A method for preparing and using an MTO device waste caustic oil-water separation agent
By using an oil-water separator composed of benzaldehyde and quinoxaline compounds in the MTO unit, the interfacial film in the waste alkali liquid is destroyed, achieving oil-water separation. This solves the problem of grease emulsification in the waste alkali liquid, ensures stable operation of the unit, and reduces the risk of equipment blockage.

AI Technical Summary
The butter emulsion in the waste alkaline solution of the MTO unit is difficult to separate, leading to equipment blockage. Existing technologies such as air flotation and membrane separation are inefficient or costly, while chemical methods are not targeted enough and cannot adapt to the conditions of strong alkalinity, high emulsification and high oil content.
An oil-water separator composed of benzaldehyde and quinoxaline compounds is used to achieve efficient separation of the oil and water phases by disrupting the oil-alkali phase interface film. The demulsification effect is enhanced by multi-point continuous injection, which is suitable for the operating conditions of MTO units.
It achieves rapid demulsification and clear separation of waste alkaline solution, reduces the risk of equipment blockage, ensures long-term stable operation of MTO unit, and has no secondary pollution, low cost, and strong adaptability to operating conditions.
