Air Pollution Control

Low CO2 Exhaust

For cars and trucks, the filters are made to order. They are custom-built to fit each make and model. The price of course depends on the vehicle.

Vehicle filters are made to trap CO₂ from tailpipe exhaust before it's released to the atmosphere. We do this by offering a soap-like chemical of opposite polarity, potassium (K)(+). In this case, the CO₂ (-) sticks to the potassium (+) with a little help from water (H₂O).

Gasoline + air burns to create energy to move the car. Leftover waste including CO₂ goes into the air we breathe. We catch CO₂, as much as possible, before it goes out of the tailpipe. We use a filter material mixed with potassium hydroxide (KOH).

The exhaust CO₂ + H₂O meets KOH in a flow-by reaction. Immediately a molecule is formed that becomes a soluble, slightly negative, potassium bicarbonate (KHCO3) ion. The CO₂ is now captured and stays that way until the filter is removed and rinsed in a tank of water.

The CO₂ collected in the KHCO3 will dissolve in a tank of water. To safely store the captured CO₂, a small amount of additional KOH is sprinkled into the water. This action creates a chemical reaction with the dissolved CO₂ to make potassium carbonate (K2CO3), which turns the water milky white.

The tiny white particles are now solid, potassium carbonate and settle to the bottom of the tank in a thick paste. The harmful greenhouse gas, CO₂ is sequestered in carbonate.

This protective measure is a simple, inexpensive process. We can attach a scaled-up version to a slipstream on a smoke stack. A good proportion of combustion waste from a power plant can be captured and safely stored indefinitely by using a variant of this method.
