These days, home cooks can pick from a wide range of methods. Cooking is a regular responsibility; therefore picking a cooking surface requires some consideration. The correct manner to cook has implications for both human health and the natural world. PNG and LPG are two of the most common fuel sources for stoves.
Hydrocarbons, particularly methane, are the building blocks of natural gas. The energy density is 9MJ/L, and the calorific value around 42-55 MJ/Kg. Natural gas has a lower toxicity level compared to other gases.
It produces fewer harmful byproducts throughout the combustion process as well. Since PNG is less dense than air, it readily disperses into the gas in the event of a leak, lessening the likelihood of a catastrophic event. Let’s learn about the PNG gas advantages and disadvantages
Advantages of PNG
1. Uninterrupted supply
Your home can receive PNG delivery around-the-clock, every day of the year. You can forget about keeping track of when your LPG cylinder needs to be refilled and when it could potentially run out.
Unlike LPG cylinders, which are only available when they are in supply, PNG is always accessible once a connection has been established. You will have constant access to PNG via a pipeline for all of your needs.
PNG is a risk-free choice. Compared to the standard gas delivered in cylinders, PNG has a pressure of only about 21 millibar. Since natural gas is less dense than air, it will quickly disperse into the atmosphere if a leak should occur. However, as LPG is denser than air, it will eventually fall to the ground if a leak should occur. This raises the potential for the cylinder to catch fire.
Pipelines have pressure regulators and safety valves installed at regular intervals for people’s safety. The PNG flow through these pipelines is constantly monitored by control and inspection equipment. Due to the small size of the perforations in the pipe, gas leakage is highly unlikely.
PNG is unquestionably more secure than LPG.
4. Gas booking
When you switch to PNG, you won’t have to worry about scheduling a delivery for your gas cylinder every month. If you turn on the stove at any time, you will find that you have access to gas.
The kitchen is taken up largely by the LPG cylinder. In contrast, PNG’s kitchen space requirements are minimal at best, consisting merely of the pipe.
When using PNG, you get charged based on how much you really use. However, in LPG, there always remains some gas left behind because of the CNG compression process.
PNG has several advantages over LPG. Since we use it so frequently, the stove we choose out is crucial. PNG is the best option if you want to have a stress-free time in the kitchen.
When burned, PNG is amongst the cleanest fuels available, contributing to better air quality. Water and carbon dioxide vapor are the only byproducts of a full combustion of natural gas. These are the substances exhaled with every breath.
PNG consumers don’t have to worry about reserving LPG cylinders or waiting around for the supply man because the gas is always available. Additionally, no extra room is needed for storage. Customers that use fuel for commercial or industrial purposes don’t have to worry about keeping track of fuel supplies or managing their stockpiles.
Disadvantages of PNG
1. Difficult to find
Most of the piped natural gas is extracted from “conventional” rock layers. These locations are excellent for the extraction of natural gas. However, it’s getting harder and harder to locate them. More effort and money are needed to get natural gas from unconventional sources.
However, the ongoing development of new methods and repurposed equipment makes the process of extracting these deposits easier and cleaner.
As was previously noted, “Green” energy can be obtained by the production of natural gas using biogas, decaying waste materials. What is currently seen as a drawback of natural gas will soon cease to be so.
2. Highly inflammable
If an accident involving natural gas, far greater devastation may result. A lack of caution when dealing with a natural gas leak could result in a fire or explosion. It has no discernible form or flavor and can’t be smelled unless a scent is applied.
3. Greenhouse gas emissions
Burning natural gas emits several carbon molecules into the air, including carbon dioxide and carbon monoxide. These gases contribute to greenhouse phenomenon by releasing carbon from the ground into the air. The top carbon-emitting nations have ramped up their efforts to reduce emissions, but substantial progress has yet to be made.
Just like all other fossil fuels, natural gas will run out one day. Since its true reliability is unable to quantified, some experts classify natural gas as a nonrenewable energy source. It isn’t a long-term solution to the world’s energy crises and cannot be used to power the world’s increasing economy. We must think long-term and put our money into a technology that doesn’t run out.
5. Expensive pipelines
Long pipes, unique tanks, and a different plumbing system are required for using natural gas, all of which add up to a hefty price tag. Transmission and transport across great distances are expensive. Pipe leak repairs are a major expense.
6. Difficult to use
Methane is not the only component of natural gas that must be removed before it can be used. This produces a wide variety of waste products, including water vapor, sulfur, carbon dioxide, & even nitrogen, helium in addition to the more familiar hydrocarbons (propane, ethane, etc.).
The decision that must be made in assessing the benefits and drawbacks of piped natural gas is a matter that seeks equilibrium. In the short run, natural gas might be the best option for the globe to reduce its reliance on the depleting supplies of coal and oil.
Consider the consequences of higher natural gas use only in the long run. Constant consideration must be given to the benefits and drawbacks of piped natural gas as part of any effort to progress the development of renewable and sustainable energy sources.
