What is calorific value of LNG?

What is calorific value of LNG?

A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.

What is the calorific value of LPG?

around 46 MJ/kg
When liquefied under pressure, the volume of butane and propane is reduced to around 1/260 of the gaseous aggregate state. The specific calorific value of LPG is around 46 MJ/kg or 12.78 kWh/kg depending on the composition of LPG.

What is the calorific value of CNG and LPG?

LPG has high calorific value of 90 to 95 MJ/m3 compared to CNG which has calorific value of as low as 35 to 40 MJ/m3. Thus, LPG is more efficient fuel than biogas, petrol, diesel, kerosene and CNG.

How do you calculate net calorific value of natural gas?

Net Calorific Value (NCV) or lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of vaporization of the water vapour from the higher heating value. It assumes water vapour leaves with the combustion products without fully being condensed. Fuel should be purchased based on NCV.

How is gas liquefied?

Liquefaction of gases is the process by which substances in their gaseous state are converted to the liquid state. When pressure on a gas is increased, its molecules closer together, and its temperature is reduced, which removes enough energy to make it change from the gaseous to the liquid state.

Which has higher calorific value LPG or natural gas?

It is the amount of energy in food or fuel, determined by measuring the heat generated after complete combustion of a fuel or food unit mass. For example, the specific calorific value of LPG gas is around 46 MJ/kg. Notably, LPG has a higher calorific value than natural gas.

How do you calculate calorific value?

Goutel suggested the following formula from calculating the higher calorific value when the percentage proximate analysis of fuel is known. The formula is, cal. value = 343.3 x fixed carbon \% + α x \% volatile matter kJ/kg.
