Understanding The Differences Between CNG VS LPG VS LNG

The Federal Government announced that  by next month it will commence the conversion of cars and generating plants for gas fuelling. This was made known by the Minister of State for Petroleum Resources, Timipre Sylva who had always insisted on the need to provide alternative fuel that will be cheaper and clean for the populace.

Nigeria has the three gases in abundant and they will prove better alternative and cheaper options to white products.

According to the minister, the Federal Government plans to convert the vehicles as they can be made hybrids with necessary devices and calibration. He mentioned that the exercise will be free of charge as a measure to ease the impact of the recent hike of petrol pump price on the people..

That means vehicles can  either use gas or petrol as the case may be. What will be available at the gas stations for anyone to buy would be LPG (Liquefied Petroleum Gas) , CNG (Compressed Natural Gas), and LNG (Liquefied Natural gas).

This will require provision of infrastructure and manpower for the policy to succeed. More gas stations will be built and  technicians needed to be trained to handle the conversion.

You need to update yourself with the various types of natural gases and consider expanding your career in this field if you are an experienced auto mechanic or generator technician

At this point we culled from ut.edu CNG VS. LPG VS. LNG FUEL: UNDERSTANDING THE DIFFERENCES

Keep reading to learn the basics of CNG, LPG and LNG fuel and how these natural gases are impacting the industry and the future of your career.

What is CNG Fuel?

In the diesel industry, you will hear the acronym CNG used quite often. You may have even seen the blue diamond CNG sticker on commercial vehicles and mass transit busses and wondered, “What is CNG gas?

CNG stands for compressed natural gas. It is the gaseous product of petroleum and is the first product that is separated during the distillation process. CNG is odorless, tasteless and non-toxic, and is made up of 93.05% methane, nitrogen, carbon dioxide, propane and traces of ethane. It is an environmentally clean alternative fuel, as its combustion process emits a lower percentage of greenhouse gases when compared to other fuels.

While CNG fuel won’t give you the same amount of power that would come from diesel fuel, it certainly has its advantages. CNG has a high octane rating that provides a high compression ratio and is adaptable to modern engines. The combustion of CNG produces less carbon monoxide, hydrocarbons and oxides of nitrogen. Overall, this type of gas can help in reducing pollution, as it is a clean burning fuel.

Understanding LPG and LNG Fuel

In addition to CNG fuel, LPG and LNG are two other common alternatives to gas and diesel fuel. Each of these types of fuels have both similarities and differences.

LPG fuel, or liquefied petroleum gas, is a liquefied gas and is a byproduct derived while extracting crude petroleum. LPG weighs twice as much as air and is colorless, odorless and is a highly flammable explosive gas. It is comprised of propane mixed with butane, traces of propylene and butylene.

One of the advantages of LPG is that it emits less hydrocarbons, carbon monoxide and oxides of nitrogen. It also has a high octane rating and increases engine longevity. The fuel weight-to-mileage of LPG is equal to that of gasoline-operated vehicles.

LNG fuel, or liquefied natural gas, is a natural gas converted to liquid form through liquefaction. During this process, natural gas is cooled at low temperatures until it turns into a liquid, and the volume of gas is reduced by approximately 600 times.

LPG is comprised of 95% methane, and other components include nitrogen, ethane, carbon dioxide and propane. It is non-toxic and non-corrosive, resulting in less pollution. It occupies 1/600 the volume as natural gas, making it much more cost-effective for storage and transportation.

CNG vs. LNG Fuel

While liquefied natural gas and compressed natural gas are similar, their delivery and storage methods are different.

LNG is frozen in order to turn it into liquid form, whereas CNG is pressurized to the point where it is very compact. LNG takes up less storage space on a vehicle than CNG, and it also offers an energy density that can be compared to diesel fuel. This makes it a common choice among many long-haul trucking companies. Using proper procedures, LNG can be converted to CNG.

On the other hand, CNG is easier to refuel than LNG, which requires special handling and equipment. CNG is also very light, so if there is a leak, it will dissipate. It has an unlimited hold time, so even if it goes unused, there is no fuel loss. This makes CNG a safer choice over LNG. CNG also has lower production costs than LNG.

CNG vs. LPG Fuel

CNG and LPG fuel also have both similarities and differences. While CNG is comprised of methane, LPG is comprised of propane and butane. CNG is typically used as a substitute for gasoline in automobiles, while LPG is often used in the industrial, refrigeration, agricultural and catering industries. It is also used to power cooking and heating in homes, and like CNG, can be used as automobile fuel.

CNG releases less greenhouse gas, while LPG releases carbon dioxide, but is still cleaner than gasoline. In the case of a spill, CNG quickly dissipates, whereas LPG will settle on the ground. In general, CNG is considered safer than LPG, since LPG is difficult to disperse.

How Does This Apply to Your Career?

Knowing about the different types of alternative fuels can benefit you greatly in the emerging opportunities. There is going to be growing demand for technicians who are able to work on applications that run on these fuels, but not enough candidates who have the right skills. Cease the opportunities and get some skills.
