Ejector Systems for Fats, Oils, OleochemicalsOpen File / 786.49 kB
Description: Essential processes in the production of natural fats and oils and derivative oleochemicals are performed under vacuum, i.e., at a pressure below atmospheric. Such processes, including solvent extraction, degumming, bleaching, interesterification, fractionation, winterization and deodorization, are supported by ejector systems

Options Analysis of Vacuum Columns and Ejector SystemsOpen File / 93.44 kB
Description: This paper attempts to show the effects on an ejector system when various operating parameters are modified in order to improve vacuum column cut point. Ejector system design is directly impacted by cut point set for the atmospheric column that precedes a vacuum column. It is noted that increasing cut point for the atmospheric column results in added stripping steam to the vacuum column, consequently, a larger ejector system is required.
