High benzene content behind the tower
Thread Content
After the renovation of the benzene removal tower in our plant, the lower heat-poor oil tank was removed, increasing the space at the bottom of the tower by over 6 meters. Currently, the temperature of the gas inlet is 30 degrees; the oil content is low with a benzene level of 0.2~0.3. What is the benzene level after the tower? 4~5?
Is it because the gas inlet temperature is high?
The first floor refers to the benzene washing tower, right? The lower part should be the oil-rich tank, I guess
Reply to 1# sxszsbj: The temperature of the imported gas should be maintained between 25–26°, while the temperature of the absorption oil should be kept between 27–29°； It is also easy to control the liquid-to-gas ratio–by increasing it.
Bro, you’re referring to the benzene washing tower, right? Judging from the low oil content in your plant’s gas, the benzene removal efficiency is quite good. However, the high benzene content in the gas coming out of the tower could be due to the following reasons: 1. The temperature of the gas entering the tower is high. 2. The quality of the washing oil is poor, with a high relative molecular weight. 3. Insufficient oil-gas contact area and contact time.
Which expert could explain the relationship between benzene content in the coal before it enters the furnace and the coal used in the furnace? Thank you
