摘要
Of the traditional process representations commonly used by chemical engineers, flow diagrams or Process and Instrumentation Diagrams represent the interconnections between plant items, and mass and energy balances present the flow, composition, and conditions at the inlets and outlets of the plant items. It is only during detailed modelling of particular unit operations does the engineer normally address the physicochemical processes that are happening inside the equipment. The rapid leap from process to plant considerations creates a language barrier between engineers and chemists that potentially slows down process development and gives rise to scale-up problems as the controlling processes are overlooked. A simple representation of chemical processes has been devised that focuses on the controlling phenomena that ultimately should allow processes to be scaled-up much more easily.

常用的化学工程师，流程图或过程和仪表图的传统过程表示中的表示植物项之间的相互联系，以及质量和能量平衡给出的流动，组成和条件在工厂项目的入口和出口。只有在特定的单元操作是否正常工程师应对正在发生的设备内部的物理化学过程进行详细建模。从过程中迅速蹿种植方面的考虑创建的工程师和化学家之间的语言障碍的可能减慢工艺开发，并引起规模化问题的控制流程被忽视。化学过程的简单表示已经制定了侧重于控制的现象，最终应该允许进程扩大规模，就更加容易。
