Medium-pressure steam for methanol-to-hydrogen production
Thread Content
Our methanol-to-hydrogen plant uses medium-pressure steam and a vaporization tower process, with two identical systems in total. At present, the feed volume to each system is roughly the same, but one system consumes three tons more medium-pressure steam than the other Could that expert help analyze it?
Check the insulation condition along the system, especially in the underground section. A leakage rate of 3 tons per hour is quite high.
All the valves also need to be checked.
Take a look at what the conversion rates are for your two sets of catalysts Was the catalyst used for the same amount of time? If the lifetime of one of the catalyst sets reaches its end, the heat absorption will increase, which in turn leads to higher steam consumption!
How is the conversion rate calculated? The catalysts on both sides were used for the same duration, and the reaction temperatures were also similar
It’s more or less the difference; heat absorption varies depending on the temperature difference! As for the conversion rate, indicators such as the amount of accumulated liquid after the reaction can be used to assess it. It would be best to have your catalyst manufacturers make a judgment or conduct a material balance!
By checking the methanol content in the wash tower and the temperature, it is possible to roughly determine which stage the catalyst is in
