Liquefied natural gases (LNG) are methane-based products which are liquefied from organic 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 cause of its use as a transport fuel is that it has a higher energy density. It’s the lowest volatility of all fossil fuels and this makes it highly controllable. Additionally, it does not produce emissions that are considered harmful to human health. Moreover, it can maintain the same storage pressure of organic gases for a lengthy period, thus enabling safe and secure transportation.
The term’baker’s gases’ refers to the chemical formula of LNG. It has the highest boiling point of all gases and is obtained by taking the vapor vaporized organic gases of the ocean and converting them into water. The boiling point of the LNG is 7500 degree Fahrenheit, and it remains constant at that level unless intentionally increased or diminished. In contrast, the average temperature of seawater is approximately 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 a number of ways in which you can utilize LNG. It is often compared with natural gases that are combusted in a combustion engine, because in both cases, the source of energy is the natural occurring fossil fuel. But, unlike the fossil fuel, the source of energy in the natural process of burning LPG is LNG. When oil is combusted, petroleum produces high temperatures, which changes its chemical makeup (becomes denser 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’s a byproduct called methanol which is formed. Since the temperature of the fuel increases, so does the amount of methanol released, until there isn’t any more oil produced. In comparison, LPG produces higher levels of waste gas, which consists mainly of byproducts like methane and ethane, and a lower quantity 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 consumes a lot of energy when compared with the combustion process of methane gas, which utilizes only a little bit of energy. Additionally, the temperature that is reached during the burning of LPG is very 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 cost per unit of energy generated. Since the cost per unit of energy generated is higher in the case of LPG than in the case of methane gas, it can 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 kinds of energy is to understand their energy density or their capacity to produce energy. Natural gaseous state energy comprises 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 poor energy content. Consequently, it can be concluded that the ideal form of energy would be 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 produced during fueling are of a significant nature. There’s also the question of efficiency of use and storage of LPG. Although it is usually thought that LPG is more efficient than methane gas, studies have demonstrated that the degree of efficiency is dependent on the temperature of the environment where the vehicle will be driven in. For this reason, LPG is used where it is expected to heat up to a certain degree, while the efficiency of methane gas would depend on its atmospheric condition at the time of its use.
