Continuous solids-discharge disc stack centrifugation has been used in other industries such as brewing for robust removal of solids from process streams (4).Continuous-discharge centrifugation differs from periodic-discharge centrifugation (Figures 1 and 2) in that rather than solids being discharged periodically, they travel …
Filtration in crude oil refining | Cytiva
The refining process. In the final stage of the petroleum processing workflow, oil facilities send processed crude oil to refineries, where petroleum engineers transform it into the final products using fractional distillation. The oil is first heated, then separated into different chemical fractions based on their boiling points.

Filters – Visual Encyclopedia of Chemical Engineering Equipment
A pressure leaf filter is a pressure-driven filter contained inside a pressurized vessel. Here, the slurry is pushed through several plates of filter media, called filter leaves. The solids collect on the filter leaves and the filtrate is recovered. This large pressure leaf filter has a retractable shell.
Getting the Most Out of Your Rupture Disc
(Page 1) Rupture disc devices provide overpressure protection for a variety of storage and process vessels and equipment. The objective of the rupture disc is to maintain a leak-tight seal and be a passive bystander until called upon to relieve excess pressure. While this is generally the case, there are times when rupture disc performance can be …
