南美马瑞油、波斯坎油等重质原油具有高密度高含盐量的特点，给原油脱盐脱水带来很大难度，进而对装置造成腐蚀风险并影响正常运行。通过采取一级立式-两级卧式电脱盐罐组合工艺，使用专用的重油高效破乳脱盐剂，以及优化电脱盐运行条件等措施，可将南美重质高含盐原油脱盐率达到90%以上，脱后含水可降至0.1%以内，取得了较好的效果。

South America heavy crude oil such as Merry and Boscan has the characteristics of high density high salt content .These reasons caused crude oil desalting and dewatering is very difficult, will bring device corrosion risk, and affect the normal operation. By adopting the one vertica-two horizontal electric desalting tank combination process,using the special heavy-oil efficient demulsification desalter,and improving the heat transfer process measures to optimize the operation of the electric desalting conditions,can make the South American crude oil desalting rate of more than 90%, water can be reduced to less than 0.1%. Good results have been achieved.
