Process Equipment Assemblies (PEA) are pre-designed equipment sets which are selected instead of time-consuming tailor-made design. This paper introduces a new method for the selection and configuration of PEAs exemplified on the unit operation distillation. First step of the new methodology is the selection of the most suitable technology applying matching matrices. The matching matrix required for selecting a suitable distillation technology is introduced. Next a process function-based planning approach is executed using so called master block flowcharts (MBF). These technology specific flowcharts contain all possible process functions required for any potential separation task and contain the technology specific main function and technology independent process functions. Considering process boundary conditions and functions already available in the infrastructure, the MBF is reduced to the functions required for the process. Next, concrete PEAs are selected starting with the main function where the separation of the fluids takes place using the PEA operating range as the main selection criterion. A tool required to determine the operating range of a distillation column is demonstrated. Finally, the PEAs for auxiliary functions are selected from a databank.

工艺设备组件 (PEA) 是预先设计好的设备组，它们被选中而不是费时的定制设计。本文以单元操作精馏为例，介绍了一种选择和配置 PEA 的新方法。新方法的第一步是选择最合适的应用匹配矩阵的技术。介绍了选择合适的蒸馏技术所需的匹配矩阵。接下来，使用所谓的主块流程图 (MBF) 执行基于流程功能的规划方法。这些特定于技术的流程图包含任何潜在分离任务所需的所有可能的过程功能，并包含特定于技术的主要功能和与技术无关的过程功能。考虑到流程边界条件和基础设施中已有的功能，MBF 被简化为流程所需的功能。接下来，从主要功能开始选择具体的 PEA，其中使用 PEA 操作范围作为主要选择标准进行流体分离。演示了确定蒸馏塔操作范围所需的工具。最后，从数据库中选择用于辅助功能的 PEA。
