three profit centers: hydrogen, captured CO\u2082, and electricity. Aspen Plus simulations size two staged water-gas-shift reactors achieving \u226597 % CO conversion, followed by amine absorption to capture \u226595 % of the CO\u2082 and PSA units delivering \u226595 %-pure H\u2082 at \u226590 % recovery. Heat released in the exothermic shift drives a steam turbine, offsetting utility costs. Economic modeling with CAPCOST and Monte-Carlo analysis projects an expected 14 % internal rate of return and a discounted payback of 9.6 years.\u00a0\u00a0<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Turning steelmaking\u2019s carbon-rich off-gas into blue hydrogen, our team\u2019s integrated process converts \u226597 % of CO to H\u2082, captures \u226595 % of the CO\u2082, and recovers heat to generate on-site power\u2014delivering clean fuel and revenue from a single waste stream.\u00a0<\/p>\n","protected":false},"author":47,"featured_media":13006,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_eb_attr":"","footnotes":""},"categories":[11,14,20],"tags":[],"class_list":["post-13000","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-design-day-news","category-news","category-project-spotlight"],"acf":[],"yoast_head":"\n
