Resumo: Natural gas is formed by light hydrocarbons, which are often associated with CO2, N2, O2, CO, H2, H2S and noble gases. Among hydrocarbons, methane (CH4) represents the main constituent of natural gas, followed by ethane (C2H6), propane (C3H8), butane (C4H10), pentane (C5H12) and their respective isomers. Natural gas is mainly used in electricity generation (thermoelectric plants) and industrial consumption. In the generation of electricity, it is favoured by good energy efficiency and lower CO2 emission rate. Inmetro is one of the Metrology institutes of South America. NMIs have the mission to establish globally uniform measurement systems for important gases and to support energy priorities, as well as to ensure reliable measurements for the country’s production chain. Carrying out regional comparisons is essential to ensure metrological traceability in the production chain of their countries. Inmetro has participated in the last regional key-comparison of natural gas coordinated under the auspices of the inter-American metrology system, SIM-QM-S5, and this work presents Inmetro´s results.
