500 lt tank as a Processor

I get the butler to do that

"The Master? Why yes, he's in the batcave making biodiesel at the moment, can you wait?"

Keith, could you run some kind of acid through the processor, to remove the rust? Not sure what, but maybe a weak solution of sulphuric? just an idea.

[K.H]

If it keeps up i will have to do something like that,i should of blasted it when i had the chance

[Tony]

Presumably the rust doesn't cause any problems though?  Most of it must go with the glyc and the rest get washed out by your finishing process?

Even though I don't water wash I can't see it staying in suspension during the settling process, if not drywash + 1u filtering would sort the rest.

Besides, those of us with vehicles going on for a couple of decades old are quite familiar with in-tank rust

[K.H]

Yes most goes out with the glyc,the rest in the wash,the two final filter show no contamination but i just dont like the idea of it been there just in case

[Tony]

I wouldn't worry, after all the masses that visit fuel stations pump their fuel out of rusty steel tanks buried beneath the forecourts... that's why they say you shouldn't fill you car right after the tanker has visited, as all the water/rust sediment has been stirred up by the tanker delivery. Not that I'd remember how to operate a forecourt pump these days

I wouldn't worry about a swept bend before the eductor,
the pipe diameter will be reduced at the eductor anyway, so a standard 90° will not effect the flow rate.

My eductor feed is 22mm (the rest of my pipework is 28mm) the eductor nozzle is 15mm so that's still the most restrictive part.

Does my eductor still work ? Well it makes the whole reactor shake whereas if I'm running the venturi is steady as a rock,
so yes I'm sure it's still working.
