Failures

Did a nitro assist from a cold solvent tank, only because of another failure which was forgot to tighten the line on the tank did I notice oil in my solvent right off the tank nipple…:man_facepalming: my tank was colder so basically it was recovering back into itself because the crc takes a bit to get cold and flow through

My dad used to tell me; “if you aint making mistakes, you aint workin or learnin” and “the best thing you can do with a mistake is learn from it” – (Ive made a few…)

*Modifying a heat transfer loop, with an old school hot oil heater (with no internal by-pass) Didnt use lock/out -tag/out back then. Welders finished and we started the heater up. Evaporator temp wasnt rising as we expected. We discovered the closed valve before we got sprayed with hot oil, but the heater was “dead”. – (likely salvageable)

*Trying to adjust/reset/reseal a 4" ANSI flange while system under vac during vac test. Someone put too much seal grease put on gasket, Gasket sucked into condenser column. – (big pain in the ass to retrieve)

*Trusted a seasoned technician who was “sure” they installed a valve and “verified” its positioning by signing off on commissioning checklist. Turn system on, initiated feed, and instead of sending tincture to evap tower, 50L+ of solvent/oil shot into high into the air out of an open port on downstream reactor. Now we have double redundant checklists/signoffs. – (thank god for proper PPE, ventilation and all EXP components)

*On a liquid ring vacuum pump (mock up test), got lazy and used zip ties for a temporary discharge hose, upon startup, zip tie didnt hold long and shot a column of water on the 30ft tall ceiling. – (the drips from ceiling on my head even after 5 minutes really made me feel super stupid)

When I first started running nitrogen assist I didn’t sufficiently tighten my splatter platter hp clamp and blew a couple pounds of solvent laden oil into the cooler the collection vessel was in and made a dry ice/tane/oil slushy. Made for an interesting day.

man i would have cried :woozy_face:

Had a company install a manifold for our dewaxer, so that we could turn the cold jacket fluid on it or not, while the valves were closed the liquid inside the jacket went from a super condensed state at -70C and expanded to its normal state at room temp with no where to go cause the manifold they installed blocked it, the expansion imploded the jacketed stainless steels walls like they were playdoh completely took out a 6"x36" material column and put a fat dent in a 3" dewaxing column.

Companies tech installed a chiller and closed loop system and didnt set up the overflow system on the glycol chiller, and kept it plugged, then overfilled it and shot glycol all over the internal components. They bought us a new chiller since it got toasted by getting every component effectively drenched in glycol

My boss at last job broke a beaker with a liter of distillate inside by putting it in a hot plate immediately after removing it from our refrigerator, there was basically none left that was salvageable, same guy dropped 2 liters of winterized crude on the floor/himself after removing from the 150C hotplate it had been on for 3+ hours decarbing, it melted his shoes if he wouldnt of had steel toes it would of been much worse still burned a huge chunk of skin off his foot.

Assume all vessels have pressure. Started tagging any units that are under any kind of pressure.

We had a 12L flask ruined by exhaust that was posing as crude from an outside source. Should have had the stuff tested before running.

Couldn’t figure out why my system wasn’t recovering. Found out that there was moisture in the coil and ended up freezing when I put it in dry ice. Make sure recovery path is clear.

Just wow!

Thank you all for sharing.

I’m not 100% certain that “liking” any of those posts feels appropriate to me :thinking:

I certainly like the spirit in which they are offered.

Learning from our own mistakes is one thing, others letting us learn from theirs is rare.

Bravo :clinking_glasses:

Fatal error: freezing material, letting it thaw or melt in any way, then cooling it again

Ice crystals cover the trichomes, effectively drilling your yields in the ass with a fat dildo

Lmfao!

I had my vac line get full of etoh during just this.

Blast off! My thermometer and adapter hot my ceiling and then the glass cracked on the tile floor. It still holds vac (lol). Been waiting 4 weeks for replacements to get in stock at my local glass-r-us (usalab) store.

Seperate fail
Edit
And my vac pump (trivac, spare now), STILL reaks like burnt ammonia from my last run I did for the asshat, I mean lying client. I’ve flushed 2x and did 3 oil changes. Still no bueno.

Not my mistake but I have pics. Do not do this to your pumps. There was a wax trap and mol sieve filter.

I’ve seen that grease on brand new trs’s Before. Cps don’t give a fuck about us or our health and take all the shortcuts they can making that pump. Included are using hot glue to help make it “sparkproof” or whatever, and that nasty black I’m sure non food grade grease on the pumps internals… I bet that crap was in your buddy’s pump from jump.

Nope, that right there is errr was crude. A lot of it. I had more pics that didn’t post. And I know what it looked like before, not her first time on my bench.

A minor issue comparatively, but always keep a second trusted thermometer of one sort or another around.

In the beginning I wasted many hours waiting for CBD to dissolve in a luke warm solution because I mistakenly believed the digital readout on my equipment and apparently have girly fingertips now… I miss my cook hands.

Opening a pressured collection vessel on a 5 lb butane C LS. Entire upper body covered in BHO as well as my car, funny thing was the car was such a piece of shit, i estimated the BHO on the car was worth 4x as much the car. Still drove it around Seattle collecting dust and hair :slight_smile:
