The necessity of online analytical instruments in methanol-to-hydrogen plants
Thread Content
Good evening, everyone. Our company has a methanol-to-hydrogen production unit. During the technical discussions, there was no mention of online analysis for gases such as CO, CO2, and O2. When we inspected other companies’ units, we saw that they were equipped with monitoring devices. Is it necessary to use online analysis? What are the reasons for this? Thank you all
Online instruments are a trend; they can reduce the workload associated with quality inspection and also facilitate early industrial adjustments. If it’s possible, go for it; that’s how things are on our end.
We have CO2 and CO; since the frequency of sample testing is low on a regular basis, online monitoring of sample data can be used
It’s not necessary to do that; online monitoring of hydrogen purity will suffice.
At least for the previous CO model, CO and CO2 can be monitored simultaneously using one device.
It is recommended to use an online chromatograph to analyze CO and CO2, which facilitates timely operational adjustments
There’s no real need for it; one analysis per class is sufficient
There’s no real need for it; one analysis per class is sufficient
Some configurations that are simple involve using a CO online analyzer – that is, to detect the components that are most easily penetrable~~
There’s no need for that; the purity of the new hydrogen is sufficient. CO and CO2 can be analyzed in the laboratory on a daily basis.
