Abstract
“ GBT/17747.2 Natural gas-Calculation of compression factor-Part 2 ” refers to the calculation method of “ AGA8-92DC ” equation, which is very accurate for the calculation of conventional natural gas compressibility factor, but in the calculation process, a large number of intermediate variables, positioning parameters and interactive parameters are introduced, which makes the calculation process more complicated. Based on the critical state of mixed gas, a new fitting formula is proposed to replace the binary interaction parameters used in “ PR ” equation, so as to simplify the calculation process. Compared with the original “ PR ” equation and “ AGA8-92DC ” equation, the calculation results of conventional natural gas compressibility factor and acid natural gas compressibility factor are more close to the laboratory measured compressibility factor.
