摘要
介绍了脱钙剂在原油电脱盐工艺中的脱钙原理。在DPY-2B电脱盐试验仪上对原油脱钙剂进行了实验性能研究,考察了停留时间、反应温度、脱钙剂用量及注水量对钙脱除效果的影响。结果表明,在停留时间为30 min、温度为120℃、剂钙比(脱钙剂与原油中的钙物质的量比)为1.5∶1、注水量为10%的条件下,钙的脱出率大于90%。
The demetalizing mechanism of demetalizer in electric desalting of crude oil was presented.The perfomance of demetallization agent for crude oil was studied in the laboratory.The effect of mixing intensity,residence time,reaction temperature,and agent/metal molar ratio on metals removal was investigated.The results showed that under the conditions of an agent/metal molar ratio in the range of 1.5∶1,a treating temperature of 120℃,a residence time of 30 min,a affusion of 10%,the removal rates of calcium,iron and nickel were 90%.
