Definition - What does Manufactured Gas mean?
Manufactured Gas, also known as artificial gas, is the gas that was produced from coal, oil and coal mixes or from other petroleum products. The manufacturing process typically consisted of the gasification of combustible materials like oil, wood and coal. The materials were heated in ovens which were enclosed in an oxygen-free atmosphere. The gas was generated with the mixture of various chemical substances like methane, ethylene, hydrogen and carbon dioxide. A dense and oily liquid called coal tar condensed out from the gas at several stages during the production, purification and distribution of the gas.
Petropedia explains Manufactured Gas
Manufactured Gas was produced by two processes. The most common, simpler and older process was producing the gas from coal by heating it in an enclosed oven with oxygen-free atmosphere. The elusive components of coal left were removed from the gas and were collected, cooled and then purified before being conveyed for use in the surrounding areas. A new process of artificial gas production was introduced after the gas manufacturing industries were developed. The process produces a mixture of gas which burned brighter and hotter. This process called carbureted water gas was introduced in the 1870s.
