give geographical reason for each of the following? CNG is used as an alternative petrol and diesel
Answers
CNG has many advantages so... lemme brief.. it is an eco-friendly alternative to gasoline. Made by compressing natural gas (methane) down to less than 1% of its volume, CNG fuel is safer than gasoline and diesel because it is non-toxic and does not contaminate ground water. This natural gas is the same gas that you use daily to heat your home and water, cook on the stove and even to dry your clothes in a dryer. The use of CNG fuel is becoming more popular with both commercial and non-commercial vehicles... more feasible, right??
Answer:
Compressed natural gas is a fuel that can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG). CNG combustion produces fewer undesirable gases than the aforementioned fuels. In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released. Biomethane — refined biogas from anaerobic digestion or landfills — can be used.
CNG is made by compressing natural gas, which is mainly composed of methane (CH4), to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 MPa (2,900–3,600 psi), usually in cylindrical or spherical shapes.
