WebThe present invention is an automatic filter cleaning system which includes a solvent dewaxing filter which removes wax from a wax mix slurry and provides a filtrate. Status control apparatus is connected to the filter for affecting the operational status of the filter. Drain apparatus responsive to a control signal controls draining of the filter. Webfilter cake forming on the surface of a filter becomes impermeable and blocks the filter (Figure 1, right). Adding highly porous DE creates a more permeable filter cake, which prevents blockage (Figure 1, left). The minimum amount of DE to guarantee smooth filtration depends on the particle concentration. Laboratory- WebDiesel dewaxing technologies offer the best diesel yields, significantly reducing naphtha production and creating unbeatable on-stream stability combined with operating flexibility. ...
