@pangea I like what you’re thinking.
If you fill the horizontal 8x48 up to 6" there won’t be much headspace in there so you’ll probably need a liquid/vapor separator in the recovery path. For reference, I run propane with a Corken on a 12" wide collection pot and usually have a solid 4-6" of frothy bubbles on top of the liquid level during peak recovery. I like to have a lot of extra headspace in my collection pot, don’t you think you’re cutting it a bit close and increasing the chances of sucking solution into the recovery path?
It sounds like you’re thinking about doing the full recovery in the 8x48’s. If that’s correct what are you thinking about doing when it’s time to harvest the oil out of it? Seems like it could get a little messy and time consuming with the horizontal orientation (have to stick your arm in there 24"). I have seen funny pictures of guys having to reach in wearing those full arm-length gloves. I think I saw one with the guy’s arm wrapped in saran wrap or something. Terrible, lol.
Have you considered using a horizontal vessel as a “breaking chamber” designed to quickly recover the bulk of the solvent but then transfer to a smaller “honey pot” to recover the last bit? Maybe a small vertical 8-10" wide jacketed vessel or something simple like that? I think it would be much easier to collect the oil that way and then use fresh warm solvent to CIP the horizontal chamber when needed.
I’m pretty sure that’s what concentrated_humbold does and I’ve read through the Bhogart info, that’s what they do as well. It’s not a bad idea, depending on your throughput. I’ve always wanted to setup a large system and use a kettle reboiler as the breaking chamber.
Sounds like a good idea to me. I think this will really help boost recovery significantly and should be pretty easy to implement on a rack mounted system. Haha, enthalpy booster is such a great name, big thanks to Bizzy for that one.
For some reason my brain likes a tube-in-tube design better for this job. With tube-in-shell I always worry about having to come up with a way to evenly distribute the flow to all the tubes. You don’t need to deal with that on a tube-in-tube.
Remember how Bizzy had three of the Exergy tube-in-tubes tilted on their side and connected in series to boost enthalpy of ethanol solution prior to his FFE? I liked that a lot.
