The Advantages and Disadvantages of Natural Gas and Propane Heating
LPG (either Butane or Propane) is the general term given to many chemicals that are commonly found in houses. It is a very versatile fuel and because of this, it can be used for many applications. In the domestic market, LPG is used as a cheaper source of energy than kerosene, which is the main component of aviation fuels. For this reason, LPG is very popular and is available at all places from supermarkets to gas stations.
LPG is produced from crude oil or natural gas
by a process known as cracking or flaring. The natural gas or crude oil is first fed into a compressor where pressure is released; this compressed energy is then stored in a liquid. There are two types of LPG – domestic and commercial grade. The domestic grade is commonly stored and used in the home, whereas commercial grade is usually stored and used in offices and factories.
There are three general requirements for using LPG as fuel.
First of all, the LPG must have a positive freezing point (the freezing point is the absolute level of water vapor in a substance). Next, according to health and safety regulations, all LPG liquid must be treated to avoid any accidental release of toxic fumes or compounds that may prove harmful to humans or the environment. Lastly, when used as cooking fuel, the LPG liquid must be liquefied so that it may be easily added to the cooking vessel.
LPG as a heating fuel
is mainly obtained through burning in internal combustion engines (usually gasoline or diesel) at relatively low pressures. It is released as either a gaseous or liquid form, depending on its specific chemical makeup. Generally, the most common type of LPG that is stored and used in domestic heating systems is LPG liquid (also known as LPG gas or liquefied natural gas), which is stored in cylindrical cylinders.
According to the World Health Organization (WHO)
and the United States Environmental Protection Agency (EPA), LPG is an excellent source of low-cost, clean energy. This clean energy source is highly efficient and effective, with a high capacity of providing heat or illumination. In addition, this LPG can be used in generating electricity through the burning of natural gas cylinders. But despite its advantages, this type of heating oil poses certain hazards to the environment when it releases toxic gases during combustion or any other means of combustion. As such, these types of hazardous emissions must be controlled.
As a substitute for LPG
a commonly used energy source is propane. Propane is highly flammable and also causes many of the same hazards as LPG gas. Therefore, propane tanks must always be placed in an area that is highly ventilated. But even though it is much safer than LPG, it still causes a certain amount of harm to the environment during combustion.
