Abstract:
     The invention disclose a crude oil desalting method and device using rotational flow breakaway technology, wherein the method consists of, isolating the primary oil with charged water and demulsifying agent into oil phase and oil-contaminated water at 100-300 deg. C, isolating the oil phase through sedimentation by precipitation tank, entering downstream unit, charging the dirty oil into dirty oil tank, and discharging the salt-containing sewage water. One stage, two stage or multiple stage cyclone desalting unit can be utilized based on the requirement.
