Engineering Research Equipment Grant: Phase Equilibrium andMolecular Thermodynamics

这个项目为两种不同的专业研究设备提供资金。第一个包括各种设备，以建立一个静态汽液平衡细胞。该设备将允许测量具有工业和学术重要性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Sun工作站，用于与相平衡研究相关的理论和建模，以及用于超级计算机工作的网关。独特性/创新：要获得的汽液平衡数据用于过程建模，开发和测试新的热力学模型以及确定群体贡献方法的适用性的新混合物。目前的设备限制了对相对挥发性约为10或更少的混合物的研究。新的相平衡设备将允许在很大程度上扩展这一点，因此，允许考虑许多现在无法研究的混合物。目前，所获得的数据正在用于确定新的群体贡献参数和测试工业重要群体贡献方法。此外，一些数据被工业直接使用，例如杜邦公司在设计一种新聚合物的过程中，雪佛龙公司在油藏模拟中。

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.
