Fluctuations in demineralized water during cooling cycles during hydrogen production shutdowns
Thread Content
During the cooling cycle for shutdown in hydrogen production, there are fluctuations in the demineralized water, as well as significant variations in feed volume and temperature. What should be done to address this?
Since production has been halted, it means that hydrogen is no longer required in the subsequent stages. The PSA unit can be shut down, the conversion section can be isolated and sent to the flare, and then the flow rate and temperature can be reduced gradually. That’s all that’s needed
