Phase equilibria play a critical role in the manufacturing of alternative fuels, high purity chemicals, petroleum products, and fuel gases. Chemical manufacturers rely on good thermophysical property knowledge to design these manufacturing systems. Bubble-point measurements are essential to determine how chemicals mix and allow for efficient separation during the manufacturing process. Project proposals are sought to further refine and improve the bubble point measurement technique, demonstrate alternative measurement platforms to evaluate phase equilibria data, and integrate modeling/simulation approaches with experimental measurements for more extensive material analysis. New methods to measure phase equilibria in unique ways through the development of new instrumentation and proposals to study specific chemical systems in industry are encouraged.
