Natural Gas and Liquid Fuel

Liquefied natural gases (LNG) are methane-based products which are liquefied from natural gases at atmospheric temperature. LNG can also be referred to as Brown gas or Brown’s gas. Lng is used as a transportation fuel but also has some other important industrial applications.

We know very little about the many uses of lng gas. The basic reason behind its use as a transportation fuel is the fact that it has a high energy density. It has the lowest volatility of all fossil fuels and this makes it highly controllable. In addition, it doesn’t produce emissions that are considered harmful to human health. Moreover, it can maintain the identical storage pressure of natural gases for a very long period, thus enabling secure and safe transportation.

The term’baker’s gases’ describes the chemical formulation of LNG. It has the highest boiling point of all gases and is obtained by taking the vapor vaporized organic gases of the sea and converting them to water. The boiling point of the LNG is 7500 degree Fahrenheit, and it remains constant at that level unless deliberately increased or decreased. In contrast, the average temperature of seawater is roughly degree Fahrenheit. Therefore, by increasing or decreasing the boiling point of lng gas, you can increase or decrease the pressure of the steam injected into the steam boiler.

To achieve energy savings, there are lots of ways you can use LNG. It is often compared with natural gases that are combusted in a combustion engine, because in both instances, the source of energy is the natural occurring fossil fuel. But, unlike the fossil fuel, the source of energy in the organic process of burning LPG is LNG. When oil is combusted, oil produces high temperatures, which changes its chemical makeup (becomes thicker and lighter). These changes occur as the fuel is heated to the boiling point, but at a noncombustible manner, so that the fuel does not explode.

When LPG is combusted in an engine, there is a byproduct called methanol that’s formed. As the temperature of the gas increases, so does the amount of methanol released, until there is no more oil produced. In comparison, LPG produces higher levels of waste gas, which consists mainly of byproducts like methane and ethane, and a lesser amount of oxygen. The low oxygen content leads to a lower amount of energy density.

Natural gaseous state energy is used in residential boilers as well as industrial boilers. The combustion process of LPG absorbs a lot of energy when compared with the combustion process of methane gas, which uses only a little bit of energy. Additionally, the temperature that is reached during the burning of LPG is extremely low compared to the temperature that is reached during the burning of methane gas liquids. Moreover, the amount of time necessary for combustion is relatively long, thus increasing the price per unit of energy produced. Since the price per unit of energy produced is greater in the case of LPG than in the case of methane gas, it may be said that natural gaseous state energy is a better alternative, at least over long term.

A good way to understand the differences between the different forms of energy would be to understand their energy density or their capacity to produce energy. Natural gaseous state energy contains high amounts of energy in comparison with methane gas, despite being considerably lower in density. On the other hand, LPG has a very low amount of energy density, thereby proving to be a bad energy content. Consequently, it can be concluded that the ideal form of energy are the one which has a higher quantity of energy density and a much lower quantity of energy content.

There are various kinds of LPG, the most common being the liquefied natural gases (LNG). But many analysts think that LPG is the wrong choice when it comes to liquid gas application because the shelf life of the LPG is relatively short and the emissions generated during fueling are of a significant nature. There is also the question of efficiency of storage and use of LPG. Even though it’s generally believed that LPG is more efficient than methane gas, studies have shown that the extent of efficiency is determined by the temperature of the environment in which the vehicle will be driven in. For this reason, LPG is used where it’s expected to warm up to a certain degree, while the efficacy of methane gas would be contingent on its atmospheric condition at the time of its use.
