摘要： A feed gas reforming system is provided. The system includes a reformer configured to receive feed gas and supply water and to produce and discharge mixed gas including hydrogen, a pressure swing absorber (PSA) configured to receive the mixed gas and to refine and discharge hydrogen gas, a feed gas supply unit configured to control the supply amount of feed gas, a supply water supply unit configured to control the supply amount of supply water, a hydrogen gas supply unit configured to control the amount of hydrogen gas, and a control unit configured to control the flow rate of hydrogen gas, to control the feed gas supply unit based on the pressure of the discharged hydrogen gas, and to control the supply water supply unit based on the flow rate of feed gas.

摘要： LNG reformer system may include a reformer configured for reforming raw material gas including LNG gas and water vapor into hydrogen through a catalytic reaction thereof; a hydrogen PSA extracting the hydrogen in reformed gas produced in the reformer; a CO2 PSA fluidically connected to the hydrogen PSA and configured for extracting carbon dioxide in off-gas discharged from the hydrogen PSA; a first heat exchanger fluidically connected to the CO2 PSA and configured for cooling a fluid including carbon dioxide extracted in the CO2 PSA by LNG supplied from an LNG tank toward the reformer; a CO2 separator fluidically connected to the first heat exchanger and configured for separating the carbon dioxide from a fluid that passed through the first heat exchanger, the fluid including carbon dioxide; and a CO2 tank fluidically connected to the CO2 separator and storing the carbon dioxide separated in the CO2 separator.
