It corresponds to a reforming unit with an average reaction pressure of 1.47–1.67 MPa, and the water content in the recycle gas is 20–35 uL/L. However, the average reaction pressure in current continuous reforming is 0.3 MPa; is it still applicable to the condition where the water vapor pressure should be maintained at 40–60 Pa?
It is sufficient to mainly analyze the water content in the hydrogen used in the reforming process; 20–30 ppm is adequate. Currently, in continuous reforming, water injection is basically not used; it is sufficient to control the chlorine content on the catalyst.
With different reaction pressures, the water content at the same partial pressure varies! It is sufficient to keep the water content in the recycle gas at 20–30 ppm
