Technical Procedures for Using Synthetic Natural Gas as an Alternative to Natural Gas in Different Supply Conditions for Industrial Customers

Abstract

The Synthetic Natural Gas (SNG), as considered in this work, is a blend of Liquefied Petroleum Gas (LPG) and air used to replace Natural Gas (NG). This paper describes different strategies for using SNG as an effective substitute of NG in base-load, backup, and peak-shaving supply conditions to overcome NG supply interruptions from Local Distribution Companies (LDCs) for industrial consumers. The replacement of NG by SNG for industrial uses must deal with technical difficulties, which do not always allow both gases to be immediately exchangeable. The authors point out some of the difficulties involved in the process and propose ways to overcome them during a gas replacement process.
