Piped Natural Gas or Liquified Petroleum Gas

In the realm of energy, two prevalent options for household use stand out, Piped Natural Gas (PNG) and Liquefied Petroleum Gas (LPG). Both provide a convenient and efficient means of powering homes, but they operate on different principles and have distinct advantages.

In this blog, we'll explore:

The workings, benefits, and considerations of PNG & LPG to help you make an informed decision for your home.

What is a gas system?

A gas system typically refers to a network of infrastructure designed to produce, transport, distribute, and utilize natural gas or liquefied petroleum gas (LPG) for various purposes. These systems are essential for delivering gas to end-users, including residential, commercial, and industrial consumers for various purposes. The components of a gas system can vary depending on the type of gas being transported and the scale of the operation.

What is Reticulation and how its used in natural gas?

Reticulation typically refers to the act or process of forming a network, particularly in the context of distributing or arranging something in a network-like pattern. Natural gas reticulation refers to the process of distributing natural gas from a central supply source to multiple end-users through a network of pipelines. This system is designed to efficiently transport natural gas to homes, businesses, and industries, enabling them to utilize natural gas for various purposes such as cooking, heating, and powering appliances.

Piped Natural Gas (PNG)

Piped natural gas, often referred to simply as natural gas, is a fossil fuel composed primarily of methane(CH4). It is extracted from underground reservoirs and undergoes processing to remove impurities such as water, carbon dioxide, sulfur compounds and heavy hydrocarbons.

PNG:

A piped natural gas (PNG) reticulated system is a sophisticated network of pipelines and associated infrastructure designed to deliver natural gas directly to homes, businesses, and industries. This system operates on the principle of distributing natural gas efficiently and safely from centralized processing facilities or import terminals to end-users through an interconnected grid of pipelines.

Infrastructure:

The PNG reticulated system consists of a network of pipelines that transport natural gas from processing plants or import terminals to residential, commercial, and industrial consumers. These pipelines are typically laid underground to minimize disruption and ensure safety.

Key Players:

The PNG infrastructure is developed and operated by various city gas distribution companies, which are authorized by the Petroleum and Natural Gas Regulatory Board (PNGRB). These companies are responsible for building, operating, and maintaining the PNG network within their designated geographical areas.

Consumer Access:

PNG is predominantly used for cooking, heating water, and space heating in residential households. It is also increasingly adopted by commercial establishments (restaurants, hotels, etc.) and industrial sectors (manufacturing units, small-scale industries) due to its convenience and environmental benefits.

Safety Standards:

The PNG reticulated system adheres to stringent safety standards set by regulatory authorities like PNGRB and the Bureau of Indian Standards (BIS). Safety measures include pressure regulation systems, leak detection sensors, and emergency shut-off valves to ensure safe and reliable operation.

Environmental Benefits:

PNG is a cleaner-burning fuel compared to traditional fuels such as coal or biomass. Its combustion results in lower emissions of pollutants and greenhouse gases, contributing to improved air quality and environmental sustainability.

Government Initiatives:

The Indian government has promoted the expansion of PNG infrastructure through policies aimed at increasing energy access, reducing dependency on imported fuels, and promoting cleaner energy alternatives. Initiatives like the Pradhan Mantri Urja Ganga Project aim to connect more cities and regions with PNG infrastructure.

Benefits to Consumers:

PNG offers several benefits to consumers in India:

• Convenience: Continuous and reliable supply of natural gas without the need for manual handling or refilling.
• Cost-Effectiveness: Competitive pricing and stable tariffs compared to other conventional fuels.
• Safety: Enhanced safety features and reduced risks associated with storage and handling of combustible fuels.

Liquefied Petroleum Gas (LPG)

Liquefied Petroleum Gas, commonly known as LPG, is a mixture of hydrocarbon gases primarily composed of propane and butane. It is derived from natural gas processing and petroleum refining. LPG is stored under moderate pressure as a liquid in tanks or cylinders, and it vaporizes into a gas when released into the atmosphere. It is a versatile fuel commonly used for heating, cooking, and powering appliances in homes and businesses.

LPG Reticulation

A liquefied petroleum gas (LPG) reticulated system is a network of pipelines and associated infrastructure designed to distribute LPG from storage facilities to various end-users, such as residential homes, commercial buildings, and industrial facilities.

Why piped natural gas is better than liquified petroleum gas?

Piped Natural Gas (PNG) and Liquefied Petroleum Gas (LPG) serve as essential energy sources, but PNG holds distinct advantages over LPG in several key areas:

Continuous Supply:

PNG is supplied directly through underground pipelines from a centralized network operated by utility companies. This ensures a continuous and reliable supply without the need for manual refills or deliveries, unlike LPG which requires periodic replacement of cylinders.

Cost Efficiency:

PNG tends to be more cost-effective in the long run compared to LPG. Prices for PNG are typically more stable and competitive due to direct supply, whereas LPG prices can fluctuate based on global market conditions and transportation costs.

Environmental Impact:

PNG is a cleaner-burning fuel compared to LPG. It produces fewer greenhouse gas emissions and air pollutants during combustion, contributing to better air quality and environmental sustainability.

Safety:

PNG pipelines are equipped with advanced safety features such as automatic shut-off valves, pressure regulators, and leak detection systems. This enhances safety and minimizes risks associated with gas handling, which is particularly important in residential and industrial settings.

Convenience:

Once connected to the PNG network, consumers enjoy the convenience of a hassle-free energy supply. There’s no need to handle or store bulky LPG cylinders, making PNG a more user-friendly option for households and businesses.

Energy Efficiency:

PNG is highly efficient in terms of energy conversion and utilization. It provides consistent energy output with minimal energy loss during distribution, making it suitable for a wide range of applications including cooking, heating, and industrial processes.

Infrastructure Development:

Investment in PNG infrastructure supports economic development by providing reliable energy access to urban and rural areas. It encourages industrial growth, enhances energy security, and supports sustainable urban planning.

Conclude Thoughts

Both PNG and LPG play crucial roles in meeting energy needs, PNG offers distinct advantages in terms of reliability, cost-effectiveness, environmental impact, safety, convenience, and energy efficiency. These factors make PNG a preferred choice where infrastructure is available, contributing to its growing adoption across residential, commercial, and industrial sectors globally.
