Methanol density
Thread Content
In the production processes of fertilizer plants, the density of methanol is relatively important. At present, this value is determined through laboratory tests, which often involve a time lag. So how can online monitoring be achieved? Firstly, it depends on the pressure difference between two points in the pipeline or container, as there is a certain relationship between pressure difference and concentration/density. Secondly, it is necessary to compensate for errors caused by changes in the temperature of the medium and the ambient temperature, in order to ensure the accuracy of the measurement results； It has already been put into use at a chemical manufacturing company in Shandong, and the verification results show that its error rate is less than ±0.002, which is sufficient to meet the requirements of production. What do you experts on this forum think?
Density should also be related to purity.
Could you explain the principle? What are the precautions during actual operation, and under what circumstances will it fail?

When we produce crude alcohols, we only control the purity.

You produce crude methanol; generally, crude methanol is only an intermediate product, while refined methanol is the final product. Moreover, it is very difficult to control the purity of crude methanol
