Схема процесса с контрольными точками назается PID. PFD назается схемой баланса вещества. Вне основного процесса, приводятся данные о б елс.

Нормативное обозначние, P说法PFD是工艺原则流程图,包含主要的的工艺流程和最基本的工艺控制要求以及物流名称、温度、压力、流量等数据以及换热器、加热炉的热负荷等数据但其仪表方面的信息较少。P&FD是工艺管道及仪表流程图包含管道编号直径材质等设备编号型号和信息以及工艺对管道安装、仪表等安装要求的信息。P&FD最重要的是工艺和仪表两个专业合作的产品包含了详细的工艺流程开停工、事故处理管线等)和详细的仪表控制方案联锁方案。"
