Still loling at this one…(in relation to cannabis processors, not another industry)

Also, corken doesn’t make a “turbine gas compressor”.
These are their options:

I’ve recovered at 6lbs a min. I’ve recovered at over 10 lbs a min. Neither was pump assisted.

Only good to -32C… Looks like problem number 1, and that’s only a cursory glance

There are many gas compressor designs, each with their own pros and cons. I used a turbine as an example of the huge hydrocarbon industry tech that someone asked for.
Thats great! Show me your design and I bet I can show you how a compressor can save you time.
Wanna comment here on the turbine?
Im not arguing that the fastest system in use in the cannabis industry is active. I really dont know what people are using anymore. Ive been out of the game awhile now. Im saying design any passive system and I can show you how a gas compressor can shorten process time.

People are hitting fucking 6-8+# per minute passive…
Probably faster if you had a Butane falling film…

So I’m not sure if this question has been answered yet but wouldn’t the best of both worlds be passive until the end of recovery and then turn on a tr21 to finish?

Or just use the pump for recovery from the material columns and passive for the rest

Actively passive. Or passively active. Call it what you want, but a harbor freight Vac pump pulling negative pressure on a slurried tank through a slurried coil is the fastest achievable by the laymen that make up the majority of extraction enthusiasts.

Yikes I wouldn’t risk that. Id rather pull a hard vac on the tank via trs21 and push into a secondary hot tank. Although I don’t think the pumps like to run dry. So the best option is the venturi vac that bizzy bee and @Dred_pirate use

That would be the best option. But, pulling a vac once should be sufficient until you need to remove nitrogen. Definitely not the entire time

Exactly.

What is is the cfm of the Venturi vac Dred Pirate uses?

“Show me your Honda civic you use to commute to work and I’ll show you a McLaren that will get you there more fastly-er. Nevermind the fact your average civic driver could never afford or have a practical use for a supercar.

That’s how you sound right now.
Edit to stay on topic: our recovery SOP for our large hydrocarbon system was also 90% passive and we only used our recovery pumps to recover the last couple gallons of butane. We actually ended up being limited by the evaporation capabilities of our system. When the recovery vessel was full with lots of surface area wetted with butane, passive recovery would absolutely RIP. As the butane level went down in the vessel, there was less wetted surface area and recovery would slow to a crawl. Honestly, pulling vacuum with the pumps never did overcome this limitation and even with it down to -10 psig, we never saw recovery faster than when it was pressurized. Heat of vaporization is real and you can talk pumps all day long, but if you don’t have your heat transfer on point, it’s not going to matter much.

are you trying to prove my point by arguing against it?
