W artykule przedstawiono wybrane teoretyczne sposoby obliczania drugich i trzecich współczynników wirialnych dla azotu i metanu oraz ich roztworu, celem wyznaczenia wartości gęstości i liczby ściśliwości tych gazów. Otrzymane wyniki poszczególnych modeli porównano z rezultatami przy pomocy programów gazowniczych SGERG-88 i GRS, opartych na wirialnym równaniu stanu. Analizie dokładności poddano cztery składy gazowe: 100% CH4 (dla T = 263,15-323,15 K), 100% N2 (dla T = 260-340 K), 48,4% CH4 i 51,6% N2 (dla T = 291,4 K) oraz 77,41 CH4 i 22,59 N2 (dla T = 380,15 K).

The paper presents theoretical methods of calculating the second and third virial coefficients for: methane, nitrogen and their solutions to evaluate density and compressibility factor of the mentioned gases. The theoretical results of particular models were compared with that produced by computer codes SGERG-88 and GRS developed for the gas industry, which are based on the virial equation of state. Four gas compositions were analysed: 100% CH4 (T = 263,15-323,15 K), 100% N2 (T = 260-340 K), 48,4% CH4 and 51,6% N2 (T = 291,4 K) as well as 77,41 CH4 and 22,59 N2 (T = 380,15 K).
