Why CNG is not used for cooking?
Answers
Answer:
C is for compressed, and compressed gas is still a gas. If you pour liquid NG into a tank and cork it (roughly), the pressure in the tank will set at 45 MPa, or about 4,600 psi. This is quite a tank, and must be designed very well for safety. Thick, heavy, costly to produce, and X-rayed once in a while by a specialist in a lab or in the field to see if there are cracks developing. This is just too expensive for home use. In contrast, liquid butane will only pressurize the container to 33 psi. This is a low pressure, and plastic transparent cigarette lighters hold this pressure quite well. An explosion of a cigarette lighter never killed anyone, but an explosion of a 4,600 psi gas tank would level a home, even without a flame. Propane is in between, but is still much safer than LNG. So the main reason why LNG is not normally stored in airtight tanks at home is its high pressure and ensuing safety issues. CNG is only compressed, not liquid, and you can compress it to any pressure you want below 4,600 psi (it will remain gaseous, just denser). But a phase transition to liquid helps store a lot of additional energy per unit of volume (per liter or gallon of cylinder capacity), so liquid propane is more efficient than compressed gaseous methane at the same tank pressure.
Commercial LNG tanker ships are not airtight, too. The liquid gas is constantly boiling, and the escaping gas vapor is used to power the ship’s engine; their turbines specially designed to burn natural gas. So there is no loss of gas, and no safety issues with high-pressure storage of large amount of flammable gas. But ship’s turbines operate 24 hours a day, and you have to turn off your stove once in a while, so this solution will not work for home either.
