The control means (10) calculates the combustion rate coefficient C of mixed gas with respect to a reference fuel on the basis of equation (1). Equation (1): S0=SH×C+SA×(1−C). In equation (1), S0 is the combustion rate of the reference fuel, SH is the combustion rate of hydrogen, SA is the combustion rate of ammonia, and C is the combustion rate coefficient of mixed gas. In addition, on the basis of equation (2), the control means (10) determines the volume fractions of ammonia and hydrogen that are supplied to the mixing tank. Equation (2): C=1−exp(−A×MB). In equation (2), M is the volume fraction of hydrogen in mixed gas, and A and B are constants.

摘要： A process for producing methanol from an adjusted make-up gas comprising the steps of adjusting the stoichiometric number of the make-up gas fed to the methanol loop with a first stream of hydrogen recovered from a minor portion of makeup gas separated from the main stream, and a second stream of hydrogen recovered from the loop purge; the process further comprises the step of feeding at least a portion of a tail gas rich in methane to a reforming stage for use as a feedstock to produce the make-up gas.

摘要： Processes for producing a hydrogen-enriched gas stream are described. A hydrocarbon containing feed is processed in a hydrogen production process unit, and the synthesis gas formed is subjected to a water gas shift reaction. The shifted synthesis gas is sent for processing to recover hydrogen and carbon dioxide. The hydrogen and carbon dioxide recovery processes involve separating a purified hydrogen product stream and a purified carbon dioxide stream from the shifted synthesis stream and recycling synthesis gas to the reforming feed after recovery of CO2 and H2, thereby avoiding carbon slip from the process and lowering the overall carbon intensity.

摘要： A hydrogen-producing device is provided which can start up without receiving an energy supply from the outside. This hydrogen-producing device 1 is provided with an input unit 11 which is connected to a hydrogen source 41, a reformer 12 which produces a hydrogen-containing gas, a hydrogen storage container 13, a fuel battery 15 which generates power using the hydrogen-containing gas, and a control unit 18. The hydrogen storage container 13 is connected to a fuel hydrogen supply path 16 for supplying hydrogen to the fuel battery 15, and to an external supply path 17 which supplies hydrogen to an external load 42. The control unit 18 stores a threshold value of the hydrogen-containing gas necessary for start-up of the fuel battery 15, and controls the amount stored in the hydrogen storage container 13 to be greater than or equal to the amount necessary for start-up of the fuel battery 15. Further, when starting up the hydrogen-producing device, the fuel battery 15 generates power by receiving a supply of the hydrogen-containing gas stored in the hydrogen storage container 13 and supplies power to the reformer 12 from a power supply path 30. The reformer 12 starts up and hydrogen is produced.

摘要： A sweep membrane separator includes a membrane that is selectively permeable to a selected gas, the membrane including a retentate side and a permeate side. A mixed gas stream including the selected gas enters the sweep membrane separator and contacts the retentate side of the membrane. At least part of the selected gas separates from the mixed gas stream and passes through the membrane to the permeate side of the membrane. The mixed gas stream, minus the separated gas, exits the sweep membrane separator. A sweep gas at high pressure enters the sweep membrane separator and sweeps the selected gas from the permeate side of the membrane. A mixture of the sweep gas and the selected gas exits the sweep membrane separator at high pressure. The sweep membrane separator thereby separates the selected gas from the gas mixture and pressurizes the selected gas.
