The solution to pollution is dilution – The mantra that was hammered into everyone in my Chem eng degree.

Pollution is seemingly not a thing if you dilute it enough, and the higher the chimney the wider the dispersion amongst the local area. The chimney will be calculated from a factor of the offgas (waste gasses) and local regs around the release of these gasses.

Hopefully this is no longer a phrase that people in the industry still use today, but it was about 7/8 years ago 🙁
