Why should the oil-poor temperature in the washing benzene tower be higher than the gas temperature? Please ask a Haiyou to answer.
To prevent water in the gas from condensing into the washing oil, increase the pressure of the tubular furnace during distillation. Additionally, the water content in the washing oil causes it to emulsify. The absorption efficiency decreases.
This is the principle of diffusion. A high oil deficiency temperature increases the vapor pressure on the oil-washing side of the oil-gas interface, causing water in the oil wash to diffuse into the gas. As mentioned on the second floor below
Having water in the washing oil can lead to serious consequences, causing instability in the system.
