Gas condensate columns are used for calculating gas condensate in gas condensate columns using methods for gas properties (volume and pressure drop) for gas wells. The amount of condensate that fits 1 cubic meter of gas is determined in grams after identifying gas condensates, then condensate components are calculated. Initially, the amount of condensate is calculated under multiphase conditions, then the stable amount of condensate remaining in various separation regimes and its fraction composition and density are determined
