| Abstract: | Based on introduction of the process of hydrogen production unit by steam reforming of hydrocarbons. The causes of process condensate water, the necessity of recovery and utilization, the composition and causes of impurities in process condensate, reuse of process condensate and reuse conditions are analyzed. Several methods of recovery and utilization of condensate water in different processes, including double steam system, steam stripping, purification treatment and water network integration are emphatically analyzed. Both advantages and disadvantages of various methods and their application conditions are compared. It provides a certain basis for the selection of condensate recovery and utilization methods in hydrogen unit process. Finally, economic analysis of scheme of reusing condensate water by double steam system is given. |
