Abstract: Data on the thermal conductivity of industrial gases (vapors) are used in chemical technology, in the processing of oil and gas for analysis, calculation, and design of thermal processes and apparatus (heat exchangers, furnaces). It is believed that information requests for this property can be satisfied due to the data and recommendations for calculation available in the reference literature. Thus, it is of interest to develop a more convenient (modified) approach to the calculation of the thermal conductivity of gases at a “reference” temperature and low pressures, bypassing the aforementioned problems of the Roy – Todos method. Reliable reference materials were used as an information database of the thermal conductivity of hydrocarbons in the gas (vapor) phase. About 40 hydrocarbons representing various classes with molecular weights of 26 … 254.5 were selected. Physico-chemical characteristics of the substances taken according to the data. The article considers the calculation of the thermal conductivity of gases at the “reference” temperature value. The proposed formulas make it possible to determine the temperature dependence of thermal conductivity at low pressures
