Abstract
The article is devoted to the development of methods for calculating the thermal conductivity of complex hydrocarbon mixtures such as gas condensates, which are widely used as components for motor and jet fuels. The work was carried out on the basis of the results of experimental studies of thermal conductivity of the eight most representative deposits in Central Asia in terms of group hydrocarbon composition. An analysis of existing equations for calculating the thermal conductivity of liquid petroleum products and the possibility of their use for gas condensates was carried out. A number of new equations are presented for calculating the thermal conductivity of gas condensates depending on the group hydrocarbon composition in a wide range of temperatures and pressures.
