Crude benzene quality
Thread Content
What are the reasons for the high contents of bing, yttrium, and rare elements in crude benzene? What are the reasons for the low benzene purity in crude benzene?
It’s been 7 days since the post was sent – why is there no reply? Does no one know, or do they simply dismiss it?
Some people say that it is due to inadequate treatment of gas before benzene washing, poor ammonia washing efficiency, incomplete desulfurization of the gas, or no desulfurization at all. Is this claim correct? Will a high temperature at the top of the benzene removal tower cause a decrease in the purity of benzene? I would appreciate some guidance from an expert.

How is it possible that the benzene purity in crude benzene is low? Is the content in the gas lower? A high temperature at the top of the benzene removal tower should not affect the purity of benzene. Benzene can volatilize at very low temperatures, and the temperature at which the light-rich oil begins to vaporize is already 180 degrees; therefore, benzene can definitely volatilize.
A high temperature at the top of the benzene removal tower causes the light components in the washing oil to end up in the product, resulting in a reduced boiling range of the crude benzene and a decline in the quality of the washing oil
The benzene content in coal gas varies depending on the type of coal
Changes in the heating method and adjustments to the operating procedures can all have an impact.
