Martin: What can we do proactively to avoid the problem? That really comes back to what we said right at the beginning: Stop stressing your oil. Avoid the water, the heat, the air, and the metals. If you have actually got varnish already, you’re going to be reactive at removing that, and there are techniques such as balance charge agglomeration that will attempt to draw the very, very fine material out the oil and similarly uh electrostatic filtration.
In that we’re using an electrostatic effect to draw the very, very fine material out because we are talking, you know, oxidized oil molecules of less than a micron in size so clearly your standard filtration doesn’t always deal with that particularly well, in fact it can actually choke up your standard filters but it’s not removing it necessarily from the oil. Rather that’s akin to say pouring a bag of sand into a drain it can choke the drain but it’s not going to stop all the sand however some filtration units and, I hesitate to mention brand names, but for example offline filtration units there’s a Danish company CC Jensen that actually do large disks of cellulose in an offline format and because of the slow flow of the oil through the cellulose medium it is actually very, very effective they’ve done research showing that they can pull quite a bit of the oxidized material out the oil and the problem is proving it because with your iso 4406 cleanliness codes and your SAE 405 9 stroke the beloved national aerospace standard 1638 of the oil and gas industry, they focus on the much bigger particles greater than four micron and so clearly you could have an extremely clean result and I’ve seen this where filters blocking up and we’ve got clean results so clean that you begin to wonder why we’re even bothering with filtration almost but you know the thing is that obviously we’re not detecting the actual oxidized oil molecule because it’s less than a micron so things like gravimetric sampling MPC, even just the colour of the oil so you know you’ve got the technique working well when your oil can go back to a nice clear bright colour and that’s where also resin filtration again resin filtration is a kind of form of polar medium which will draw the polar material out the oil and obviously bring it back to a standard that would be deemed acceptable for use, okay, so as I say obviously ultimately fight the WHAM; the water, the heat, the air, the metals. Look after the oil, look after the oil and the oil will look after.
Haris: We deal with that problem in the Mediterranean area for thousands of years you know so you have to be careful when you consume olive oil, you have to use high quality olive oil you have to always use garlic as an additive and then you also drink aceto balsamico which is very good for removing cholesterol and then you don’t get the varnish in your bloodstream.
Martin: Let me guess; in a previous life you were Getafix the druid from the asterisk stories.
Haris: Yes exactly. I always like to drive this this kind of parallel because dealing with assets is really like a medicine and what primary medicine doctor tells you; don’t do this, don’t do that, take care about this … is actually key to avoid surgeon in the end. And I recognize all this, in what you just said.
Martin: Great, very short six minutes with all my wisdom dumped on you then.
Haris: Yes, but you know I call it six Turkish minutes.
Martin: Oh, OK, fair enough.
Haris: Because they’re just a little bit longer.
Martin: okay
Haris: Thank you for this session Martin, thank you for the session it was really great. I hope our friend will be happy with answer and there will be next answer coming next Monday, next question coming next Monday and certainly the answer.
Martin: Are we moving on from varnish to paint next week?
Haris: Yes, yes, so we go in layers.
Martin: I love do-it-yourself activities around the house.
Haris: Yes exactly, thanks a lot and see you next week.
Martin: Great, goodbye, take care
