The product is a multi-functional composite additive based on the mechanism of scaling formation in hydrocracking of crude oil , with the small amount of product being put in up-stream of converter or reactor before crude oil being fed in, so as to refrain the heat exchanger or reactor from scaling formation, even to eliminate some of the established scales. Therefore, it can significantly reduce the plant power consumption, by extending the operating cycle and reduce maintenance costs. Moreover, it has no harmful effect on follow-up hydrogenation catalyst and product distribution. The product also shows a good performance of oil solubility, moderate viscosity and easy application, etc.Information provided by Jilin Xingyun Chemical Co., Ltd. |
