By examining its chemical composition and physical characteristics, natural gas experts assess the quality and composition of the gas. Measuring the levels of methane, ethane, propane, and other hydrocarbons in the gas falls under this category. The heating value, or the quantity of energy generated when the gas burns, is also measured by experts. Additionally, they check for contaminants including water, sulfur, and nitrogen. Additionally, to fully comprehend the makeup of natural gas, specialists may use cutting-edge methods like gas chromatography and mass spectrometry. The suitability of the gas for various uses, such as fuel for industrial processes or the production of electricity, is determined using this information.
