| Abstract: | Taking the 500 kt/a atmospheric distillation unit of a petrochemical enterprise in Yangzhou area as a research object, an ultrasonic electric desalination technology was used to replace conventional demulsifier - electric desalination. After 1 month, the average value of the salt concentration from the second desalination stage is decreased from 2.42 mg/L to 1.67 mg/L, a 30.99% reduction. The total salt removal rate is increased from 91.74% to 96.03%. The oil content in wastewater is reduced from 158.9 mg/L to 47.68 mg/L, and COD lowered from 2 845 mg/L to 1 067.5 mg / L. |
