摘　　要：工业试验研究了RPD Ⅱ型脱钙剂的脱钙效果及其对电脱盐系统操作性能的影响。改进后的RPD Ⅱ型脱钙剂具有良好的效果 ,在剂钙质量比大于 3 .5时 ,对平均含钙 5 4μg/g的原油 ,脱钙率在 90 %以上 ,原油中钙质量分数可降至 5 μg/g以下 ,对灰分的脱除率在 80 %以上 ,对铁的脱除率最高达 74.1%。加入该脱钙剂后 ,电脱盐罐中电场电流大幅度下降 ,电压增大 ,改善了电脱盐系统的操作性能 ;电脱盐排水中油含量降至 10 0mg/L以下 ,达到炼油企业电脱盐排水油含量不大于 2 0 0mg/L的指标要求 ;对电脱盐装置无明显腐蚀。Decalcification effect of RPD-Ⅱ type de-calcification agent and its influence on electric desalting operation system have been researched by commercial test and the result shows that the improved RPD-Ⅱ de-calcification agent has an excellent decalcification effect. When the agent/calcium ratio is large than 3.5, de-calcification rate is over 90%, for the crude oil whose average calcium content is 54 μg/g. The calcium content in crude oil has been reduced below 5 μg/g, ash removal rate is over 80% and the highest iron removal rate is 74.1%. When RPD-Ⅱ de-calcification agent was added, electric field current of the desalter has been greatly reduced and the electric pressure increased, so the operation performance of the electric desalting system has been improved. Oil content in the effluent water has been decreased below 100 mg/L and the target requirement of 200 mg/L for oil refining enterprise has been met.
