簡介：Prosep公司研發的ProSalt系統利用一個法蘭連接的設備來代替傳統的靜止混合器，新設備的主要部件是一個內嵌式注射/混合裝置，它能產生均勻的流態，使液體以一種流態流過管線的截面，并且比靜止混合器的差壓小得多，同時對剪切力的控制也增強了。結果是，可分離的水珠分布的更均勻，減少了乳化液的形成，提高了油水分離的效果。該系統同時提升了處理能力，減少了淡水的使用，降低了安裝費用。
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.
