This study developed an innovative PFD education methodology utilizing an actual practical petrochemical plant and analyzed its effectiveness. The educational pilot plant located in Ulsan, South Korea, is used annually by 300 students and 1000 working professionals. It consists of equipment similar to real industrial settings, including storage tanks, heat exchangers, distillation columns, and pumps. The educational program comprises six lectures, where students learn by connecting actual equipment with PFD. Specifically, it is designed to help students understand the functions and principles of key equipment such as storage vessels, pumps, heat exchangers, and distillation columns in direct relation to the state, pressure, temperature, and material balance of substances in the PFD. To evaluate the educational effectiveness, a survey using a 5-point Likert scale was conducted, measuring changes in PFD comprehension, satisfaction with each chapter, and increase in confidence. The research results confirmed that this methodology is effective in significantly improving PFD understanding for non-majors and new employees. This study presents a new paradigm in chemical engineering education that effectively links actual processes with theoretical representations. It is expected to contribute to talent development and competitiveness enhancement in the chemical process industry.

本研究利用石化企业的实际情况，提出了一种创新的PFD教育方法，并对其有效性进行了分析。该教育试点工厂位于韩国蔚山，每年有300名学生和1000名工作专业人员使用。它由类似于实际工业环境的设备组成，包括储罐、热交换器、蒸馏塔和泵。教育计划包括六个讲座，学生通过将实际设备与PFD连接来学习。具体来说，它旨在帮助学生了解关键设备的功能和原理，如存储容器、泵、热交换器和精馏塔，这些设备与PFD中物质的状态、压力、温度和物质平衡直接相关。为了评估教育效果，使用5分李克特量表进行了一项调查，测量PFD理解的变化，对每章的满意度以及信心的增加。研究结果证实，该方法可以显著提高非专业和新员工对PFD的理解。本研究提出了一种化学工程教育的新范式，有效地将实际过程与理论表征联系起来。预计将有助于化学加工行业的人才培养和竞争力的提高。

Experimentation and/or learning by doing, where students apply and secure concepts gained in other concurrent courses, are an essential intrinsic component to any engineering discipline in higher education. Moreover, practical skills in chemical engineering are important for the formation and development of our students as well as being within the (Institution of Chemical Engineers) IChemE accreditation requirements. To cope with the restricted access to the university laboratories at the University of Edinburgh (UoE) during the academic year 2020–21 (AY20/21) caused by the COVID-19 lockdown, the different Chemical Engineering courses with laboratory components at the UoE made use of a wide range of digital tools including videos, quizzes, assignments, etc. to provide the necessary and relevant learning environment and ensure students could follow the different experimentations online as if they were in the lab. The quality and quantity of digital material and resources created motivated a subsequent development of a detailed step-by-step interactive online preparation experience prior to current in-person laboratory sessions. During this online preparation, students are guided through the introduction, experimental apparatus, risk assessment, start-up and shut-down via videos and videos embedded with quizzes, interactive activities such as fill in the blank and mix and match, as well as assignment submissions. The aims of the online preparation are three-fold: 1. provide the students with a more engaging and interactive mode of deepening their understanding on the experiment to be tackled; 2. furnish the student with a higher level of confidence and preparation prior the actual in-person experimentation; and 3. ensure students prepare and submit the necessary risk assessment before the laboratory session as expected by the IChemE. Overall, an enhancement in the students’ satisfaction when compared to other traditional preparation modes, such as making use of the laboratory manual, is reported. In particular, a 140 % increase in the confidence and practice are highlighted with an 80 % improvement in securing fundamentals, when compared to no preparation or the sole use of the laboratory manual. The better confidence and understanding prior to the laboratory session also played a role on the enjoyable and rewarding of such hands-on experimentation with the consequent better practical preparation of future professional engineers.

实验和/或边做边学，学生应用和巩固在其他并行课程中获得的概念，是高等教育中任何工程学科必不可少的固有组成部分。此外，化学工程方面的实践技能对于学生的形成和发展非常重要，并且符合（化学工程师学会）IChemE认证要求。为了应对2020-21学年（AY20/21）因新冠肺炎疫情封锁而限制进入爱丁堡大学（UoE）大学实验室的问题，UoE不同的化学工程课程使用了广泛的数字工具，包括视频、测验、作业、等，提供必要和相关的学习环境，确保学生可以像在实验室一样在线跟踪不同的实验。创建的数字材料和资源的质量和数量激发了在当前的亲自实验室会议之前详细的一步一步交互式在线准备体验的后续开发。在这个在线准备过程中，通过视频和嵌入测验的视频，填空和混搭等互动活动，以及提交作业，指导学生完成介绍、实验设备、风险评估、启动和关闭。在线准备的目的有三个方面：1。为学生提供一个更具参与性和互动性的模式，加深他们对所要解决的实验的理解；2. 在实际的亲身实验之前，为学生提供更高水平的信心和准备；和3。确保学生按照IChemE的要求在实验前准备并提交必要的风险评估。总体而言，与其他传统的准备模式（如使用实验室手册）相比，学生的满意度有所提高。特别是，与不准备或单独使用实验室手册相比，在信心和实践方面提高了140% %，在确保基础方面提高了80% %。在实验之前，更好的信心和理解也对这种动手实验的乐趣和回报起到了作用，从而为未来的专业工程师提供了更好的实践准备。
