Abstract
This article is concerned with the automation of the experimental examinations of the phase states of multicomponent hydrocarbon systems. Experimental examinations of the mixtures of natural gas and gas condensate from the gas-condensate field on the PVT-installation have been performed to determine if the composition of the hydrocarbon mixtures influence the regularities of their phase changes. The comparison of the calculations by means of the REFPROP software package with the experimental data of Russian and foreign authors show that this software program can be used for automatization of the estimated calculations of the phase balances in the range of low temperatures as well as for controlling of the critical parameters of hydrocarbon mixtures. The authors demonstrate the possibility of the REFPROP software package application for choice automation of the hydrocarbon mixture composition for transportation in the low-temperature pipelines in the chosen range of temperatures and pressures.
