【摘要】：介紹了某常減壓蒸餾裝置高速電脫鹽工藝運行狀況,針對進口原油種類、混煉比例變化較為頻繁的工況,優(yōu)化確定電脫鹽混合強度和溫度的操作優(yōu)化區(qū)間,確定反相破乳劑和增脫劑的投加量。結果表明,當一級進口和二級進口的混合壓差控制為50 k Pa和60 k Pa、電脫鹽溫度控制在125℃、反相破乳劑投加量35μg/g、增脫劑投加量40.5μg/g時,脫前鹽含量下降至15.68 mg/L,脫后原油平均值下降至1.84 mg/L,脫除率91.5%,含鹽3 mg/L合格率100%、2 mg/L以下為74.24%,金屬離子下降74.8%,裝置腐蝕控制良好,外排污水達到環(huán)保指標要求。
[Abstract]:The operation status of high speed electric desalination process in an atmospheric and vacuum distillation unit is introduced. according to the types of imported crude oil and the frequent variation of mixing ratio, the operation optimization range of electric desalination mixing strength and temperature is optimized, and the dosage of inverse demulsifier and demulsifier is determined. The results show that when the mixed pressure difference between primary and secondary imports is controlled at 125 鈩，
