Liquified Petroleum Gas (LPG)
Liquified petroleum gas (LPG) is derived from fossil fuel sources. It is composed primarily of propane and/or butane, and it burns cleanly without producing soot. It is commonly used in vehicles and household heating appliances.
466 Questions
Why lpg is a better domestic fuel than wood?
Wood is better if you have plenty of wood available and can grow more trees while you are burning the old ones. That makes you carbon-neutral, because while burning wood produces CO2, growing wood takes CO2 out of the atmosphere in equal measure.
Why does LPG gas stoves burn with a yellow flame?
A yellow flame in an LPG gas stove can be caused by incomplete combustion due to insufficient oxygen supply or improper burner adjustment. This can lead to the production of soot and carbon monoxide. It is important to ensure proper ventilation and maintenance of the stove to prevent potential health hazards.
Why will LPG sink to the floor?
LPG (liquefied petroleum gas) is heavier than air, so it will sink to the floor and accumulate in low-lying or enclosed areas. This makes it more prone to ignition and can create a flammable or explosive atmosphere. Proper ventilation is crucial to avoid a dangerous buildup of LPG gas.
How much natural gas required to produce 1 kg LPG?
It takes about 1.2 cubic meters of natural gas to produce 1 kilogram of LPG (liquefied petroleum gas). This conversion factor can vary depending on the efficiency of the production process and the composition of the natural gas.
Which property of gas helps us in detecting the leakage of lpg gas?
The property of gas that helps us detect the leakage of LPG gas is its odor. LPG gas is odorless, but a foul-smelling odorant is added to it so that any leakage can be detected by smell. This distinctive smell alerts individuals to the presence of the gas and helps prevent accidents.
Does liquid petroleum gas rise or fall indoors?
Liquid petroleum gas (LPG) is heavier than air, so it tends to sink and accumulate in low-lying or enclosed spaces indoors. This can create a potentially dangerous situation as the gas can build up and reach explosive concentrations. It's important to ensure proper ventilation to prevent this risk.
How many kilograms are there in 20 liters of lpg?
The density of LPG can vary, but on average it is around 0.54 kg/liter. So, 20 liters of LPG would weigh approximately 10.8 kilograms.
Why the LPG gas flames are blue in colour?
The blue color of LPG gas flames is due to complete combustion. When LPG burns efficiently, it produces a blue flame because all the carbon in the fuel is fully oxidized to carbon dioxide, resulting in a clean burn. If there are impurities or incomplete combustion, the flame may appear yellow or orange due to the presence of unburned carbon particles.
What is the scientific term of LPG?
The scientific term for LPG is "liquefied petroleum gas." It is a mixture of hydrocarbon gases, primarily propane and butane, which are compressed into a liquid form for storage and transportation. LPG is commonly used as a fuel for heating, cooking, and vehicles.
MOLBO stands for "Minimum Operating Liquid Base Oil" in the LPG industry. It refers to the minimum quantity of liquid base oil required for the proper operation of equipment like compressors or pumps handling LPG. It ensures that there is enough lubrication and cooling provided by the base oil to prevent equipment failure.
How much pressure a LPG cylinder can take?
Typically, an LPG cylinder can handle pressure ranging from 7 to 18 bar (100 to 260 psi), depending on the specific type and design. However, it is important to always follow manufacturer's guidelines for safe handling and use of LPG cylinders.
It can be. When the liquid petroleum gas (LPG) is incompletely oxidized due to a reduced oxygen level, CO (carbon monoxide) as well as CO2 (carbon dioxide) is produced. LPG gas is mostly propane and/or butane.
For propane, the comparative reactions are:
(excess O2)
C3H8 + 5 O2 → 3 CO2 + 4 H2O + heat
(insufficient O2)
C3H8 + 4.5 O2 → 2 CO2 + CO + 4 H2O + heat
How is CO produced by burning LPG?
Carbon monoxide is released in the combustion of liquid petroleum gas due to the incomplete oxidation of some fractional components, including propane, when a buildup of exhaust gas reduces the oxygen available to the flame. Almost all of the gas released by properly functioning heaters is carbon dioxide, and heated carbon monoxide may be carried away through a vent or exhaust.
For propane, the comparative reactions are:
(excess O2)
C3H8 + 5 O2 → 3 CO2 + 4 H2O + heat
(insufficient O2)
C3H8 + 4.5 O2 → 2 CO2 + CO + 4 H2O + heat
How hot does LPG gas flame get in a gas burner?
For a common diffusing gas burner use at home, the flame temperature should be in the order of 1800 - 1900 oC. Optimum combustion with air is 1977 oC but that must be at optimum air:fuel ratio.
Propane is a gas that is similar to LPG (liquefied petroleum gas) in terms of its properties and uses. Both propane and LPG are commonly used for heating, cooking, and powering vehicles.
How much LPG required to boil 1 Lt water?
First, here are a few definitions to establish a common framework for this discussion.
It takes 1 BTU/hr to raise 1 lb of water 1 deg F.
1 liter of water weights roughly 2 lbs, so it takes 2 BTU/hour to raise 1 litre 1 deg F.
Water at home temperature is 60 F, it will boils at 212 F. There is 152 F difference.
1 hour = 60 minutes = 3600 seconds.
So, to raise 1 litres of water from 60 F to boiling at 212 F would require 1*152*2=304 BTU/hour.
This analysis does not take into account any thermal loss (cooling) because the loss would vary based on outside temperature, material of the vessel, surface area of the opening, etc. Regardless if you use electricity or propane, insulating your hot liquor tank and brew kettle will help you achieve your target temperature more quickly and maintain that temperature with less energy.
Generally speaking propane burners are rated on BTU/hour or simple BTUs. They range from 35.000-200.000 BTU/hour. This is the amount of energy produced by burning the propane, but not necessarily transferred to heat the water. So, it is not a perfectly efficient transfer to your HLT or boiling kettle. There will be further loss from the vessel itself since it is not a perfect conductor. It is difficult to determine the actual amount of energy produced by the burning propane that actually makes its way into heating the water. Therefore, I will make an assumption that only 50% of the energy produced by a propane burner actually heats the water. A quick google search turned up the King Kooker turkey fryer produces 54K BTUs/hr. Adjusting for efficiency, the propane burner provides 27,000 BTU/hr (from 54,000*50 % per hour). Based on this value, the propane burner could bring 2 lbs of 60 F water to boil at 212 F in (304/27,000*3600 seconds) = 40.53 seconds. Obviously, a more powerful burner will heat water more quickly, but with greater fuel consumption.

What is the LPG mixture in the Philippines?
In the Philippines, the typical LPG mixture comprises mostly of propane (typically around 60-65%) and butane (around 35-40%). This blend is designed to provide efficient energy output for cooking and other household uses.
Why does LPG gas stove is giving out a yellow flame?
There's not enough air (oxygen) in the gas-air mix. Often gas stoves have an adjustment that allows you to adjust the mix. Adjust the mix until the flame is entirely or almost entirely free of yellow.
What type of gas LPG paramagnetic or diamagnetic?
Most gases are slightly diamagnetic and repelled out of a magnetic field.
What is the pressure in domestic LPG cylinder in India?
If you are asking what pressure you should have entering the house it would be 10-11" WC (inches of water column) approximately with all appliances lit. I usually set regulator at 12" with nothing on and check for 10-11"wc at appliance burner manifold. The pressure in the tank is high. not sure I don't own a Gage to check. it will damage a water column psi Gage.It will blow the water out of a wc manometer. Some applications require a main regulator that feeds several smaller regulators and is usually set @ 10lbs or so. leave that one alone if you don't work for the propane company. A psi of <10" will cause a weak flame and suit build up. CO levels should be checked to make sure you don't asphyxiate anyone.
rule of thumb on a lp furnace residential type. under 10 years old. is tighten the regulator screw all the way in and back off a quarter turn on the furnace control valve inside the appliance to get the cleanest flame. I hope I helped. If you haven't had experience with LP gas be very careful. It is heavier than air and will linger in ambient. I have lost eyebrows and eyelashes.
These other guys make sense It is used in some refrigerants. I suppose the pressure coincides with the temperature. sometimes when I bbq the tank gets cold condensation and the flames are weak .
How does LPG gas burning on gas stove involve chemical and physical changes?
When LPG gas burns on a gas stove, it undergoes a chemical change as it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This is a combustion reaction. The physical change involved is the change in state of the gas from a liquid to a gaseous form as it is released from the cylinder and then burns.
LPG is better than Coal in the following points:
- It can be easily transported to our homes through pipelines.
- It has a high calorific value.
- It does not leave a solid residue and neither forms harmful gases.
- It is easy to store.
- It is readily available.
- It has a low ignition point.
- It burns at a moderate rate and its combustion is controllable using a knob.
Hope this helps..!!
How gas convert from liquid to gas form in lpg gas cylinder?
The liquid in an LPG cylinder vaporizes into a gas due to the increase in temperature and pressure when the gas is released from the cylinder. As the gas escapes through the valve, it expands and absorbs heat from its surroundings, causing it to vaporize into a gaseous state. This conversion process allows LPG to be used as a fuel for various applications.
Is Burning of LPG physical or chemical change?
Burning of LPG is a chemical change because it involves a chemical reaction between the LPG (composed of hydrocarbons) and oxygen in the air to produce heat, light, and new substances like carbon dioxide and water vapor. The original LPG molecules are transformed into different molecules during the combustion process.
