For production planning and for mutual settlements with suppliers and customers it is important to accurately determine the amount of inert gases at all stages of the technological sequence of their extraction. Gravimetric and manometric methods are proposed for estimating the volumes of compressed gases as applied to pure gases and their mixtures. A comparative evaluation has been made of the methods proposed by various authors for estimating amounts of valuable components in compressed gas mixtures based on manometric method. A universal manometric method that allows determination of the amount of neon and helium in compressed gas mixtures with an adequate degree of accuracy has been developed. The reliability of the calculation method has been verified by comparing the calculated volumes of the inert gases with the results obtained by gravimetric method. Based on the developed method and the data on the compressibility of the mixture components, a program has been developed. Application of the developed program simplifies calculations for helium- and neon-containing mixtures.
