Producing hydrogen from 100 cubic meters of methanol: the liquid level in the vaporizer is unstable; seeking help
Thread Content
I am producing hydrogen from 100 cubic meters of methanol; the liquid level in the vaporizer is unstable. The temperature of the heat transfer oil is normal, and water supply to the plunger pump is also normal. However, the liquid level in the vaporizer suddenly rises or drops 1-2 times a day. I seek advice on this issue. Thank you.
Are your system pressure and vaporization rate stable? Check whether the vaporization rate increases suddenly when the liquid level in the carburetor rises. If the vaporization rate increases while the temperature of the heat transfer oil remains stable, then examine the feed plunger pump.
The system pressure is between 1.1 MPa and 1.2 MPa; when the liquid level in the carburetor rises, the amount of vaporization increases suddenly, after which the liquid level in the carburetor drops. The temperature of the heat transfer oil remains constant, which means the problem is likely caused by the plunger pump not being able to draw in liquid properly
