466 Questions
Why lpg is better fuel than coal?
LPG is considered a better fuel than coal because it is cleaner burning, causing fewer emissions of pollutants such as sulfur dioxide and particulate matter. LPG is also easier to handle and transport than coal, as it is a gaseous fuel that can be easily stored in tanks. Additionally, LPG combustion releases fewer greenhouse gas emissions compared to coal, making it more environmentally friendly.
Does the gas in cylinders ie LPG if leaked from cylinders has any harmful affect?
Yes, leaking LPG can be harmful as it is a flammable gas that can catch fire easily, leading to potential explosions. Inhaling LPG can also cause symptoms such as dizziness, nausea, and headaches. It is important to address any LPG leaks immediately and ensure proper ventilation in case of exposure.
What is the calorific value of LPG in kcal?
The calorific value of LPG (liquefied petroleum gas) is approximately 46,000 kilocalories per kilogram.
Is 1 kilogram of liquid LPG equal to 1 kilogram of LPG vapor?
No, 1 kilogram of liquid LPG will have a higher energy content than 1 kilogram of LPG vapor because the liquid form is denser and contains more molecules packed closely together. This means that the liquid form will provide more energy when burned compared to the vapor form.
Is burning of LPG an exothermic or endothermic reaction?
It releases heat, therefore it is an exothermic reaction.
What strong smelling substance is added to lpg?
A strong-smelling substance called ethanethiol is added to LPG (liquefied petroleum gas) to give it a distinctive odor. This odorant is added as a safety measure to help detect gas leaks and alert individuals to potential dangers.
Difference between butane gas and LPG?
Butane gas is a specific type of liquefied petroleum gas (LPG) that consists mainly of butane, whereas LPG is a broader term that includes propane, butane, and other hydrocarbons. Butane gas typically has a higher boiling point and is used in portable stoves and lighters, while LPG is commonly used for heating and cooking in homes and businesses.
LPG stands for Liquid Propane Gas. The composition may vary, but the major component is Propane. There will be a mixture of other hydrocarbons in the gas but Propylene is likely to be the next most abundant.
What is the difference between LNG LPG and CNG?
Compressed Natural Gas or CNG is stored on the vehicle in high-pressure tanks - 20 to 25 MPa (200 to 250 bar, or 3,000 to 3,600 psi). Natural gas consists mostly of methane and is drawn from gas wells or in conjunction with crude oil production. As delivered through the pipeline system, it also contains hydrocarbons such as ethane and propane as well as other gases such as nitrogen, helium, carbon dioxide, sulphur compounds, and water vapour. A sulphur-based odourant is normally added to CNG to facilitate leak detection. Natural gas is lighter than air and thus will normally dissipate in the case of a leak, giving it a significant safety advantage over gasoline or LPG.
Liquefied Natural Gas or LNG is natural gas stored as a super-cooled (cryogenic) liquid. The temperature required to condense natural gas depends on its precise composition, but it is typically between -120 and -170°C (-184 and -274°F). The advantage of LNG is that it offers an energy density comparable to petrol and diesel fuels, extending range and reducing refuelling frequency.
The disadvantage, however, is the high cost of cryogenic storage on vehicles and the major infrastructure requirement of LNG dispensing stations, production plants and transportation facilities. LNG has begun to find its place in heavy-duty applications in places like the US, Japan, the UK and some countries in Europe. For many developing nations, this is currently not a practical option.
Liquefied Petroleum Gas or LPG (also called Autogas) consists mainly of propane, propylene, butane, and butylene in various mixtures. It is produced as a by-product of natural gas processing and petroleum refining. The components of LPG are gases at normal temperatures and pressures. One challenge with LPG is that it can vary widely in composition, leading to variable engine performance and cold starting performance. At normal temperatures and pressures, LPG will evaporate. Because of this, LPG is stored in pressurised steel bottles. Unlike natural gas, LPG is heavier than air, and thus will flow along floors and tend to settle in low spots, such as basements. Such accumulations can cause explosion hazards, and are the reason that LPG fuelled vehicles are prohibited from indoor parkades in many jurisdictions.
Main difference between auto lpg and lpg is 1,3 butadiene %.<0.5%Max is recommended, where as >0.5% for Bulk lpg.Crack run LPG contains more Octane number ,where as Straight run LPG contains less Octane number.
Yes, quite easily if the right conditions are met. All it takes is someone to light a match or turn on a light switch. Additives are put in the LPG so leaks can be detected by smell or sight (it is otherwise an invisible, tasteless and smell-less gas).
Pentane is typically present in small concentrations in LPG, which is primarily composed of propane and butane. The exact amount of pentane in LPG can vary depending on the source and production methods, but it is generally found in trace amounts.
Which compound is added to LPG to detect its leakage?
A compound called mercaptan is added to LPG to detect its leakage. Mercaptan is a sulfur-containing compound that gives LPG a distinctive smell, making it easier to detect any leaks as it has a strong odor.
What is the Calorific value LPG in kWh?
The calorific value of LPG (liquefied petroleum gas) is usually around 46.1 MJ/kg, which is equivalent to approximately 12.8 kWh/kg. This value may vary slightly depending on the specific composition of the LPG being used.
Why should we use LPG instead of coal?
Using LPG (liquefied petroleum gas) instead of coal has environmental benefits as it produces less greenhouse gas emissions, sulfur dioxide, and particulate matter. LPG is also a cleaner fuel, emits fewer pollutants, and has higher energy efficiency compared to coal. Additionally, LPG combustion is more versatile and can be used in a wide range of applications such as cooking, heating, and transport.
How Many Litres of LPG equals 1 Cubic Meter?
Conversion factor depends on various factors like composition of the LPG, temperature, molecular weight and so many others.
Following are the conversion factors just for rough calculations.
One kg of liquid Propane when converted to vapour (at 15.56 degrees centigrade temperature) will be equal to 0.539 Cubic Meter.
One kg of liquid Butane when converted to vapour (at 15.5 degrees centigrade temperature) will be equal to 0.410 Cubic Meter.
One kg of liquid LPG (70:30) when converted to vapour (at 15.5 degrees centigrade temperature) will be equal to 0.449 Cubic Meter.
OR
45kg LPG = 20.20 Cu. Meter vapour. Or for 45kg Propane = 24.26 Cu. Meter of vapour.
As a thumb rule Liquid Propane expands to 270 times and Butane to 235 times into vapour when released into air.
How many liters of LPG makes a one ton of LPG?
A one tonne of Lpg makes up on the density of the product is around 1,785 litres
Yes, LPG (liquefied petroleum gas) is a mixture of propane and butane gases. These gases are compressed into a liquid form for easier storage and transportation, and are commonly used as fuel for heating, cooking, and vehicles.
What is the composition of LPG?
LPG (liquefied petroleum gas) is a mixture of propane, butane, and other hydrocarbons. The composition can vary depending on the source and processing methods, but propane and butane typically make up the majority of LPG.
How do you convert pound LPG to gallons?
To convert pounds of LPG to gallons, you need to know the specific gravity of the LPG. Once you have the specific gravity, divide the number of pounds by the specific gravity to get the equivalent volume in gallons.
How many nm3 of lpg makes 1 kg of lpg?
1 kilogram of LPG is equivalent to approximately 1.96 normal cubic meters (Nm³) of LPG.
What is the composition of lpg gas?
The normal components of LPG are propane (C3H8) and butane (C4H10). Small concentrations of other hydrocarbons may also be present.

The specific gravity of LPG (liquefied petroleum gas) is typically around 0.50 to 0.58 at 15.6 degrees Celsius (60 degrees Fahrenheit). This means that LPG is lighter than air and will tend to rise if released in an open environment. It is important to handle LPG with care due to its flammable nature.
Change-a (LPG changing from liquid to gas) is a physical change. It does not involve any chemical reactions, as the molecules of LPG remain the same as it transitions between its liquid and gas states.
Chemical constitution of the LPG?
LPG stands for liquefied petroleum gas, which is predominantly made up of propane and butane. These gases are hydrocarbons that are easily liquefied under moderate pressure, making them suitable for use as a portable fuel source. Additionally, LPG may contain small amounts of other gases like ethane, propylene, and butylene.
