Background
The mechanism of the demulsifier is a reverse deformation mechanism of phase transfer, and after the demulsifier is added, the phase conversion is carried out, namely, a surfactant with the opposite type of emulsion formed by the emulsifier can be generated, and the demulsifier and the hydrophobic emulsifier act to generate a complex, so that the emulsifier loses the emulsifying property, and a special crude oil demulsifier is generally used for destroying the emulsifier on the surface of the crude oil during the processing of the crude oil, thereby meeting the requirement of post production.
At present, most of the way of manufacturing demulsifiers mixes clear water and demulsifiers, however, clear water and demulsifiers easily generate a large amount of foam in the process of mixing and stirring, and the foam can generate certain waste to raw materials and is unfavorable for accurately metering the demulsifiers, so that the clear water and demulsifiers are generally led into a defoaming tank for defoaming treatment, and the defoaming tank is subjected to chemical dosing treatment, in particular, the prepared defoaming agent is directly added into the defoaming tank for defoaming treatment, however, after the defoaming agent is injected into the defoaming tank by using a pipeline, the defoaming agent is not easy to disperse, so that the defoaming effect is poor.
