STLE Toronto On-line Technical Meeting Notice: Optimized Liquid/Liquid Coalescence for Improved Water Removal from Hydrocarbon Lubricating Oils: By: John K. Duchowski, Ph.D
Reducing Tribological Losses and Failures – Part 41
STLE TORONTO SECTION – Online
Speaker: John K. Duchowski, Ph.D
Subject: Optimized Liquid/Liquid Coalescence for Improved Water Removal from Hydrocarbon Lubricating Oils
Date: Sep 8th 2026 , 10-11 AM EST
Abstract:
A novel liquid-liquid phase separator with several media layers of alternating hydrophobic, hydrophilic character was assembled and pleated into a cylindrical structure. The cartridge was employed for extraction of water from differently formulated lubricating oils in various applications. Excellent separation efficiencies were observed for the 32 cSt and 46 cSt turbine oils. Most notably, the separator has proven itself highly effective in extracting water from the more viscous 220 cSt and even 460 cSt Morgoils, where water poses a serious operational problem. Examples of both the laboratory results and practical field applications will be described and discussed.
