LPG and Pollution

January 6th, 2011 No Comments »

LPG is albeit considered to be a clean fuel, there is some pollution which can be associated with the use of LPG. To understand this, let us take a look at the emission from Liquefied Petroleum Gas.

· LPG produces about 45% less carbon dioxide when compared to diesel. It also produces 33% less carbon dioxide when compared to petrol.

· LPG is also said to result in lesser hydrocarbon emissions. It is known to be lesser by almost 70% in comparison with diesel and 40% in comparison with petrol.

· Also, sealed LPG tanks are also known to eliminate spillage and it is known that refuelling LPG is a major source of hydrocarbon emission. To safeguard this, special valves meant for refuelling are suggested.

· When LPG is used in vehicles, they are known to produce lesser Nitrogen Oxide. When compared to petrol, it is lesser by almost 82%. The best comparison is said to come from diesel. LPG is considered to be 99% better in terms of emitting nitrogen dioxide.

· LPG results in 63% lesser carbon monoxide and this is also a great advantage.

· Again, going back to vehicular emission, LPG is considered favourable since it has a lower proportion of benzene as well as butadiene, when compared to those vehicles which run on gasoline.

· There are many green activists who argue that LPG cannot be termed as a green fuel since it results in the emission of carbon dioxide on burning.

Yet, when we compare LPG to other fuels, it is found to be truly better for the environment. It does not result in very high proportion of CO2 emissions. LPG also burns cleaner than diesel or petrol. The argument for or against LPG still continues. What is required to be remembered that LPG is also a non renewable source of energy and hence, the world over, people should always keep in mind that it needs to be used optimally and judiciously.

Disadvantages of LPG Uses

January 5th, 2011 No Comments »

LPG is said to have some properties which makes it dangerous to handle it. Although the advantages of using LPG far outweigh the disadvantages, it always helps to know how LPG usage can also cause some disadvantages.

The main disadvantage associated with the usage of LPG is to do with the storage and safety. To store LPG, you require very sturdy tanks and cylinders. The gas has to be kept pressurized to accommodate it in 274tines lesser space. This can also be perceived by the number of cases LPG cylinders have exploded and resulted in serious damages to lives and property.

In colder climates or conditions, there is a known problem related to starting due to the low vapour pressure of propane. This is known to happen in conditions with sub 32 degrees Fahrenheit temperatures.

LPG is also known to be more expensive than CNG or gasoline.

Disadvantages of LPG Uses When it comes to using LPG in vehicles, it is known to shorten the life of an engine. This is due to the fact that LPG lacks combustive properties with lead and lead substitutes. Also, LPG is not safe to be used in vehicles running or plying on rough terrains and mountain roads. An LPG run car is less powerful than the car which uses diesel or petrol, since LPG is known to have low energy density.

Also, with time, it has been noticed in some Asian countries that as LPG uses have gained popularity, the prices have also been increased. The initial installation fees with respect to equipments and an LPG connection for domestic uses is also priced higher. But yes, LPG is far much cheaper in the long run.

LPG boilers and gas stoves also need regular maintenance to ensure that they are running efficiently. Also, there has to be increased awareness yet to be created with regard to safe storage of LPG cylinders in domestic properties.

Today, LPG fitted cars are very common in countries like Italy, Japan, Austria and Canada. But still, when you compare this usage to petrol or even gasoline, LPG is way down the number chart since it is not easily available in many parts of the world. Also, many people feel that the initial cost of conversion for switching to LPG fuel is very high with respect to domestic vehicles. It leaves lesser boot space in the cars.

Since LPG is highly inflammable, it is potentially very hazardous. It also damages valves of the vehicles. Transporting LPG is also not very easy.

Properties of LPG

January 5th, 2011 No Comments »

Liquefied Petroleum gas, or LPG as it is better known as, is a hydrocarbon. It contains propane, butane, propylene and butylene. Since it is an inflammable mixture of all these gases, it has to be stored carefully. The various properties of LPG are:

· It is a good mixture of gases, mainly constituting Propane and Butane.

· It has a simple structure in chemical terms.

· It is one of the cleanest of all alternative fuels.

· It is a liquid under normal pressure but at ambient conditions, it is found to be gaseous.

· LPG in vaporous form is two times heavier than air.

Properties of LPG · The boiling point of LPG normally ranges anywhere between -42 degrees to 0 degree. The boiling point depends on what proportions are Butane and Propane present in the mixture.

· LPG is almost colourless and has to be stored as liquid under pressure.

· Its weight is about half that of the same volume of water.

· Ethyl Mercaptan is another product which is used to detect LPG leaks. It works like odorant and helps to know when there are LPG leaks.

· LPG’s Flash point is -76 degrees Fahrenheit.

· LPG is essentially a non toxic substance but it can be dangerous if not handled carefully.

· LPG is also known to cause suffocation.

· It is mildly anaesthetic and can be harmful if it is found to be present in high proportions.

· In spite of its anaesthetic properties, LPG has never been used or considered safe enough for medicinal purposes.

· The ignition temperature of LPG is found to be in the range of 410 to 580 deg Celsius.

· It is also known that liquid LPG has resulted in cold burns to human skin since it causes vaporisation at a very fast rate.

LPG Conversion and LPG Kits

January 5th, 2011 No Comments »

With fuel prices like diesel and petrol perennially on a rise, many people have started recognizing the benefits of LPG as an alternate source for car fuels. In some places of the world, it is considered to be the third most important transportation fuel. LPG conversions have many advantages and the top most advantage is of course, saving costs. Also, LPG does not contain any lead or carbon deposit and hence, it is not as harmful as petrol or diesel when it comes to the environment.

LPG Conversion and LPG Kits LPG kits or conversion kits have also become popular today amongst people who want to switch to using LPG instead of petrol or diesel. An LPG conversion kit is made up of mostly aluminium alloy which makes it sturdy and durable. Many LPG providers and suppliers also offer these conversion kits at competitive prices. They offer their expert know-how and services also.

The main components of an LPG kit are a vacuum reducer, a solenoid, change-over switch, emulator, electronic reducer, vertical drain system, valves and gauges. The change-over switches are available in attractive shapes since they are visible on the dash board of the car. The switch helps you to run the car on the two modes, petrol/diesel and gas mode. The solenoids are magnetic valves and are generally made up of brass.

Presently, there are many automobile companies which offer vehicles that run on both petrol/diesel as well as LPG. These are known as duo or dual-fuelled cars or vehicles. Such vehicles contain switches which allow manual conversion from LPG to petrol and vice-versa. Most countries still do not have companies which offer vehicles that run solely on LPG power.

With the right LPG kit, there should be no problem in the conversion process and car owners do not find any difficulty in maintaining such vehicles. For those who want to make the most of LPG fuel, should opt for high quality conversion kits that deliver high performance as well as demand low maintenance. You should opt for LPG kits which are manufactured under strict quality controls or have the ISO certification.

The Future of LPG in India

January 4th, 2011 No Comments »

With many countries like the United States, Italy, Germany, Japan and Canada to name a few switching over to LPG fuel, India does not want to be left far behind. Already, the Indian government has started spreading awareness with respect to the benefits of LPG gas. Many government regulations have also made it mandatory for some public vehicles as well as private ones to use CNG or LPG as the preferred fuel. Not only are these fuels cleaner and greener, they offer the users multiple benefits. LPG has already been established as a highly versatile fuel which can be used across industries and domestic sectors alike.

The Future of LPG in India The future of LPG in India is set to be promising. With more and more people coming to terms with the fact that they need to do their bit to reduce carbon emissions and protect the ecology, LPG usage has also increased and spread.

The domestic as well as industrial uses of LPG are on the rise and hence the LPG imports are also seen to be increasing, in order to meet the demands. Many fuel and power companies are also set to increase their infrastructure as well as supply with respect to LPG. GAIL and Indian Oil are just the few apart from ONGC. But yes, again and again, the point worth remembering is that LPG is also a non-renewable source of energy and hence proper care should be taken not to misuse it.

Domestic as well as commercial connections for LPG are also seen increasing with each passing year. Yet, there has also been a steady rise in the LPG prices since the demand and popularity of this clean fuel has also increased manifold.

In spite of it being proved to be a better fuel in comparison with diesel and petrol, there is yet to be done in order to spread more awareness with the use of LPG in cars and small vehicles. Also, people should be educated and informed about the safety norms associated with this fuel which would help them prevent accidents and disasters caused due to incorrect use of LPG.

Lpg Conversions

January 3rd, 2011 No Comments »

Many of the unleaded petrol engine vehicles can be converted to run on auto gas. The cost that you will incur in the recoupling can be covered in two years. Auto gas is the term used generally for Liquefied petroleum gas (LPG), when it is used for the propulsion of the road vehicles. When compared to the petrol, petrol has high-octane content. The calorific value of LPG is higher due to which the power generated is higher compared to petrol. This implies that one litre of LPG will produce more energy than similar quantity of petrol. The use of LPG instead of petrol will not create carbon deposit inside the engine due to which engine life becomes longer.

Lpg Conversions LPG certainly has certain competitive advantages over the other commonly used automotive fuels. The smoother combustion of auto gas results in higher-octane content. Unlike other fuels, no additives are required. Auto gas contains no lead and is therefore much cleaner. It is much better than petrol because the LPG reaches the engine in pure gas form which in turn results in better combustion. By the use of LPG, life of the engine is extended. This is because of the absence of acids and carbon deposits. The engine oil does not become diluted and thereby reducing the servicing cost. The other advantage is that there are no starting problems unlike diesel. Engine performance is almost same as like petrol.

There is no pilfering and is even much safer than petrol.
Petrol can easily be adulterated with kerosene and malpractice’s are possible in quantity, where as in L.P.G. adulteration is very difficult while on the other hand petrol can be easily adulterated and malpractice is possible.LPG is being used as alternative automobile fuel for more than 45 years in Europe. A wide range of manufacturers such as American car companies like Ford, General Motors and Daimler-Chrysler are offering propane-powered options on some models.
Typically, you won’t find these cars on the showroom floor — they have to be special ordered.

Lpg Hydrometers

January 2nd, 2011 No Comments »

Lpg Hydrometers A hydrometer is an instrument for measuring some characteristics of a liquid, such as its density (weight per unit volume) or specific gravity (weight per unit volume compared with water).

Hydrometer consists essentially of a weighted, sealed, long-necked glass bulb that is immersed in the liquid being measured and the depth of flotation gives an indication of liquid density.

In order to determine the specific gravity of liquefied petroleum gases such as propane and butane and other light hydrocarbons under vapour pressure conditions corresponding to the temperature of the liquid. The cylinder used for measurement is constructed by using a clear plastic barrel. The barrel is held between aluminum end plates with tie-rods.

The working pressure is usually 200 psi. The relief valve is attached and measures this pressure.

Alternatives To Lpg

January 1st, 2011 No Comments »

Alternatives To LpgThe LPG is produced from the hydrocarbons and thus the Liquified Petroleum Gas remains one of the cleanest fuels. The other advantage is that it is also one of economic fuel available in the market.

It rejects nitrogen oxide 95% in less and CO2 10% in less when compared to the gasoline. Though LPG is considered as the most stable and mature alternative fuel available at present but there are a number of other important developments in the alternative fuels area.

But the significant thing is that these alternatives to LPG are currently in their infancy. But there is a possibility that they may well pave the way for cleaner and more efficient fuel than LPGs.

But the fuels that are being tested need significant development so that they become an alternative to LPG, petrol or diesel.

Advantages Of Lpg

LPG has numerous advantages when compared to the other fuels available.

image With its high energy output, instantly available heat, flexibility in use and environment friendliness has become an important alternative energy source.

It offers the following advantages:

  • Lower fuel consumption
  • Cleaner fuel leading to lower maintenance cost and clean environment
  • East and flexibility of control and regulation
  • Combustion with no carbon deposits as the air/gas ratio is the lowest
  • Increased productivity on account of higher throughput and reduced rate of rejections
  • Low running cost due to reduced manpower requirement
  • Safe fuel with narrow flammability range

LPG Auto Gas as Clean Fuel Alternative

December 15th, 2010 No Comments »


LPG scores over traditional sources of automobile fuel considerably both in terms of eco-friendliness and also commercial viability. Modern cars are built with an efficient system that can run by burning traditional forms of fuel. LPG Auto Gas

When manufacturers of these super efficient automobiles are placed with the question of environmental friendliness; they struggle to find an answer to reduce amount of carbon foot print these automobiles are creating. Even with catalytic converters which do reduce some of the carbon footprint, they inherent damage that is done to extract the platinum that is used to build these converters outweighs the advantage that is obtained from them.

Until and unless the time some one invents a catalyst that can simply split the composites of water into hydrogen and oxygen and thereby providing the cleanest and the purest form of fuel energy we will have to make do with something that is the next best both in terms of environmentally clean and commercially viable energy.

Emission rates in LPG

LPG is mostly composed of propane and butane which reaches the combustion chamber in a pure form, burning uniformly and also at a high octane, thus this fuel is highly combustion efficient. Moreover, LPG does not create a high amount of carbon dioxide. It reduces the carbon dioxide emission by 10-15%. Carbon dioxide is one of the main green house gases thus it evidently reduces the green house effect to a large extent.

Auto LPG also reduces significantly the emission of Sulphur dioxide. It also reduces nitrous oxide emissions by a significant margin of 80%. It also reduces particle emission to a level of zero.

LPG can; if opted by most vehicle users; over the years reduce the harmful effects caused by auto emission. In today’s world where most of the European countries and the US are vying for reversing the terrible effects of the green house gases; LPG is the best option to bolster that effort.

Storage and inherent risks of using LPG

In terms of commercial viability also LPG scores over both Petrol and CNG. LPG is easily transferable and can be stored in stand alone infrastructure. The storage and dispensing equipments can be easily operated. In most European countries LPG costs cheapest compared to CNG and Petrol. Unlike in CNG where costly pipes are to be fitted to transfer the gas; this is not the case with LPG.

As far as safety is concerned it as safe as cooking LPG. Any combustible fuel needs inherent safety to be undertaken while using it. Much like cooking gas which is used in our day to day use at home for cooking or heating purposes, safety has to be taken to use it without any accidents. However in the case of LPG the gas is easily dispersed into the air and it needs a compressed dense quantity with a relative temperature of 400 – 500 degree centigrade to explode or catch fire. That’s the reason why after turning the knob one has to hit the switch 2-3 times in order to catch fire. Further stringent safety norms as laid by the Bureau of Indian Standards are followed to manufacture and quality test the Retro Fitting equipments to see if they are fit to be used in an automobile.
