#BiochemAcademy #CNG,#LNG, #LPGTopic CNG , LNG , LPG The main and basic difference between CNG,LNG,LPG these three types of fossil fuel .This video covers t Natural gas (NG), liquified petroleum gas (LPG), and liquified natural gas (LNG) are made up of the same elements in different quantities. As a result, they differ in density, energy content, storage needs, combustion requirements, and delivery methods. Natural gas is piped into residential, commercial, and industrial properties, whilst LPG is Liquefied fossil gas is formed when fossil gas is supercooled into its liquid state at about -260 degrees Fahrenheit (-160°C), a process known as liquefaction. It is then loaded onto huge tanker ships or trucks and exported abroad, where it is returned to its gaseous state in the process of regasification. It can then be transported as fossil 1 gallon of heating oil (with sulfur content at 15 to 500 parts per million) = 138,500 Btu. 1 barrel of residual fuel oil = 6,287,000 Btu. 1 cubic foot of natural gas = 1,036 Btu. 1 gallon of propane = 91,452 Btu. 1 short ton (2,000 pounds) of coal (consumed by the electric power sector) = 18,820,000 Btu. LNG vs LPG Fuel Costs. Another major difference of LNG vs LPG is cost of fuel and price volatility. Historically speaking the price of propane is very volatile. In last 5 years prices have ranged from over $4.00 per gallon to as low as $.75 per gallon. A reason for the volatility is propane price is derived from price of crude oil, weather and This study provides a direct comparison of the explosion severity between commercial propane and natural gas. Empirical correlations available for vented vessel explosions and unconfined Vapor Cloud Explosions (VCEs) are used to predict the difference in overpressure expected for a commercial propane explosion versus natural gas explosion. ClLxaEQ. The main difference between CNG LNG and LPG is that CNG is mainly composed of methane gas and contains small amounts of other hydrocarbons, and LNG is a natural gas that has been cooled to a very low temperature of approximately -162 degrees Celsius, whereas LPG is a mixture of hydrocarbon gases, mainly propane and butane. Reference: 1. The reason for this difference is because LPG contains much more energy than natural gas. A cubic foot of natural gas contains something like 1,000 BTU (British thermal units) of energy. A cubic foot of propane contains perhaps 2,500 BTU. You can see that if you take a gas appliance set up for natural gas and then run it on LPG, the appliance This can be accomplished with a strong metal tank. To keep natural gas a liquid, it requires a room temperature and maintains a pressure of about 32,000 kPa. Household metal tanks cannot resist this pressure. Natural gas is not stored in household tanks because the symmetry of its molecule makes it hard to liquify. Infra support needed. Applications: Buses, Trucks. >90% is Methane and 3-4% is Ethane. CNG is also very light, so if there is a leak, it will dissipate rapidly into air but LPG will settle on ground. This makes CNG a safer choice over LNG. CNG releases less GHGs. Hydrogen Enriched Compressed Natural Gas (H-CNG) It has been found by many people who opted for gas on the pipeline that it is actually turning out to be cheaper than an LPG cylinder. The latter costs close to Rs 290 in Mumbai and estimates put the gas bills to be 30% cheaper than an LPG. But then, this is just the running cost or the monthly bill. While zeroing on any service, there are also
