Monitoring of Phase Distribution when Controlling Safety of Transport Processes and Hydrocarbon Storage

Abstract

Based on statistical processing of an array of information and summarizing the experimental data in IUT, analytical dependences for calculating the coefficient of the phase equilibrium under various pressures and temperatures were obtained. The proposed equations for the first time used the quantitative composition of hydrogen which determines, according to the authors, the volatility of the oil or condensate fraction and greatly simplifies relevant calculations in comparison with known analogues. To find the coefficients a computer program was developed that implements a method of non-linear regression. The developed algorithm was tested and proved to be very convenient and efficient for a rapid assessment of experimental studies.
