重油催化裂化油浆二级过滤技术的应用
Application of two-stage filtering technology for heavy oil FCC slurry
摘要
Abstract
Utilization of RFCC slurry oil has been limited by the content of solid impurity. How to resolve this problem is critical for subsequent production. Considering domestic catalytic slurry oil, Jinzhou Design Institute adopted the unique two-stage filtering technology of Pinfu Co.Ltd, and the majority of solid particles and asphaltene could be filtered by the first-stage filter. For the second-stage filter, metal powder-sintered filter elements with surface coating greatly improved opening efficiency and through flow and also the effect of backflush on filter elements. Offline washing of filter elements promised that filter elements could be reused after a work cycle. The content of solid particles in slurry oil after filtering was lower than 0.01 percent, which improved the quality of slurry oil produced.关键词
