美国海湾石油公司早先推出静电分离器用以澄清催化裂化抽浆,这种静电分离器包括油浆澄清管、变压器和程序控制器构成组合单元,可使油浆中固体杂质含量降到10～500ppm 以下。但这种设备构成较复杂。近年又开发推出了一些简单易行的过滤器设备:1.盘式过滤器美国温库(Vacoo)工业公司开发的净化催化裂化汕浆的蚀刻盘式过滤器(Etch-ed Disc Filters)已在三座大型炼油厂催化裂化装置上应用.处理油浆杂质范围为2500～100ppm.在压力高达6865kPa、温
United States Gulf Oil previously introduced electrostatic separator to clarify the catalytic cracking pumped pulp, the electrostatic separator, including slurry clarifier, transformer and the program controller constitute a combination of units, the slurry can be solid impurities reduced to 10 ~ 500ppm or less . However, this device is more complicated. In recent years, it has also developed some simple and easy-to-use filter devices: 1. Disc filter Etch-ed Disc Filters developed by Vacoo Industrial Co., Ltd. Three large-scale oil refinery catalytic cracking unit on the application. Treatment of slurry impurities range of 2500 ~ 100ppm. At pressures up to 6865kPa, temperature
