Environmental Laws requires that smoke stack emission be limited. I have a smoke stack scrubber design that is economical and easy to construct. First, you cap the top of the smoke stack and then run a 2 foot wide diameter pipe out of the top of the smoke stack and run the pipe right back down into the burn process that produces the smoke, if it exists. At the top of the smoke stack you run a 2 inch pipe into a pan of water that has a foam rubber filter which is soaked with the water. Addititionally, if the industrial process producing the smoke or soot is not a burn process, then you build a closed burner which uses natural gas and pipe the smoke or soot into that burner. The burner could be used to supply heat or to run a steam turbine engine which could then generate electricity with an AC electrical generator turbine. The exhaust from the natural gas burn is then recycled into the burn chamber. Also, it may be possible to use the smoke or soot or chemicals in the natural gas fuel of an engine which can again drive a AC electrical generator turbine. Once again there can be a very small bleeder exhaust which can be filtered as described above.
