摘　　要：扬子石油化工股份有限公司泰州石化有限责任公司针对常减压蒸馏装置直馏柴油酸值较高的问题,采用醇碱法对直馏柴油进行脱酸。该技术应用后,柴油脱酸效果良好,柴油乳化问题完全消除,柴油酸度(KOH)从22.01 mg/(100 mL)降至0.8 mg/(100 mL),碱渣中油质量分数从10%降至2%左右。To solve the problems of high acidity of straight-run diesel from atmospheric-vacuum distillation unit in Taizhou Petrochemical Co. , Ltd. , ethanol-deacidification process was applied to remove the acid from diesel. After application, the acidity of diesel was greatly reduced and no diesel emulsification was found. The diesel acidity was lowered from 22.01mg/（ 100 mL） to 0.8 mg/（100 mL）, and the oil in caustic sludge was reduced to about 2 wt% from 10 wt%.
