AND it said it was a reactor of sorts. You could be the first on your block with a fully functional nuclear device. Let's see that jerky neighbor complain about my dog again. BOOM!

Keith,

That was what I was using...before I fell in. Took three weeks to get the resin off and I never did find my wallet, keys, ring, left shoe and glass eye. Decided to put it on EBay...

D
 
You know, guys, I'm thinkin' we could be working on a Guinness record here for the world's largest pen.

Think about it: We could cast and turn a freakin' Volkswagen or something....

heh

Cheers!

The term 'Reactor' does not necessarily denote nuclear.

This one appears to be a chemical reactor. Basically a vessel where you can control the pressure, atmosphere, agitation and temperature of the material you are reacting (btw...did I mention I'm a chemist? I've run many a reaction in 1 liter, glass jacketed reactors. I've even run a few in vessels larger than the one in the auction.)

BTW..chemical reactors have been known to explode when the reaction runs away. I've seen one launch the two ton top dome portion (which HAD been welded on) over 600 feet in the air. You should have seen the expression on everyone's faces.
 
Yeah.. I had one of these. I threw it out because I couldn't find the part at
Harbor Freight to hook up the venturi pump.. :tongue:

The same ol' venturi system that everyone uses on their 2 gallon pots will work fine on this baby.

It'll take several months to suck a couple of inches out of it, mind you, but when you can cast 9,000,000,032 blanks at once, a little extra time shouldn't be TOO much of an inconvenience (grin)

Cheers!

The best way to pull a vacumn on that baby would be to start a big fire under it. After it got good and hot, close up all the ports and run a water hose over it. Only problem would be you might not be able to use it a second time.:biggrin: I,m not a chemist but i do work in a chemical plant.Im the guy that makes sure all those pressures and temps and flows and mixtures dont go the wrong way.:eek:(BOOM):wink:
 
It's only 800 gallons. Even a small, 100 cfm rotary screw compressor could easily get it up to 185 psi.

Mostly Long-chain monomers and polymers. When I try to explain it at parties, I mainly get blank stares...so I just say, "We make goop."

Ever heard the term, "Oil and water don't mix."? Well, I mix 'em...and they stays mixed (mostly).

I do have some experience with petroleum products (mostly asphalt and its derivatives) and some textiles.

So, you're the operator who makes sure us research chemist don't blow upt he plant. ("Well, it LOOKED good on paper.")

BTW, for those of the forum who might not have gotten what sparhawk was alluding to...same principle here.

Like he said...."Once".

And if any think that atmospheric pressure alone would not do that, think that atmosphereic pressure is 14.7psi. An 800 gallon vessel has ~36,000 square inches of surface area (based on a vessel 6' in diameter, with 6' of cylinder and domed ends). Atmospheric pressure on that would be about 265 tons. It's equalized on a open vessel, no problem. Drop the pressure just 1 psi and close it, and you have a differential of about 18 tons.

Remember, the bigger the surface area of a simple vessel, the LESS pressure it takes to damage it.

Alright...class over.
 
In the refinery industry and oil fields, that's called a pressure vessel... this one is relatively small compared to a few I've handled... I was going to show off and looked for a picture to show, but didn't find one:mad:.. we moved one to the port of Houston when I was down there that required a split trailer with specialized steering on the rear dollies, total of about 30 wheels, the vessel was 65 feet long, about 15 or 20 ft diameter and weight mega tons... we closed down streets, called the power company (fondly known as Houston Looting and Pillaging) to lift or move power lines, 2 or 3 police motorcycle escorts and about a week of planning to make sure we could make all the turns.:biggrin:

You emulsify? Do you feel the least bit guilty for getting paid to do stuff that we all used to do for fun? :D

I wondered if you were perhaps a chemical engineer who works in the petro industry: I know some of them uber geeks. Scary bunch, them.

Cheers!

Where did it land?
Click to expand...

It launched from the third floor of an open sided building (luckily, it was on the top floor..NO ROOF).

Even more luckily, it landed on a roadway that ran between that structure and the maintenance shop. Didn't miss either structure by more than three feet,

Yes, we specialize in Inverse Emulsions (Water-in-Oil Emulsion rather than Oil-In-Water Emulsions).

Talk about guilty...in one job, one of the test required the use of unlubricated condoms...we purchased them by the gross. We also 'happened' to have a Gas Chromatograph that just 'happened' to use bottled Helium for a carrier gas. Let's see...condoms..and helium..both at our disposal...on night shifts....the possibilities.

The only petroleum I worked with was the sour crude (not suitable for gas) used to make asphalt, six-oil and a few other light hydrocarbons.

Yes, we....er..THEY..tend to be somewhat geeky.
