Engineering Research Equipment Grant: Phase Equilibrium andMolecular Thermodynamics

该项目为两种不同的专门研究设备提供资金。第一个包括建立静态汽液平衡槽的各种设备。该设备将允许测量具有工业和学术意义的各类混合物的汽液平衡，这在特拉华大学目前是不可能的。第二个项目是一个用于与相平衡研究有关的理论和模型的Sun工作站，以及一个用于超级计算机工作的通道。独特性/创新：将获得的汽液平衡数据适用于过程建模、开发和测试新热力学模型以及确定基团贡献方法的适用性的新混合物。目前的设备将研究限制在相对挥发度约为10或更小的混合物。新的相平衡设备将允许这一点的较大扩展，因此，允许考虑许多目前无法研究的混合物。目前，所获得的数据正在用于确定新的基团贡献参数和测试具有工业重要性的基团贡献方法。此外，一些数据直接被工业使用，例如，杜邦公司在设计制造新聚合物的工艺时使用，雪佛龙公司在油藏模拟中使用。

This project provides funds for two different items of specialized research equipment. The first includes various pieces of equipment to build a static vapor-liquid equilibrium cell. This equipment would allow for the measurement of vapor-liquid equilibrium in classes of mixtures, of both industrial and academic importance, that are not currently possible at the University of Delaware. The second item is a Sun Workstation for use in theoretical and modelling related to phase equilibrium studies, as well as a gateway for use in supercomputer work. Uniqueness/Innovation: The vapor-liquid equilibrium data to be obtained are for new mixtures of interest in process modelling, developing and testing new thermodynamic models, and determining the applicability of group contribution methods. Current equipment restricts studies to mixtures whose relative volatility is approximately ten or less. The new phase equilibrium equipment would allow for a large extension of this, and, thus, allow for consideration of many mixtures that cannot now be studied. Currently, the data obtained are being used to determine new group contribution parameters and to test the industrially important group contribution method. In addition, some data are used directly by industry for example, by DuPont in the design of a process to make a new polymer and by Chevron in reservoir simulation.
