Synthetic Natural Gas (SNG)

Synthetic Natural Gas (SNG) is a blend of Liquefied Petroleum Gas (LPG) and diluent. The possible diluents are Biogas, Digester Gas, Landfill Gas, Nitrogen and Compressed Air. However, the commonly used diluent is compressed Air. Thus produced SNG provides the direct replacement for Natural Gas.

The ratio of LPG to diluent (air) will depend on the Wobbe Index of the fuel to be replaced (Natural Gas). Matching the Wobbe Index ensures the two different fuels behave exactly as same fuels and fuel swapping becomes seamless.

SNG & Industry


SNG systems can be virtually designed to meet any energy demand due to its modular nature. It also can be designed to give tailor-made solution to suit specific process requirement. Because of its modular construction and plug and play technology, it can work smoothly in extreme climatic conditions.

National Gas has designed systems ranging from 20 MMBTU/ Hr up to 2000 MMBTU/ Hr for various industries like Steel rolling mill, DRI, Pelletizing plant, Ceramic, Construction material, Aluminium processing, Float glass, Fiber Glass etc.

WHY USE SNG?

SUBSTITUTE TO NATURAL GAS


Natural Gas is a vital component of the world's supply of energy but there is a mismatch in demand and supply leading to scarcity of Natural Gas.

SNG is desirable when there is an absence or a shortage of Natural Gas in a region. SNG can be used to precede the availability Natural Gas or to augment the gas supply where Natural Gas is already available.

ALTERNATIVE FUEL


SNG systems provide a convenient, consistent,high quality fuel with combustion characteristics similar to Natural Gas. In emerging economies where Natural Gas is in its infancy, SNG plants allow local gas utility firms to “build up” a customer base during planning and construction of a Natural Gas transmission line. The availability of SNG also entices commercial and industrial growth since such customers can install Natural Gas equipment before arrival of Natural Gas.
The SNG system can be virtually designed to meet any energy demand due to its modular nature. It can also be designed to give tailor-made solutions to suit specific process requirements in different working scenario.


1. SNG as base Load system: Provide SNG in region where NG is currently not available. SNG baseload system provides continuous and uninterrupted fuel supply to meet full load energy demand.

2. SNG as Standby System: SNG will provide an ideal standby fuel in the event Natural Gas source is unavailable due to curtailment, maintenance shutdown or catastrophic failure or interruption of Natural Gas supply.

3. SNG as Peak Shaving System: SNG Peak Shaving System acts as an asset as well as profit protection tool incase of shortage or inadequate supply of Natural Gas. It willalso help to mitigate price volatility during peak demand period.

SNG systems provide a convenient, consistent, high-quality fuel with combustion characteristics similar to Natural Gas. In emerging economies where Natural Gas is in its infancy, SNG plants allow local Gas utility firms to “build up” a customer base during planning and construction of a Natural Gas transmission system. The availability of SNG also supports commercial and industrial growth since such customers can install Natural Gas equipment and commence their production without waiting for the arrival of the Natural Gas. This way Industries save substantial interest costs by commencing production on time.

The advantages of SNG under specific situations are obvious. One of the benefits of using SNG is that it eliminates re-condensation problems commonly associated with undiluted LPG vapor, as the “tempering” of the LPG with air suppresses the dew point.

WHO CAN BENEFIT FROM SNG?

SNG can be an ideal solution under following situations:


Inadequate Natural Gas supply
No Natural Gas supply
Natural Gas is not available in the region currently but system needs to be designed for Natural Gas to avail future benefits
Natural Gas pricing opportunities
Unique features of SNG system make it an ideal solution for:


Large and Medium scale industries
Avoiding investment in dual fuel Burners
Optimization of Production Capacity
Critical Industrial applications like Float Glass, Fiber Glass, Food, and Ceramic (Where Lance Burners are used)
Low switchover cost and risk
Save in Insurance Premium by using SNG as back up
Utility Companies
Being able to meet peak grid demand by injecting SNG
Hotels / Commercial Complexes
District Cooling / Heating Units
