Process for the extraction of the first and second pressings of oil by means of a horizontal centrifugal separator and separator therefor

摘要

Process for the extraction of the first and second pressings of oil from oil-bearing mixtures, comprising the steps of separating out the various liquid and solid components of the said mixture by centrifugal separation in a horizontal-axis centrifuge comprising the following steps: - feeding the product to the horizontal centrifugal separator; - centrifuging; - retaining the lightest liquid component in the axial direction by radial means; - extracting the axially retained lightest liquid component in an axial direction to form the first pressing of oil; and - extracting another quantity of lightest liquid component in an essentially radial direction to form a second pressing of oil IMAGE
