Control of production amount of hydrogen in hydrogen production device
专利汇可以提供Control of production amount of hydrogen in hydrogen production device专利检索，专利查询，专利分析的服务。并且PURPOSE: To produce hydrogen in an amount corresponding to load while minimizing waste consumption, by adding time lag element to a pressure regulator depending upon pressure variability at the outlet of a hydrogen production device, controlling a flow rate of raw material and regulating the amount of hydrogen discharged out of the system.
CONSTITUTION: A raw material consisting of off-gases 1 and 2 and hydrocarbons such as naphtha, etc., is heated by a furnace 1 and desulfurized by a desulfurizing column 2. Then the raw material is reformed with steam by a reforming furnace 3 and further formed CO
2 is removed by a decarboxylation device 4 to give hydrogen. In the hydrogen production device having the constitution, load variability is detected by a pressure detector P
3 set at the outlet side of the device. The detected output is inputted in parallel to pressure regulators C
4 and C
5 having different et values. Time lag element X is added to one pressure regulator C
5 having a lower pressure set value and a flow rate of the raw material at the inlet side of the desulfurizing device is controlled by regulators C
1 and C
2 . And simultaneously the amount of hydrogen discharged out of the system, such as flare, etc., is controlled by the other pressure regulator C
4 having a higher pressure set value.
