caption_attribution_description: English: K-Values for systems of light hydrocarbons, low temperature range
context_page_description: DePriester Charts provide an efficient method to find the vapor-liquid equilibrium ratios for different substances at different conditions of pressure and temperature. The original chart was put forth by C.L. DePriester in an article in Chemical Engineering Progress in 1953. These nomograms have two vertical coordinates, one for pressure, and another for temperature. "K" values, representing the tendency of a given chemical species to partition itself preferentially between liquid and vapor phases, are plotted in between. Many DePriester charts have been printed for simple hydrocarbons.
