简介：Prosep公司研发的ProSalt系统利用一个法兰连接的设备来代替传统的静止混合器，新设备的主要部件是一个内嵌式注射/混合装置，它能产生均匀的流态，使液体以一种流态流过管线的截面，并且比静止混合器的差压小得多，同时对剪切力的控制也增强了。结果是，可分离的水珠分布的更均匀，减少了乳化液的形成，提高了油水分离的效果。该系统同时提升了处理能力，减少了淡水的使用，降低了安装费用。 

The compact one-shot ProSalt mixer system combines the fresh water injection and crude - fresh water mixing by imposing a homogeneous shear stress of the dispersed fresh - crude flow. As a result a homogeneous fresh water droplet size distribution results, resulting in a more separable fresh water - crude mixture and correspondingly better utilisation of the injected fresh water. The ProSalt, equipped with actuator driven mixer cylinder internal, can handle any turn-down crude flow rate.

For the conventional desalting process of crude, static mixers, such as globe valves, have been used for mixing of crude with injected fresh water. This mixing method often results in consuming high quantities of wash water and chemicals with relatively low mixing efficiency. The static mixer pressure drop represent a considerable pressure drop and risk for poor crude - fresh water separation in the downstream separator.
