Can online analysis be added to a methanol distillation system?
Thread Content
As is well known, a testing station is always set up in the distillation section to periodically analyze product quality, such as water content, pH level, exposure time, density, ethanol acetate content, and so on. Could an online automatic analysis system be added? This would eliminate the need for manual testing and ensure the safety of the operators... Those who have seen such systems please share their experiences
Theoretically, it’s possible, but with the current level of testing technology, such requirements cannot be met yet!
The theory is okay, but the cost might be too high
Online analysis has not yet been successfully applied in precision coating systems; it requires joint development by instrument manufacturers and product producers, and represents a promising direction for advancement.
For the ethanol content in pure methanol, there are online analyzers available. Hebei Jiantao is being installed online. It works very well.
There are online analytical instruments, but the cost is simply too high
I was wondering which family is using it; how about having a talk?
It would be great if it’s available; if the cost is reasonable, it will be very useful for our operations after installation. In this way, the quality of pure methanol can be directly controlled; there is no need to wait until a problem arises and then have a lab analyst conduct tests. Once the results are available, the methanol that has been mixed with impure substances in the storage tank must be re-rectified. With online analysis, it is possible to detect defective products and switch them directly to the large tanks, thereby reducing costs relatively.
I don’t think it’s necessary. On the one hand, the quality requirements for methanol aren’t that high, and regular analysis is sufficient to meet the needs. On the other hand, as mentioned above, online analysis of liquids is too expensive, so factory owners generally won’t invest in it
The most commonly used parameter for online analysis is currently pH! There are very few others! If there’s online analysis! Then the analysis work isn’t much easier!
Hehe, if online analysis only involves measuring the pH value, then it’s completely unnecessary; the operator can simply carry test strips during inspections. While analysis instruments are convenient, their cost efficiency must also be taken into consideration
pH value and moisture analysis are the most common and important; it is hoped that online analysis can be added
