Process function-based selection and configuration of Process Equipment Assemblies (PEAs) demonstrated on an industrial process

Process Equipment Assemblies (PEA) based process design is built on selection of designed equipment from a databank instead of a tailor-made design. The first complete PEA-based selection and configuration method, including the main equipment, auxiliary functions and the infrastructure was presented in [1]. The process function-based planning approach uses automated procedures for estimating the operating range of the separating equipment as basis for the selection. This paper demonstrates the whole methodology on the industrial production process of triallyl cyanurate with more than one process step and different unit operations to show the method´s general applicability. As a basis, databanks for the main separation equipment, the infrastructure and the auxiliary PEAs are introduced. Additionally, a comparison of conventional and PEA-based designed distillation equipment showed comparable results and an applicability of the developed PEA-based tools in conventional design.

基于工艺设备组件（PEA）的工艺设计是从数据库中选择已设计的设备，而非定制设计。第一种完整的基于PEA的选择和配置方法，包括主要设备、辅助功能和基础设施，在文献[1]中有所介绍。基于工艺功能的规划方法使用自动化程序来估算分离设备的操作范围，并以此作为选择的依据。本文以氰尿酸三烯丙酯的工业生产工艺为例展示了整个方法，该工艺包含多个工艺步骤和不同的单元操作，以此证明该方法的普遍适用性。作为基础，介绍了主要分离设备、基础设施和辅助PEA的数据库。此外，对传统设计的蒸馏设备和基于PEA设计的蒸馏设备进行比较，结果表明二者相当，且所开发的基于PEA的工具可应用于传统设计。
