Cold potassium glyc wash?

[julianf]

I have an IBC where i store my incoming (soon to change, but in the mean time...)


If i chuck a load of cold potassium glyc in the top, and then pump it arround (cold) with my mono, will there be any benefit?

I cant think there will be much mixing really?  The mono is probably the only pump i have that will pump cold glyc, and i dont really want to introduce back pressure to it (sprays etc)

So, i think its probably a bad idea, but id be interested to know if anyone thinks otherwise?

There will be a benefit, but the drawback is that the glyc will take a long time to separate. Most will drop in a few days but a lot will take probably weeks at ambient outside temps at this time of year.

Flat bottom tanks arn't good at separating.

Although the Mono will pump the glycerin, it's probably the worst pump you could choose for mixing!

I remember tipping all my warm glycerol into my IBC oil storage several years ago. It was about this time of year. At the time the oil in the tank was about 25% palm. I mixed it up with the big jabsco pump.
Something like the following February when I emptied the tank into 'a lot' of cubies the glycerol was still in suspension!

The next summer I had the tank in my polytunnel (daytime temps 30 to 40degs) I would keep about 300 litres of glyc in it under up to 700 litres of oil. When I had more glyc to put in I would run some off from the bottom tap. I had a higher tap set at about 450 litres for the oil. That system worked well but now I've got the M67 set up under the hay barn that works much better.
