I just did some homework. Brand new utilizing Prochiller 30.2hp m45, Huber 915W, and pairing with two Mokon 36kw heaters (and USA built, all columns and Exergy heat exchangers) I can hit over 1,000 dry lbs/ 8 hr shift efficiently with my system design while maintaining overall quality. And using all Swagelok components, you’ll be in or around $375k.
Going the Chinese route for steel (using 316L stainless) I get get it done for around $325k. The biggest budget request would be the $210k for the chilling and heating options. But, going used, it could be far less. And the system would be Certified at that cost.
It would have to be laid out in a BizzyBee format (talking about how he does the multi-racks). And you would probably need 3 people to run it. One person on the solvent and material side. The other person on the utility and expansion side. While the other is solely packing and weighing socks. And exchanging out the waste. Recovery speeds would be well above 12lbs/min and you could throw the recovery line back into the second side of material columns to speed things up and always have a side of material columns being exchanged out. Less nitrogen in the process is being used. System can also do an awesome job at live material.
…………less labor.
