1. Increase system pressure； 2. Improve the purity of recycled hydrogen ； 3. Improve the purity of fresh hydrogen and the amount of fresh hydrogen supplied ； 4. Increase the discharge volume of recycled hydrogen ； 5. Add a circulating hydrogen desulfurization system
Increase the purity of recycled hydrogen, raise the amount of fresh hydrogen added, increase the discharge of waste hydrogen, and raise the system pressure
Increase the amount of hydrogen gas discharged, reduce the temperature of cold high-pressure fractions, improve the purity of fresh hydrogen, and enhance the desulfurization of recycled hydrogen
Increase system pressure, improve the purity of fresh hydrogen, increase the flow rate of recycled hydrogen, and enhance its purity
Increase pressure, hydrogen purity. The hydrogen partial pressure is equal to the system pressure multiplied by the hydrogen purity
Increase system pressure; improve hydrogen purity
1) Increase the pressure of the entire system； 2) Improve the purity of new hydrogen ； 3) Increase the flow rate of recycled hydrogen ； 4) Improve the purity of recycled hydrogen ； 5) Increase waste hydrogen emissions ； 6) Reduce the amount of low-pressure gas flowing to the inlet of the new hydrogen machine.
(1) Increase the pressure of the entire system； (2) Improve the purity of the supplementary hydrogen ； (3) Increase the flow rate of recycled hydrogen ； (4) Improve the purity of recycled hydrogen ； (5) Increase the emission of waste hydrogen ； (6) Reduce the amount of low-pressure gas flowing to the inlet of the new hydrogen machine.
1 Increase the pressure of the entire system. 2 Increase the purity of fresh hydrogen. 3 Increase the flow rate of recycled hydrogen. 4 Improve the purity of recycled hydrogen. 5 Increase the amount of waste hydrogen discharged. 6 Reduce the flow rate of low-pressure gas at the inlet to the fresh hydrogen machine
1) Increase the pressure of the entire system； 2) Improve the purity of new hydrogen ； 3) Increase the flow rate of recycled hydrogen ； 4) Improve the purity of recycled hydrogen ； 5) Increase the emission of waste hydrogen. 6) Reduce the amount of low-pressure gas sent to the inlet of the new hydrogen machine.
