Abstract
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.
Claims9
A feed gas reforming system comprising:
- a reformer configured to:
- receive feed gas and supply water;
- and
- produce and discharge mixed gas including hydrogen;
- a pressure swing absorber (PSA) configured to:
- receive the mixed gas from the reformer;
- and
- refine and discharge hydrogen gas;
- a feed gas supply unit configured to control a supply amount of the feed gas;
- a supply water supply unit configured to control a supply amount of the supply water;
- a hydrogen gas supply unit configured to control an amount of the hydrogen gas discharged from the PSA;
- and
- a control unit configured to:
- control a flow rate of the hydrogen gas discharged through the hydrogen gas supply unit;
- control the feed gas supply unit based on a pressure of the discharged hydrogen gas;
- and
- control the supply water supply unit based on a flow rate of the feed gas discharged through the feed gas supply unit,
- wherein the control unit further comprises a hydrogen gas controller configured to:
- control the hydrogen gas supply unit based on a flow rate or pressure of the hydrogen gas discharged from the PSA;
- and
- control the hydrogen gas supply unit according to a signal transmitted from outside,
- wherein the hydrogen gas controller further comprises:
- a first pressure sensor configured to measure the pressure of the hydrogen gas discharged from the PSA;
- and
- a first pressure indicator controller configured to control the hydrogen gas supply unit based on the measured pressure,
- wherein when a disturbance occurs in which a composition of the feed gas is changed, the control unit controls the hydrogen gas supply unit to discharge the hydrogen gas at a uniform pressure.
