Systematic Procedures for the Design of MultiProduct Plants,Multipurpose Plants, and Plant Complexes

本研究的目标是发展系统的综合 概念评估的程序和捷径评估技术 多产品和多用途工厂的设计，包括 将问题分解为抽象空间的层次结构， 其中层次中的每个级别包含的详细信息比 比它更高的级别，但比它更低的级别详细。 首先考虑解决方案的重要特征，然后 解决方案是通过添加不太重要的细节层来开发的 在以前的水平上开发的部分解决方案。 PI使用这种技术，并已经表明， 在较低层次的层次结构中所做的从来没有反映出来， 以前的决定消除了解决冲突的问题。 合成石油化工过程的系统程序 同时生产多种产品，但 市场需求与产品分布不相适应 在通过反应器的单程中产生的（例如二醇和 胺）将是非常有价值的工艺设计工具。 同样地， 在某些情况下，可能有利的是产生多于一个的 在同一设备中通过不同的化学路线生产产品， 每种产品只在一年中的一部分时间生产。 多用途 工厂通常但不总是以间歇模式运行， 这样的操作。 第三类需要解决的问题 在这个项目中是植物复合体的设计，即设计 生产反应中间体的过程，然后使用 中间体产生最终项目。 制定所有 这些算法将是有价值的，不仅因为一个更 有效的设计程序，但也作为 设计教学工具。

The goals of this research are to develop systematic synthesis procedures and short-cut evaluation techniques for the conceptual design of multiproduct and multipurpose plants which involves breaking the problem down into a hierarchy of abstraction spaces, where each level in the hierarch contains more detail than the level above it but less detail than the level below it. The most important features of the solution are considered first, then the solution is developed by adding layers of less important details to the partial solution that was developed at previous levels. The PI uses this techniques and has already shown that decisions made at lower levels in the hierarchy never reflect back on earlier decisions eliminating the problem of conflict resolution. A systematic procedure for synthesizing petrochemical processes where multiple products are produced simultaneously but where the market demand does not correspond to the product distribution produced in a single pass through the reactor (e.g. glycols and amines) would be a very valuable process design tool. Similarly, in some cases it might be advantageous to produce more than one product by different chemical routes in the same equipment, where each product is made for only part of the year. Multipurpose plants often, but not always, run in a batch mode are needed for such operation. The third category of problems to be addressed in this project is the design of plant complexes, i.e. the design of processes to produce reaction intermediates, and then use the intermediates to produce a final project. The development of all of these algorithms would be valuable not only because a more efficient design procedure would be available but also as teaching tools for the instruction of design to undergraduates.
