Carbon dioxide (CO2) is stored at high pressure in the steel or
aluminum tank. A CO2 tank is initially
less expensive than an air compressor and because CO2 is non-flammable,
non-explosive, and non-toxic it is easy to store and transport.
Generally, it is about the same size as a large fire extinguisher and
comes with a valve on the top and a pipe where the regulator is screwed
on. Since, CO2 does not require it allows one to work even in remote
locations or places where power is not available. The CO2 in the tank is
a liquid and stored at about 600-1000 PSI.In the present times, primarily CO2 is used to enhance the oil recovery from oil fields and to produce methane form coal-seems. In this way CO2 has an additional value reducing the total costs of CO2 segregation, also carbon dioxide is the main greenhouse gas, hence, geological storage of CO2 is indispensable. De-carbonisation of fossil fuels entails that after capture CO2 is not emitted to the atmosphere, which indicates that CO2 has to be transported to a storage site. The most technically feasible way of limiting CO2 emission is storage in tanks made of heavy steel.
Carbon dioxide tanks have emerged as one of the most promising options that exists for decreasing CO2 emissions, whilst enabling us to continue to benefit from access to widely available, low-cost fuel. However, certain precautions must be practiced when using CO2 tanks, to name a few :-
- CO2 gas tanks should be kept at a cool and dry place.
- Keep these tanks away from direct sunlight, fire, radiators, etc
- Never try to install or remove valves, etc. unless qualified to
do so.
- Take care that overtightening of the fittings of the tank can be seriously dangerous, as they may be weakend enough to break by the burst pressure of the safety valve.
