ISO16332 – Filtech 2016
ISO16332 – Oil / Water separators
A while ago, I wrote a blog “Characterizing filter efficiency in diesel engines – ISO16332” about a cell we were designing to meet the challenges of new filters in filter efficiency testing. This has now been successfully launched and has quite a few installs at different customer sites.
The key features were a straight pass through system (no bends which could cause shearing) and a unique design which couples a narrow path length with optimization of the flow within the cell to meet the high concentrations that this application generates.
Read our new white paper on “Assessing fuel filter efficiency using online laser diffraction“. This white paper examines how laser diffraction particle sizing, already an established tool in fuel filter testing, is stepping up to the challenges posed by modern fuels and the latest testing requirements. We consider the technique’s application within the context of the new methods being written for ISO16332, focusing on its implementation for measurements at high concentration, high pressure, and high flow rates.
Filtech 2016 – 11-13th October 2016 – Germany
We are giving a presentation on this new cell at the exciting Filtech 2016 conference in Cologne in a session on Fuel Filtration – analysis and efficiency.
Session: L20 – Fuel Filtration III – Analysis and Efficiency Testing
Day: 13 October 2016
Time: 14:45 – 16:00 h
Improvements in implementation of laser diffraction droplet characterization methods for water emulsions in diesel fuels
Increasing amount of testing is being performed to optimize the efficiency of oil / water separators in diesel engines.
Large water droplets are reasonably easy to remove, but increasingly the water droplets are present in the form of a fine emulsion. The recent addition of various fuel additives (especially in low sulphur diesels) act as surfactants and have the unwanted side effect of reducing the emulsion droplet size and are making the emulsions increasingly stable due to the charge the additives impart to the droplets. As part of filter design, filters must be tested to examine how they will behave in field. New test methods are being written, but they present unique challenges to the laboratory sizing methods required as they present a high concentration, high pressure, high flow sample into a technique which normally has samples diluted, is at atmospheric pressure and often has curves in then flow cell design.
To improve and streamline integration of DSD analytical tools to allow simpler measurements in line with recent changes in standardization and the changing nature of the fuels tested…
There’s a number of interesting papers and I’m sure it’s going to be a really good conference and networking session, and I’m very much looking forward to presenting.
