Chemicals, Pharmaceuticals and Petroleum Industry Uses:
Large quantities are used as a raw material in the chemical process industry, especially for methanol and urea production.
Carbon dioxide is used in oil wells for oil extraction and maintain pressure within a formation.. When CO2 is pumped into an oil well, it is partially dissolved into the oil, rendering it less viscous, allowing the oil to be extracted more easily from the bedrock. Considerably more oil can be extracted from through this process.
