簡(jiǎn)介：Prosep公司研發(fā)的ProSalt系統(tǒng)利用一個(gè)法蘭連接的設(shè)備來(lái)代替?zhèn)鹘y(tǒng)的靜止混合器，新設(shè)備的主要部件是一個(gè)內(nèi)嵌式注射/混合裝置，它能產(chǎn)生均勻的流態(tài)，使液體以一種流態(tài)流過(guò)管線的截面，并且比靜止混合器的差壓小得多，同時(shí)對(duì)剪切力的控制也增強(qiáng)了。結(jié)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(tǒng)同時(shí)提升了處理能力，減少了淡水的使用，降低了安裝費(fèi)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.
