Decarb before which step?

1. Unless extracting with CO2, most people decarb the crude extract after the solvent has been removed. So yes, after roto, before spd. Some people choose to use an oil suitable for decarb temps (120c) in their roto bath and decarb in there. A convection oven, stirring hot plate, or a jacketed reactor are also common. These 3 options also give you an easier time when devolatilizing your extract (140c ish solution temp for 5-10 min) prior to SPD.
Definitely do not decarb in the SPD.
2. When you say industrial, do you mean large scale cannabis processing? If so, we have played around with multiple different continuous flow methods for inline decarb/devol. A big tube in shell with steam is popular

1. Perhaps, but there are safety concerns when using oil in the roto bath
2. A big convection oven.
I'm not sure why CO2 needs to be ran with decarbed flower, not my specialty

On your forum, I can't post anymore today... The bot took my replies 
What safety concerns?

Sous Vide, and you decarb before you do your extraction. You'll want to read what Ringdoggie has posted on the subject. Great read, awesome info, unless you're more about wasting cannabis extract due to lower potency?

Oh that's easy, but how is that different from rotovaping ground weed in boiling water bath? Should be even better. How do I find the thread you mentioned?Sous Vide, and you decarb before you do your extraction. You'll want to read what Ringdoggie has posted on the subject.

Why? Is it because THC is lighter than THC-A by a co2?Extractions are more efficient if you decarb prior.
Is this a solubility issue?

Boiling ground weed in water? Is this even a thing? Did you want to preserve terpenes and use waaay less extract for dosing, or did you want lower quality extract like you find everywhere?
Sous Vide preserves the terpenes so they're extracted with the cannabinoids, the cannabis is NOT exposed to the water at all. Massive difference in potency.
(Search Sous Vide)https://lmgtfy.com/?q=site%3Aicmag.com+Ringdoggie
The onsite search function is not so great.(Edit: the lmgtfy lin was not meant as a slight in any way. I was getting confusion from people when I asked them to search for "site:icmag.com Ringdoggie" I'll go back to the confusing method... damn people.)

The water bath of the rotovap, which is outside of the flask, just like the water in sous vide, outside the bag.Boiling ground weed in water? Is this even a thing?

I cook meats in sous vide sometimes, its a sealed vacuum bag in a teperature controlled hot water bath, just like a rotovap, don't you think?

You've already done the extraction, so no. Sous vide is done before the extraction. Like I said, look up and read everything on Ringdoggie since we're re-hashing the existing thread information.
Have any further questions, feel free to ask here or there.

Yes, I'm well aware of what a rotovap is. **facepalm**
If they're doing scale like you suggest, they should easily have the skills to look up and use commercial equipment to do the same task the kitchen equipment does.

Read the whole thread it's only 2 pages, and you'll see the question was different, I just pointed out anything in sous vide could be done better in a rotovap, I mean in connection with cannabis. And if you have done sous vide, try it for food, it's really good, I used it for infusing butter too, a long time ago.
I'm looking for more scientific explanation for:
Why decarb at which step? There are many opinions, even in this thread and my "rotovap uses" thread.

And just to be clear: you were thinking I'm going to put weed in water and into a rotovap... sent me a presentation about how to google. I should be the one "facepalming", but no smiley by that name here, and also I'm not that kind of person.
Write the replies, smoke a joint, read again, think about it, and then post them, this is totally honest advice, I do the same, if not I usually regret it or edit multiple times.
THC is more soluble.
Is this correct? Is it better to decarb before extraction?
(I know you are an extraction maestro Troutman, I only ask for confirmation because I don't know a single thing about the subject.)
