the x spiral is @MagisterChemist work, I’m guessing this is a white label deal
I have gotten messages telling me to avoid this like the plague.
Guess I’m sticking with the @Lightbulb pig filter
This particular unit is just an X-spiral painted orange at his request. Sold some 2-3 years ago, I don’t think it was ever turned on – I certainly was never called out to commission or train on it.
They haven’t sold a white label unit from me for years, and the current systems they’re selling are made by other people.
It doesn’t perform the same tasks as as PIG filter, so that’s like comparing a rotavap to a centrifuge - buying one in no way affects whether the other one is useful or not. If my memory survives (for a 2-3 year old system that was never turned on), this was sold for solvent recovery, which is not something a PIG filter does.
It winterizes things?
I’m sorry I didn’t state I would keep using my pig filter and roto.
But I was advised this didn’t work very well for winterizing things.
I think it would be dewaxing rather than winterizing, but I have no idea.
I seem to recall that trying to winterize using a membrane spec’ed for solvent recovery (and vice versa) wasn’t a win…
Pretty sure @MagisterChemist was in the room when we figured out that was the problem too.
Right @Lincoln20XX?
That sounds about right to me.
A solvent recovery membrane will probably do exactly that. Solvent goes through, noids and other heavier crap stay back.
And if you’ve got unwinterized crap on the feed side, you’re going to have a slow and terrible time of it.
A dewaxing/winterizing membrane should let the noids and solvent through and keep the fats and waxes and stuff back.
I will say that at the current price, that looks like a steal of a deal to me. Anything 20k and below is probably less than most would be able to put one together for, without including the nice frame or paying for your time etc.
Swapping to different membranes would be easy, though I don’t see a heat exchanger anywhere on there so keeping the process cool to cold for dewax might require a tiny sliver of cleverness.
