I am doing a chemistry project but I can't find any of this on google. If you can please leave your source.
Some solutions that have already been implemented are using chemically engineered equipment to scrub the aerosol sulfur salts out of the gases from industry that escape into the atmosphere.
In order to stop acid rain formation, you must keep the sulfur out of the atmosphere. How do we do that? Remove it from the egress gas flows that are produced from processing and burning the fossil fuels that generate the harmful compounds.
I mentioned scrubbing earlier: scrubbing is employing a mechanism that effectively withdraws the sulfur compounds out of the gas stream prior to entering the atmosphere. How this occurs is simply bubbling the gas through an absorbing medium, such as amine liquids or liquid caustic. Take a piece of equipment called a vent gas scrubber: This is a caustic (sodium hydroxide) filled absorption tower that circulates lean liquid from the top to the bottom of the tower. The sulfurous gas is compressed and shoved into the bottom of the tower. As it rises through multiple contacting stages upwards, the lean caustic moves downward from the top, and essentially 'scrubs' the sulfur by absorbing out of the gas. The result is a cleaner gas leaving the top of the column, and a 'rich' caustic stream leaving the bottom that has the sulfur removed in a separate process but keeps the harmful compounds out of the air.
So: once the sulfur gets into the atmosphere, it's pretty much impossible to remove or mitigate. So: you guessed it. You have to prevent it from ever getting there.
Prevention is the key!
not really sure but you can check this site for that....
