A few days ago, the first online desalting system of Jinan Refinery and Chemical Company was put into use in the 1.
4 million tons/year heavy oil catalytic cracking unit.
After optimization and adjustment, it can effectively reduce the risk of salt formation and corrosion of the equipment and ensure the safe, stable and long-term operation of the device.
.
The online desalination system has a simple process, is easy to transform, has less investment and low energy consumption.
After repeated operation adjustment and data monitoring and analysis, the salt impurities in the circulating oil at the top of the fractionation tower are well removed, which solves the problem of online salt washing in the previous fractionation tower.
Problems such as complex operation, large amount of slop oil and sewage, and production fluctuation caused by the reduction of equipment have improved the safety, stability and economy of the operation of the overhead circulation system of the fractionation tower
