Re: teenagers poisoned in south africa

An update to this story lists the official cause of death as suffocation. Many of the families of the deceased are rejecting this as a coverup and claim the youths were poisoned in some way. I have seen firsthand accounts that claim there was extreme overcrowding, that at one point someone order man...

Re: Is it safe or not?

To be graphic, you are heating a liquid that is similar to gasoline past its ignition temperature. You're painting a picture that is far more graphic than the reality. There isn't going to be an explosion without the optimum air/fuel ratio and an ignition source, regardless of whether the still cha...

Re: Random Packing For A 4" Column

Ok a response. They do a 13 mm. MOQ is 5m3 5m3 of the 16 mm would be 1800 kg = 3960 lb. Scrap price for 304 stainless is $0.45/lb, so figure some multiple of $1782 plus shipping. To give you an idea of what that would be like, I'd expect that they would be shipped in 55 gallon drums. 5m3 would be 1...

Re: Is it safe or not?

My years of experience as a safety professional and my reading of several threads in this forum lead me to this: The primary hazard of running a high ABV through a spirit run is fire. Obviously, ethanol is flammable. Water is not. Once you cross some level of concentration, the flammability hazard b...

Unfortunately, valuable information such as column size and length are not mention in the copied.. So what was the column size that these Helices of thin wire used in.. as packing size efficiency is directly related to column size.. Figure 345, which has appeared in this forum, is for a column of 2...

Re: Structured Packing

I've now found a copy of Krell's Handbook of Laboratory Distillation (1982 edition). Figure 345, which has been reproduced in this forum several times, shows a HETP for SPP ranging from about 0.5 cm to about 3 cm. He also writes, Helices of thin wire (Grosse-Oetringhaus) have an extremely high effic...

Structured Packing

In the chemical industry, this is what they call structured packing. It's layers of metal gauze (or plate), crimped into v-shaped corrugations at an angle to vertical of 45-60 degrees. Then each layer is placed back-to-back with the previous layer, so that droplets can bounce left or right as they d...

Howdy

I'm a somewhat nerdy guy who used to get paid to help people get high. I hope to keep my usefulness/annoyance ratio here.

At this point, I'm just learning about the hobby and trying to get a handle on theory and practice.
