hi the physical properties side on the net is bad but the CDC (NIOSH - national institute...occupational safety and health or something like that) in the USA has some info which is usefuly for MSDS. check it out at www.cdc.gov then use the search engine eg of the info supplied NIOSH Pocket...

hi www.cdc.gov scroll down the page untill you find the search block...search for the chemical in question and voila among the first couple of results should appear a link to the hazardous material data sheet for that compound good luck

Hi Roger From my understantding a knockout drum is simply a liquid- vapour separator or flash vessel / and the only difference the pressure can makes is to shift the equilibrium so that more liquid condenses out at a given temperature, and to the construction. The liquid or liquid vapour stream...

Good day I have a limited space in which to put a condenser ( 25 x 14.5 x 2.5 cm and i required about 650 cm^2 area. At the moment I have proposed simply using bent piping (180 degree bends to form parallel tubes - looks like a snake shape) with water flowing through it. I can get the required...

Thanks Whylie I have had a look at their web sites and thats exactly what I was after. Kind regards quan1tum1 (Ryan)

Hi all My requirement is to eject liquid water from a vessel at 0.1 bar. Now this is not hard...with many pumps being sold that will accomplish this. The problem is it is very much a lab scale operation and i only have to remove about 1-2 litres an hour. I would ideally like to have a pump...

I don't know what the equilibrium position (relative humidity driving force if you like) is like in you system but is there no way that you could recycle at least some portion of your waste gas through the dryer again and increase the concentration of your solvent in the vapour phase and in this...

Hi again thanks for input...I did manage to get a fairly simplistic stefan - maxell model up and running and the column would definately have been way to big. Due to the high diffusivity of the components the concentration gradient with respect to distance is almost none existant, ie the...

I am looking for some way in which to size the vertical height required to separate water vapour and hydrogen simply by taking into account their different densities. However, the plan is to continually removed this purified hydrogen from the top of this vertical pipe which them means that...
