Our factory uses waste vegetable oil to produce fatty acids and emulsifiers, and we are now conducting a safety assessment. The leader of the Safety Supervision Bureau said that we fall under the chemical industry category, but we have always been classified as part of the industrial and trade sector Is there anyone who knows this field?

Some emulsifiers belong to the field of fine chemicals

Which are some of the emulsifiers? We are the S80 emulsifier

The leader says it is, and we’re not allowed to say anything! We visited the Provincial Institute of Light Industry and Chemical Engineering; they are involved in light industry, but unfortunately the officials there said it wasn’t possible.

This is still typical bureaucracy; nothing is done. What’s the point of talking about improving work styles if the inspection teams aren’t present?

This needs to be put into operation; are there any areas that haven’t been handled properly?

I want to find the exact documents that prove I work in the industry of trade and manufacturing right now, but unfortunately **the regulations regarding industry classifications are too broad and not specific enough. So I’m asking everyone.

We are in the county town, and the leaders are from the city; it’s completely impossible to establish any connections. Industry and trade, as well as the chemical industry, are under the control of two different leaders, and everyone is competing for power.

A process for producing mixed fatty acid methyl esters from plant oil residues, characterized by comprising the following steps: Dilution: Take the plant oil residues, add water, and heat them ； 　　　　 　Cracking: ZnO, Al2O3, and AlCI3 are added as catalysts, which are then placed in a catalytic cracking furnace where heating is applied to carry out continuous cracking ； 　　　　 Stirred-takeoff hydrolysis: The aforementioned cracked mixture is subjected to steam stirred-takeoff, and the resulting gas mixture is then cooled to separate out the water, thereby obtaining the cracked feed oil ； 　　　 　Esterification: Take the aforementioned cracked feed oil and mix it with methanol and concentrated sulfuric acid, then stir it for 8 to 12 hours at certain temperature and pressure ； 　　　 　Cleaning: Water is added to the esterified mixture, methanol is recovered by heating, and then quicklime is added to carry out a neutralization reaction ； 　　　 　Distillation: The cleaned residual mixture is placed under specific pressure and temperature for distillation, thereby yielding mixed fatty acid methyl esters. Distillation: The cleaned residual mixture is placed under certain pressure and temperature for distillation.
