Natural Gas and Liquid Fuel
Liquefied natural gases (LNG) are methane-based products which are liquefied from natural gases in 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 transportation fuel is 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 does not produce emissions which are considered harmful to human health. Moreover, it can maintain the same storage pressure of natural gases for a very long period, thus enabling safe and secure transportation.
The term’baker’s gases’ refers to the chemical formulation of LNG. It has the highest boiling point of 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 stays constant at that level unless deliberately increased or diminished. In comparison, 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 a number of ways you can use LNG. It’s 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 from the organic 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 take place as the fuel is heated to the boiling point, but in 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. Since the temperature of the fuel 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 such as methane and ethane, and a lesser amount of oxygen. The low oxygen content leads to a lower quantity of energy density.
Natural gaseous state energy is used in residential boilers in addition to industrial boilers. The combustion process of LPG consumes plenty of energy as compared to 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 price per unit of energy generated. Since the price per unit of energy generated 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 choice, at least over long term.
A fantastic way to understand the differences between 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 much lower in density. On the other hand, LPG has an extremely low quantity of energy density, thereby proving to be a bad energy content. Hence, it can be concluded that the ideal form of energy are the one which has a higher amount of energy density and a lower amount of energy content.
There are many types of LPG, the most common being the liquefied natural gases (LNG). However, 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 storage and use of LPG. Although it’s generally believed that LPG is more efficient than methane gas, studies have shown that the extent of efficiency is dependent on the temperature of the environment in which the vehicle will be driven in. Because of this, LPG is used where it’s expected to warm up to a certain degree, while the efficacy of methane gas would depend on its atmospheric condition at the time of its use.
