Styrene odour destruction

The chemical name is Phenylethene. C6H5CH:CH2 melting point -31c :Boiling point 145c. Try an extracter system and pass the air into a condencer that has the temp set to -35c.

Thanks Guest, What are you suggesting the end result would be? I assume that as we are starting as a gas, if we reduce the temperature to -35 we would end up with a liquid.

I also assume a pressure component could be involved

The method of using a Negative Ion generator was based in the industrial chemist report shown as the following. C6H5CH:CH2+10 O2 reduces to 8CO2+4H2O.

The idea is to get a solid that you can then either disolve to re-use or let it warm to a liquid and then put it into containers and find a way to dispose of it from there on.

This is just a "try this" approach, as I have not tried it. The comtaminated air, containing styrene vapor, can be pumped into (through) a solvent solution which contains an active free radical generator (peroxide) which is active at ambient, or the apparatus can be heated. Since styrene contains a C = C, this bond can be attacked by radicals to form polystyrene and ethyl benzene. Solvents such as ethanol or ethyl acetate are acceptable, but you may want to pass the cleaned air thru a filter to remove flammable, and potentially toxic, organic vapors. A simplier and less active procedure would be to simply pass the contaminated air thru an activated carbon filter. Many factories use large activated carbon filters to clean air which contains organic vapors. The activated charcoal can be regenearated, or replaced, as needed. If you use a water bath for the styrene vapors, liquid styrene will form at the water-atmosphere interface, and it can be returned to the cleaned circulating air!

Thanks Cardio07,

I believe activated carbon filters were tried, however while effective, due to the concentrations of styrene vapour they were saturated in a very short and economically unacceptable time. I had heard of the water bath method and also incineration, both very expensive to set up and still have a by-product problem.

The refrigeration/condensing method sounds interesting as its in my own line of work, again the set-up cost maybe unacceptable. Lets keep the ideas flowing and thanks.

Hey

You mention 'odour destruction', whats that got to do with chemically reacting with the volatiles, I mean to say odour is a sensation, not a chemical, and if it stinks and people in the area are complaining about the odour, why not just sweeten it up with some ester.
