What Differences are therebetweenLPG and Natural Gas?

As most of you might be aware, natural gas is present in nature as a mixture of methane and other gases, whilst LPG (liquid petroleum gas) is aby-product of both petroleum refinement and natural gas processing. Natural gas has to be cleaned before any usage, and by-products of this procedure include hydrocarbons like LPGplus butane, ethane, and pentane.

The main differences between LPG and natural gas in household usage comes down to their energy effectiveness, price, compression, storage, and elements of risk. However, when it comes down to how well they perform in all appliances for heating, cooking, or drying, there’s very little difference.

Cost vs Energy

LPG provides more energy per unit of volume than does natural gas. While LPG is normally measured in gallons (or litres), natural gas is found in cubic feet (or cubic metres). Heat is measured in British Thermal Units (BTUs), which is the amount of heat required to raise the temperature of 1 pound (0.5 kg) of water by 1°F (0.56°C). When the volume of energy each produces is examined in contrast, both are determined in their gaseous form.

Natural gas provides a little over 1,000 BTUs per cubic foot (0.0283 cubic meters); whereas the same amount of LPG gas in gaseous form affords about 2,500 BTUs. This means that LPGaccommodates about 2.5 times more usable energy content, in which case less LPG is required to make the same amount of energy as natural gas.

Performance and Choice

When it utilised for heating or cooking, the majority of people cannot tell any difference between the two gases. A number of barbecue devotees prefer natural gas due to it being a cleaner burning fuel, which means that it won’t give off as many pollutants. CNG has to be kept at much higher pressure than LPG, so the tanks are usually somewhat larger and heavier.

Matters of Storage

One characteristic in the physical properties of LPG and natural gas is how easily they can liquefy and are transported. LPG transforms into a liquid at -46°F (-43°C), but when if it's held under pressure, it will remain a liquid even when at much higher temperatures, which allows it to be stored and transported in portable steel tanks.

Matters of Risk

LPG is heavier than air, which makes it heavier than natural gas. Both LPG and natural gas will evaporate into the air if they happen to be released in an open air environment, and both also can pose an explosive risk if they are concentrated enough and ignited. Due to LPGbeing heavier than natural gas, however, it tends to fall to the ground, gather, and then pose a greater explosive risk than natural gas, which rises and dissolves into the air. CNG, which is stored at very high pressure, will be more likely to explode if the storage tanks happen toget damaged.

This is why these gases are contained in special safety tanks and kept in safe places when used.
