Recovering solvent pre rotovap with molecular sieve membranes?

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

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]
