I am very unfamiliar with molecular sieves so forgive me if this is a ignorant question.
Why aren’t membranes industry standard for first step solvent recovery? Or is this just a well kept secrete? [Edit: it is standard for non CO2]

Membranes are emerging onto the market more and more everyday
I can winterize and remediate color with a membrane
My solvent recovery skids will hit the market pretty soon
Just you wait friends! Many interesting things in this field coming this year

Maybe starting with Revursed osmosis which is a couple of years old.
Evonik?
No, they’re too expensive
How about a triple fraction? One membrane for the stuff larger than CBD and a second to remove solvent.
I did the math about 4 years ago and if I remember correctly 0.3 µm pore was big plenty big enough for CBD to pass though, now I am wondering if it can be even smaller. Can anyone confirm this?
[Edit: never mind I found the answer in an old post, looks like 0.2 um is standard]
