What Is Gcv Of Natural Gas?


The quantity of heat or energy contained in a particular volume of gas is referred to as the calorific value. The transporter calculates an average calorific value monthly, which accounts for any periodic or regional fluctuations in natural gas quality.

The amount of heat released by the complete combustion of a unit of natural gas is known as the Gross Calorific Value (GCV). Higher Heating Value is another name for it (HCV).

The heat of vaporization of water vapour is subtracted from the higher heating value to get the Net Calorific Value (NCV), also known as lower heating value (LHV) or lower calorific value (LCV). This is used to treat any H

What exactly is the GCV formula?

GCV = 76.561.3(VM + ash) + 0.0073(VM + ash) GCV = 76.561.3(VM + ash) GCV = 76.561.3(VM + ash) GCV =

2 VM and ash were calculated in weight percentages on a dry basis in the preceding equation, and GCV was calculated in mJ/kg on a dry basis as well.

What is natural gas’s gross CV?

Calorific value (CV) is a measurement of heating power that is affected by the gas composition. When a known volume of gas is totally combusted under specific conditions, the CV refers to the amount of energy released. The CV of gas is commonly expressed in megajoules per cubic metre (MJ/m3), which is dry, gross, and measured at standard circumstances of temperature (15oC) and pressure (1013.25 millibars). The CV of gas travelling via our pipeline system ranges from 37.5 to 43.0 MJ/m3.

How do I find out what my GCV is?

Formula for calculating the GCV of a fuel:

  • 8137.5Kcal/kg of carbon from C+ O2 – CO2.
  • 28905 Kcal/Kg hydrogen H2 +.5O2-H20
  • Sulphur (S +O2SO2+) has a calorific value of 2181 Kcal/kg.

How can you figure out a gas’s calorific value?

Calorie value = 343.3 x fixed carbon percent +x percent volatile matter kJ/kg is the formula. For fuels with a high percentage of oxygen, the Goutel formula is unreliable.

Why does GCV have a higher value than NCV?

Because NCV (net calorific value) is the amount of heat produced by burning when the water created by combustion is still gaseous, this is the case. GCV is clearly greater than NCV since water releases heat when it condenses.

LPG vs Natural GasSummary of Key Differences

Because LPG has a higher calorific value (energy content), it takes less gas to generate the same amount of heat. The oxygen-to-gas ratio required for successful combustion is the second significant difference. The oxygen to gas ratio for LPG should be around 25 to 1. A 10 to 1 ratio is required for natural gas.

  • Unlike natural gas, which is made up of methane, LPG is made up of propane and butane.
  • Natural gas vs. LPG are two separate compounds with two different formulae: Propane is C3H8 and Butane is C4H10, but natural gas is CH4.
  • LPG is heavier than air, although natural gas is lighter.
  • LPG has a larger energy content than natural gas, with 93.2MJ/m3 versus 38.7MJ/m3 for natural gas.
  • LPG combustion requires a greater air to gas ratio of 25 to 1 compared to 10 to 1 for natural gas.
  • Unlike natural gas, which is cryogenically converted to liquefied natural gasLNG, LPG is liquefied through pressurization.
  • Unlike natural gas, which is delivered by pipeline, LPG is dispersed in gas bottles and tanks.
  • Natural gas appliances work at 1.1 kPa, while LPG appliances operate at 2.75 kPa.

LPG is superior to natural gas because it has a larger energy content, is portable and readily available, and is presently less priced in many circumstances.

Natural gas is superior to LPG in terms of pipe delivery and the fact that it emits somewhat less CO2 when consumed.

When comparing LPG with natural gas, propane is heavier than air and will settle, whereas natural gas is lighter than air and can dissipate more quickly if a leak occurs, perhaps providing a safety advantage over LPG.

In summary, there are differences in energy content, density, storage, transportation systems, and the amount of air necessary for optimal burning between LPG and natural gas.

Even though both are combustible hydrocarbon gases, LPG (LP) gas is not the same as natural gas. They are, nevertheless, employed for a lot of the same things.

Natural gas and LPG are widely available and are utilized in thousands of applications in homes and businesses.


LNG (Liquefied Natural Gas) is cryogenically liquefied natural gas (methane). LPG Propane and butane alone or in mixes liquefied under pressure make up liquefied petroleum gas. LPG is made from the refining of crude oil and the processing of natural gas. CNG Natural gas compressed at a high pressure is known as compressed natural gas.

Because natural gas (methane) is lighter than air, it will usually spread if a leak occurs. From a safety standpoint, this is preferable to LPG. When it comes to LPG vs LNG, low pressure is employed to liquefy LPG against LNG that has been cryogenically liquefied. At room temperature and pressure, both are gases (NTP).

Cylinders or tanks are used to store, transport, and distribute LPG. After regasification, LNG is kept and shipped in special cryogenic tanks before being distributed via pipeline.

LNG (Liquefied Natural Gas) is natural gas (methane) that has been cryogenically liquefied at 161 degrees Celsius and stored in tanks. LPG is propane that has been liquefied and stored in cylinders under low pressure. CNG (Compressed Natural Gas) is a cylinder of highly compressed natural gas (methane). At NTP, everything is gas.

After regasification, LNG is stored and delivered in cryogenic tanks before being dispersed through pipes. Cylinders are used to store and distribute both LPG and CNG.

CNG is a cylinder of highly compressed natural gas. LPG, propane, and butane are liquefied gases with a temperature of 20C and a pressure of 1 atm (NTP). Under pressure, methane remains a gas. LNG is only cryogenically liquefied.

Is Propane Natural GasIs LPG Natural Gas

Propane is not natural gas, and LPG is not natural gas. Methane is found in natural gas, while propane or butane is found in LPG.

The most significant distinction between LPG and natural gas is that they are separate gases, with LPG being propane (C3H8) and natural gas being methane (CH4). Natural gas is not LPG-propane. Propane (LPG) is a natural gas liquid that is processed from the raw natural gas that comes out of the well. It is also known as one of the natural gas liquidsNGL. LPG-propane comes from a crude oil refinery as well.

Natural gas is primarily made up of methane, whereas propane is solely made up of propane. LPG-propane is provided in a gas bottle, cylinder, or tank, whereas natural gas is distributed by gas mains or pipelines. Natural gas bottles are heavier than CNG bottles.

Other differences include energy content, storage, density, and chemical formulas, to name a few (formulae).

LPG vs Natural GasDifference Between LPG and Natural Gas What’s the Difference Between Natural Gas and LPG

The most significant distinction between natural gas and LPG is that they are made up of different compounds. Methane (CH4) is found in natural gas, while Propane (LPG) is found in LPG (C3H8). LPG is derived through natural gas processing and petroleum refining, and it is a byproduct of both processes.

Unlike natural gas, which is stored and delivered as a gas in pipes or gas mains, LPG is kept and supplied as a liquid under pressure in gas bottles or tanks. LPG is separated from hydrocarbon mixtures by separating it from natural gas or refining crude oil vs. natural gas with only NGLs and impurities removed.

LPG is heavier than air, although natural gas is lighter. At ordinary temperature and pressure, both are gases (STP).

One of the differences between LPG and natural gas is their chemical nomenclature, with LPG being called propane and natural gas being called methane.

The chemical formulas of LPG and natural gas are also different, with Propane having the chemical formula C3H8 and Methane having the chemical formula CH4, which is the same as purified natural gas.

The following are the differences between LPG and Natural Gas, or LPG vs Natural Gas (propane vs methane).

  • Natural gas vs. LPG The chemical formulae of (propane vs. methane) are different: C3H8 is the chemical formula for LPG-Propane. CH4 is the chemical formula for natural gas methane.
  • The energy content of LPG and natural gas is another distinction. LPG has a calorific value of 93.2MJ/m3, which is higher than natural gas (heating value of natural gas), which has a calorific value of 38.7MJ/m3.
  • The air to gas ratio for LPG vs natural gas for optimum combustion is roughly 25 to 1, whereas the air to gas ratio for natural gas is 10 to 1.
  • LPG (propane) is denser (heavier) than air, with a relative density of 1.5219:1 versus 0.5537:1 for natural gas, which is neither heavier nor lighter than air.
  • Unlike compressed natural gas (CNG), which must be cryogenically converted into liquid natural gas, LPG (propane) can be compressed into a liquid and stored or transported in a cylinder or bigger vessel (LNG)
  • The pressures of LPG and natural gas appliances are different.
  • Natural gas, often known as mains gas, is provided by gas mains or pipelines, whereas bottled gas is LPG. Propane (LPG) is a bottled gas (methane and propane).
  • LPG (propane) can be simply converted into SNG (Simulated Natural Gas) and utilized as a natural gas alternative. In reverse, however, this is not the case.

Difference Between LPG vs Natural Gas Properties (Propane vs Methane)

The most obvious distinction between LPG and natural gas is in their physical qualities. When comparing the energy content of LPG to that of natural gas (93.2MJ/m3 vs. 38.7MJ/m3), LPG has a larger energy content. LPG has a higher specific gravity than natural gas, 1.5219:1 vs. 0.5537:1, among other differences mentioned below.

What is the definition of caloric value?

Calorific value is calculated using the bomb calorimeter and is defined as the number of calories produced when a unit amount of substance is totally oxidized.

What is the difference between LCV and HCV in terms of fuel?

The fundamental distinction between HCV and LCV is that byproducts of the reaction are permitted to cool to ambient temperature in HCV, whereas byproducts are allowed to escape in LCV. As a result, in HCV, some of the heat that would otherwise be lost with the byproducts can be recovered, whereas in LCV, part of the heat is taken away by the steam. Furthermore, LCV is equal to the value produced by subtracting HCV from the heat transported away by steam.

HCV (higher calorific value) and LCV (lower calorific value) are two different ways to quantify how much heat is released when a unit mass of fuel is burned. In addition, HCV stands for gross calorific value, whereas LCV stands for net calorific value.
