AYALA BLANCO, Elizabeth; APARICIO ARIZA, Adriana Alexandra  and  GARCIA SANCHEZ, Carlos Eduardo. Review of calculation of calorific value and dew point of natural gas, and estimating uncertainties. Rev. ion [online]. 2016, vol.29, n.2, pp.87-99. ISSN 0120-100X.  https://doi.org/10.18273/revion.v29n2-2016007.

Natural gas should meet certain requirements that ensure that their production, transport, distribution and consumption is carried out safely. These requirements correspond to the parameters of gas quality inside which are the calorific value and the hydrocarbon dew point. Correct measurement is of vital importance, especially in the custody transfer points, since who delivered as who receives both are interested in knowing the quality of the gas marketed with a high accuracy. This review gathers different forms of measurement of the gas quality parameters selected, from studies found in the literature both in the determination of its value and its associated uncertainty. However, while the works related to the estimation of uncertainty of the calorific value and the hydrocarbon dew point are limited, this review represents a breakthrough in the path of research applied in the proper determination of these parameters and results with greater metrology reliability of chemical quantities of natural gas.

Keywords : natural gas; hydrocarbon dew point; heating value; uncertainty.
