请问HYSYS中，这个名词是什么意思? aspen hysys contains ideal liquid densities for all components in the pure component library. these values are determined in one of three ways, based on the characteristics of the component, as described below: •case 1 - for any component that is a liquid at 60°f and 1 atm, the data base contains the density of the component at 60°f and 1 atm. •case 2 - for any component that can be liquified at 60°f and pressures greater than 1 atm, the data base contains the density of the component at 60°f and saturation pressure. •case 3 - for any component that is non-condensable at 60°f under any pressure, i.e., 60°f is greater than the critical temperature of the component, the data base contains gpa tabular values of the equivalent liquid density. these densities were experimentally determined by measuring the displacement of hydrocarbon liquids by dissolved non-condensable components.详细请看hysys simulation basis手册查看更多
