It is recommended that the landlord can do experiments, use the crystallization method, use the freezing points of different materials, and try to separate. Since there is no public reporting similar separation technology, it means that it is a blank or technical confidentiality that it needs to be developed.Maybe there are new breakthroughs!

The idea of the 3rd floor is unique, whether success or not, the idea is good.learned.If you need to cool the crystal separation, I can help to test. 3# ysd168

There are many ways to separate, but according to the current technical data, Celarinis no longer has to reorganize the tower, that is, no propionate in acetic acid. The main reason is that its propionic acid content is lowIn 100ppm, there is no need to separate; may be because has high purity of the ingredients, low ethanol content in methanol, and high selectivity of catalysts
Any separation measures will only increase energy consumption and acetic acid cost costTo compete in the brutal acetic acid market at this stage, it is not only necessary to rely on quality, but also rely on technology to improve quality.

Personally think that the effect of the distillation is not too great. After all, the difference between the two boiling points is not too large, and the situation of co -boiling is not clear

The treatment center designated by the Environmental Protection Bureau is close to 3,000 yuan per ton, mainly because there is no black smoke when burning, and there is a sour smell and strict environmental protection inspection.

The pyrine -based synthesis process with propionic acid has been out of date. By adjusting the methane content in the synthetic gas, the acetic acid produced is almost excluding propionic acid.We used to be separated through the distillation. The upper two towers, one thick division, and the other distillation is relatively simple. It is high energy consumption. Now the price of acetic acid is not good.Anyway, it is not worth a little money!IntersectionIntersection

The original poster, is it still there? Is this problem solved? I have encountered this problem now. I want to communicate with you. There is a certain amount of macromolecules and glue substances. If a lot of accumulation is accumulatedWill block the device, what do you deal with!

The colloidal substance in the tower kettle is a high -boiling point mixture, so it has to be discharged as a dangerous solid waste burning. It is quite expensive. There is no way.

Propionic acid is a chemical product without market value, and the amount is too small.
I think the landlord should start from the source to control the purity of the inlet methanol to minimize the content of ethanol impurities, so that the propionic acid generated will be reduced. The separation of propionic acid and acetic acid, I personally think that it is still refined, after all, the method of mature.It is difficult to use frozen separation, which requires low -temperature equipment. It is difficult to operate and maintain.

The distillation separation is performed, and some salt substances will be contained in the tower kettle, which is separated by cooling and crystallization to further increase the level of propionic acid.
