【摘要】：應(yīng)用立方型狀態(tài)方程計算氣液相平衡,求取汽油餾分中烴化合物組分在任意指定溫度下的飽和蒸氣壓,為汽油餾分的氣液相平衡計算提供支持。方程求解通過編程實現(xiàn),輸入?yún)?shù)包括化合物的臨界溫度、臨界壓力和偏心因子,輸出為對應(yīng)溫度下化合物的蒸氣壓。利用該方法可以計算汽油餾分中所包含的400多種烴化合物的蒸氣壓,比較了在37.8℃下的蒸氣壓計算值和實測值,結(jié)果吻合較好,輕烴化合物蒸氣壓的平均相對誤差低于1%,汽油全餾分范圍內(nèi)烴化合物蒸氣壓的平均相對誤差低于4%。
[Abstract]:The equation of state is used to calculate the vapor-liquid equilibrium, and the saturated vapor pressure of the hydrocarbon compounds in gasoline fractions at any given temperature is obtained, which provides support for the gas-liquid equilibrium calculation of gasoline fractions.The input parameters include the critical temperature, critical pressure and eccentricity factor of the compound, and the output is the vapor pressure of the compound at the corresponding temperature.This method can be used to calculate the vapor pressures of more than 400 hydrocarbon compounds contained in gasoline fractions. The calculated and measured vapor pressures at 37.8 鈩，
