《化工原理》是石油加工专业学生的一门主干课程，是三年级学生由基础理论课向工程专业课过渡的一门技术基础课。学好这门课，对学生顺利进入后续专业课（如分离工程、石油炼制工程等）的学习是非常重要的。掌握一定的化工原理知识对于化工机械、炼厂自动化、应用化学等专业的 “Principles of Chemical Engineering” is a major course for students majoring in petroleum processing. It is a technical basic course for third grade students to transition from basic theory courses to engineering courses. Learning this course is very important for students to successfully enter the follow-up specialized courses (such as separation engineering, oil refining engineering, etc.). Master a certain degree of chemical knowledge of chemical machinery, refinery automation, applied chemistry and other professional
