Effects of Natural Gas Dilution with Hydrogen-Ammonia Addition for Industrial and Domestic Applications

Abstract

This mini-review aims to provide a methodology for practical solutions to improve the existing natural gas combustion through dilution using ammonia/hydrogen/nitrogen for industrial and domestic applications. The dilution of ammonia-hydrogen with natural gas greatly influences its combustion characteristics. The characteristics of natural gas-hydrogen and natural gasammonia are discussed briefly in this mini-review. Soot emission has a severe adverse effect on the environment and human health. A major solution to mitigate this problem is fuel dilution using hydrogen, nitrogen, or even ammonia. Hydrogen is the least emissive fuel which does not produce soot or carbon dioxide. The feasible alternative for emission and soot control is to reduce carbon footprint by fuel dilution.
