Oil washing processing
Thread Content
In recent years, the processing of coal tar in our country has developed rapidly; initial processing has reached a certain scale, and now efforts are being made to advance toward more refined processing methods. Let’s exchange ideas on the progress of oil washing processing.
The technology is well-developed, ready for further progress
We installed a 30,000-ton unit; two continuous distillation systems have been operating successfully
It seems that continuous distillation can yield a product with over 97% purity? I would appreciate your guidance
We also installed a set of equipment for oil washing processing back then, but due to the poor market conditions for methylnaphthalene, it was shut down after operating for a while; it was a setup designed to produce methylnaphthalene and dimethylnaphthalene from washed oil
The deep processing technology for washing oil has been matured. It’s mainly because market conditions are poor and there’s no profit to be made.
