3" CCVM

Post by ecir54 »

Early on during the pandemic put this together. Was planning on using spp but the war messed up the source i used before so put it aside. Wasn't crazy about the stainless tee and long radius elbow so watched ebay to find a copper tee as street elbow at reasonable prices and in the mean time contemplated which media to use. Came across bushman's thread on making copper packing and i had a bunch of welding lead so said why not give it a go and decided it was time to move this project further.

Just a heads-up. If you have not installed the sight glass yet place it lower than the take-off. All you will see there is reflux dripping. Top of the packing is what you want to see.

He has a sight glass just below the takeoff. Not sure what you are trying to say. He also has one at the base of the column. I'd say he's golden when it comes to sight glasses.

You would benefit with a taller column.

Second picture? The changes he is talking about?

Okay, I did miss the first pic.

Still if you do a sight glass like the old school ones that is fixed to the column, place it lower.

still dragon sight glass is to see position of reflux coil, inline sight glass is to see top of packing

will need more 3" cu to play with height later.

Maybe today with moduler setups, it was not always like that.

There was a time when all sight glasses were fixed to the column as windows. And there was a time that sight glasses were DIY before StillDragon glasses.

But I am being pedantic

I agree that your column is going to need more length.

Will the new offtake configuration involve triclamps? I like having the ability to change the angle of my product condenser on my CCVM

yes have tri clover ferrules but more so to keep all parts modular pooling would be a problem with a shotgun at a angle.

My initial gut feeling is that a shotgun condenser at an angle shouldn’t be an issue. It is all vapor going into the condenser so it should be evenly spread across the inlet even if it is at an angle. There might be a difference in the water flow through the shotgun, but I don’t think it would be an issue. My LM still head has its reflux condenser at a 45 degree angle and I never saw an issue when running it.

well it all depends how close the vapor tubes are to the wall of the condenser will determine if there is a chance of smearing. any design that allows smearing would be a negative in my book it's why using a parrot isn't recommended to be used throughout a run.

Try holding your shotgun at a 45 degree angle and pour a bunch of water through it. Now pour out any water that 'pools' inside it and you'll see that it's only a ml or so. Even if anything did pool, it would be insignificant. A parrot is a totally different story because of the volume it holds. During a stripping run, parrots are fine. It's spirit runs where it could smear.

The input side of a product condenser is the “hot side” I doubt if there’s any condensate there during a run. There would be condensate there once the vapour column has collapsed say when power to the boiler is shut off. That condensate would be low purity if it was at the end of the run. I think people are aware of the condensate and believe it is there during the whole run.

anybody know how long of a piece of 3/8 refrigeration soft copper would be needed to do a double wound reflux coil around 10" in height?

^^^ diameter x pie x number of rows should get me close.

Had time this weekend to fit the ferrules. the street elbow was pretty thick so had to take quite a bit of material to get a hand tight snug fit.

the 3" the stainless ferules fit loose in DMV pipe and are too big for type m pipe. used type m for the sleeves in the tee and again took material off for a hand tight snug fit. this should make it easier to square the ends before soldering which would have been a pain to deal with with a loose fitting ferrules.

type m 2.981 id

Looks good. You will be happy with that. I like the flush fit of the ferrules. I did mine the same. I like it!

Have fun and stay safe.

thanks, just finished fitting this 2" ferule for the sight glass. nice and snug that needs a tap with a rubber mall to go into place. just need to trim the back side of the ferrule.

finished the rough cut on the 2" ferule next will be the fun part of trying to do a double coil 3/8 refrigeration tubing rc.

Plenty of good stuff on winding coils on here. I tried to use 3/8" tubing. But I ended up using 1/4". Let us know how you get along with your coil. Spring benders are a great help.to make that first and last bend. I found 1/4" a lot easier to wind than 3/8". Good luck.

Have fun and stay safe.

Hey wildcats have done coils in the past with good results all double row. one for 1 1/2" and 3" with 1/4 refrig tubing and one for 4" with 3/8 tubing. Was never happy with the flow restriction on the 3" with 1/4 tubing being using a pond pump for flow so am going to attempt a 3" with 3/8 tubing. The outer coil shouldn't be a problem, going to be tricky to do the inner coil with 3/8 tubing.

It's all about the mandrel size. This topic comes to mind where Hebden wound his first coil (3/8" if I recall) for his 3" VM. Filling the tubing with salt is extremely helpful in my experience.

Another helpful item for making 3/8 coils if you are worried about kink issues would be to use 3/8” elbows. They can help join two single coils and/or help anywhere you have a tight bend.

I made 3/8” copper double coil, independent I/O, dephleg/RC for a 4” column. Those little elbows made the fabrication process way easier than trying to bend everything and with no kinks, the flow rate was way larger than I would ever need. If you want to see pics of how i used the elbows, just ask and I’ll add a link here.

FYI - with 10” of coil height to work with, a single coil of 3/8 tubing is enough to easily handle 5500W.

^^^ yes that the plan also going to use a 1/2 pipe down the center to feed water to both coils from the bottom.

wouldn't have thought single 10" 3/8 would be enough to knock down 5500 watts, thanks for the info.
