Quality requirements for the washing oil in the benzene washing tower
Thread Content
What properties should the washing oil possess to meet the requirements for absorbing and producing crude benzene from gas? 1. It has a good absorption capacity for aromatic hydrocarbons at room temperature, and can be effectively separated from crude benzene when heated during distillation ； 2. It has sufficient chemical stability, meaning that its absorption capacity remains essentially unchanged after long-term cyclic use ； 3. At the operating temperature for the recovery of crude benzene, no solid precipitates should form to avoid clogging of equipment and pipelines ； 4. Does not form an emulsion with water, and is easy to separate from water ； 5. It has good fluidity and dispersibility, enabling the washing oil to be easily transported and distributed evenly over the packing in the benzene washing tower ； 6. The initial distillation point of the washing oil should be high enough to prevent excessive consumption during distillation. What other requirements are there?
The density and viscosity of the cleaning oil should be appropriate to ensure adequate contact with the benzene derivatives in the gas without causing excessive resistance. Furthermore, the washing oil should have good thermal stability to withstand the high temperatures that may occur during distillation. Attention should also be paid to the corrosion-resistant properties of the cleaning oil during storage and reuse, in order to prevent equipment damage. .
