PŘEPOČET TEPLOTY ROSNÉHO BODU VODY V ZEMNÍM PLYNU

In their article the authors focus on the current methods for determining the temperature of the dew point, which is an important parameter in terms of calculating permissible water content in natural gas both for gas business entities (shippers, distributors, storage operators, traders) and for their customers. The study analyses seven currently used methods of determining the temperature of the dew point (General Eastern's GEI application, J. Dědek's method, the Transgas (TG) formula, Bukacek's correlation under the CSN EN ISO 6327 standard, Antoine equations; Hysys software; and GERG's method); having compared and assessed them, the authors propose two new methods (one based on the Magnus formula and the other for real gases), and describe them in detail in their contribution.
