How to increase the production of crude benzene?
Thread Content
How to increase the production of crude benzene, reduce the consumption of washing oil, and maintain the quality of the washing oil? What is the most reasonable level for indicator control?
Control of gas temperature in the benzene washing tower. Oil washing quality. Debenzene tower temperature control ； Oil-rich temperature ； Oil washing and slag formation process.
Same as above; it seems necessary to keep the lean-burn temperature under control as well.
It is mainly about controlling the temperature and understanding the boiling point
Could the teachers upstairs please be more specific? What are the desired temperatures for the gas and the lean fuel condition?
I agree with the view from the 4th floor: the lower the temperature, the better for absorption. Considering the viscosity and flowability of the oil used for washing, a temperature of 25°C is generally suitable for absorption.
It is mainly the control of gas temperature and lean oil temperature. Minimize the reflux ratio as much as possible while maintaining acceptable quality
The gas temperature is 24-25 degrees; the temperature of the lean fuel mixture cannot be reduced – it is currently at 33 degrees. The rich fuel mixture has a temperature of 170-175 degrees, the superheated steam temperature is 330 degrees, and the temperature at the top of the benzene removal tower is 95-96 degrees.
The gas temperature is 19–22°C; the oil-poor phase temperature is 1–3°C higher than that of the gas, while the oil-rich phase temperature is 185±5°C. The top temperature of the benzene removal tower is 89–91°C. The mass of circulating oil is such that the amount distilled before 270°C exceeds 70%, and the regenerator discharges slag.
