Для решения поставленной задачи требуются полученные экспериментально с высокой точностью значения коэффициента сжимаемости природного газа. С этой целью разработана методика и экспериментально определён коэффициент сжимаемости природного газа. Предложенная методика основана на том, что для оценки применимости уравнения состояния достаточно получить относительное значение коэффициента сжимаемости и не определять его абсолютное значение. Такой подход не требует сложного оборудования и обеспечивает высокую точность определения коэффициента сжимаемости. Методика апробирована на азоте, аргоне, воздухе и метане. Неопределённость определения коэффициента сжимаемости не превышает 0,1 %. Экспериментально исследованы два различных состава природного газа. Показано, что неопределённость расчёта коэффициента сжимаемости по уравнениям состояния GERG-2004 и AGA8-DC92 составляет не более 0,1 % при температуре 220–250 К и давлении менее 5 МПа.</p></abstract><trans-abstract xml:lang="en"><p>The actual problem of the possibility of using the equations of state for the gas phase of natural gas at temperatures below 250 K is considered. To solve it, the compressibility coefficients of natural gas obtained experimentally with high accuracy are required. The technique was developed and experimental study was carried out of compressibility factor aiming expanding temperature range of the state equations GERG-2004 and AGA8-DC92. The proposed technique is based on the fact that to assess the applicability of the equation of state, it is sufficient to obtain the relative value of the compressibility coefficient and not to determine its absolute value. The technique does not require complex equipment and provides high accuracy. The technique was tested on nitrogen, argon, air and methane. Uncertainty of determination of the compressibility factor is not greater than 0.1 %. For two different compositions of natural gas, obtained experimental data were demonstrated that the equations of state GERG-2004 and AGA8-92DC provide uncertainty of the calculation of the compressibility coefficient within 0.1 % in the temperature range from 220 K to 250 K and pressure below 5 Mpa.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коэффициент сжимаемости</kwd><kwd>методика</kwd><kwd>эксперимент</kwd><kwd>уравнение состояния</kwd><kwd>неопределённость измерения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>compressibility factor</kwd><kwd>technique</kwd><kwd>experiment</kwd><kwd>equation of state</kwd><kwd>uncertainty</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">TM-15 / The GERG-2004 Wide-range equation of state for natural gases and other mixtures, edited by O.
