![]() Read this K-value off the chart (approximately 21.3). Since hydrogen is such a common component of organic compounds. Second, it should identify and locate any functional groups present in the compound. First, it should indicate how the carbon atoms of a given compound are bonded together in a characteristic lattice of chains and rings. ![]() Note where the line crosses the methane axis. A rational nomenclature system should do at least two things.Connect the points with a straight line.On the right-hand vertical axis, locate and mark the point containing the temperature 60☏.On the left-hand vertical axis, locate and mark the point containing the pressure 100 psia.Example įor example, to find the K value of methane at 100 psia and 60 ☏. Many DePriester charts have been printed for simple hydrocarbons. "K" values, representing the tendency of a given chemical species to partition itself preferentially between liquid and vapor phases, are plotted in between. These nomograms have two vertical coordinates, one for pressure, and another for temperature. DePriester in an article in Chemical Engineering Progress in 1953. DePriester Charts provide an efficient method to find the vapor-liquid equilibrium ratios for different substances at different conditions of pressure and temperature. id construct-an-x-y-diagram-for-flash-distillation (do not remove this text).
