Figured I’d make a post on here to introduce my equipment company and our membrane skids
This is our 60 GPH 2in1 membrane skid for winterization and solvent recovery.
This skid can be used for winterization, terpene seperation, color removal or solvent seperation based on what membranes you put in them.
This setup is currently being peer reviewed by PSI for C1D1 certifications.
These skids will work with ethanol, methanol, ethanol denatured with heptane, hexane, pentane, butane, propane, isobutane, and toluene
Our skids include a heat exchanger for temperature control and a c1d1 remote controller attached on the skid for the control area
PLC and full automation add ons are an option (this is our most basic model)
We will have a 10 gph, 30 gph, 60 gph (this model), 90 gph, 200 gph and 400 gph (we can do custom sized based on customers needs) each of these skids will have up to 4 stages based on customer needs
Live in person demos start 4/19/21
Message me for details!
It’s taken forever but it was all worth it!
Rome wasn’t built in a day
It pumps! Can you do terp strip from heptane with it?
What’s the ballpark cost on one of the smaller skids?
Yes, I think hydro carbons are best for terp strip tbh
I’ve found with my clean up SOP heptane is easier to remove then ethanol from the final terpene product
The 10/15 gph will be around 40k
30 will be around 70
60 will be around 100k
We’re still getting our pricing together on the larger skids
These will all come c1d1, hydro carbon membrane upgrades will run around 2-5k depending on the model you have
The hydro carbon membranes will run any of the solvents I listed
The ethanol ones will only run alcohols
Were also working to develope a membrane CRC stage with a Lenticular carbon filter and inline CRC
That’s a really sexy-looking piece of kit.
How many amps does your 400 GPH skid need?
I assume the GPH numbers are with Ethanol.
What should I multiply those numbers by to get a rough GPH for Heptane?
The 400 single stage would take around 45-50 amps 3 phase 480, when it runs it wouldn’t use anywhere near that amperage though
The heater/chiller you use to keep the system at temp will use more electricity based on what model you choose (we can help you size the right size heater chiller for the job. You need heating for the cleaning before shutdown)
Ballpark how many kW of heat do you need for a 400 gph?
Ditto cold, and at what temp?
I’m saying fuck it and making a huge portion of our equipment custom, so I’ll just build whatever it requires and take the kW off the system loop.
There really isn’t much heat generated besides the friction that the high pressure valve creates, id guess 2 or 3 kw would be more then enough to keep your system at temp ill get you some better #s on that soon im working on calculating the heat increase based off the flow and pressure
The heating you shouldn’t need more then 5 - 10kw
Our cleaning and shut down sop has you push clean solvent through the system (room temp) to get any remaining crude out, you close off the membranes then use the heat exchanger bypass with the heater to heat up fresh solvent (you recirculate till you’re to desired temp) to the max temp of the membranes then push that across the membrane to clean them then shut down
Heating requirement really comes down to how long you want to wait to heat up fresh solvent
Our PLC skids will do this automatically and we’re even working on heater chiller control integration with certain heater chiller combos (like julabo and polyscience)
From my trials on heptane it runs around the same speed as ethanol
Heres room temp winterization in heptane with the hydro carbon membrane
Sounds like built in CIP. I like it. That’s a feature that makes life a lot easier.
We offer a 1 year warranty on all our systems
Part of the requirement of the warranty is for you to keep maintenance logs so if you have a problem and we have to come it we have logs to look at
(99% of the time ppl have problems because they don’t keep a proper cleaning schedule)
The PLC system keeps logs of this automatically which makes life 10x easier for you
Do you have data sheets from the manufacturer of those pump heads saying they’re cool for pumping liquid alkanes?
These pumps are used in the oil&gas industry and are approved for hydro carbon use
The pump is constructed of a SS 304 body with ceramic pistons and ptfe seals, it cannot spark
PSI is reviewing our skid and has no problem with these pumps as they’re designed to be used in gas industry in C1D1 environments
If you’d like to read more about the pumps we use from the manufacturer youre more then welcome to see some of the applications they’re used in at the link above
Whats really cool about Cat is you can call them and tell them your exact application and pressures and they will quote you the exact pump you need
They’re a legit company who stocks 99% of there stuff so if we ever need anything we can get it next day aired from the mid west (obviously you’re in Canada so transit times will be different)
We’re planning on stocking replacement membranes too so we can next day air membranes to ppl who need them
It does not appear that you have the class I div I electrical interface
with motor attached yet. There seems to be about an extra 10K
in explosion proof goodies, the appropriate gas detector 1.5K and another 15K Factory Mutual stamp missing? Controller will need
a NEMA 4x SSbox…like half the job is missing. I’m just pointing this out for your liability which you seem to be aware of. Final end product may be a bit more expensive,
I’d like to see a demo? Location?
Note: (in his latest post-edits KofK addresses all these issues including certification: “reviewed by PSI for C1D1 certifications.” )
Everything we need is there, not sure what you’re talking about
The VFD is mounted outside the control room and you run conduit to the c1d1 Larson controller
We need to finish the wiring, there’s no more c1d1 components required though
This demo unit will be installed outside under an awning which is why we’re not too worried about full c1d1 on this one
Demos will be in Grass Valley, CA or over the internet
I got a shitty rep who didn’t like the demon lettuce and told me “no quote” when I asked for an C1D2 pump for heptane or ethanol. Should have tried a different rep
This is how we’re building our entire system. One big set of PLC cabinets on the other side of the wall from the extraction room.
You’d be surprised how expensive c1d1 VFDs are lol
This is how were going to do it too on the big systems with PLC
These smaller systems have a Larson controller that controls the VFD with speed control and an on and off
There’s a way around that though. Inerting is your friend.
