摘要
化工仿真实训是以真实的工厂单元及工段为背景,用动态数学模型来模拟真实的带有控制点的设备和工艺流程实际操作。通过仿真实训,学生能够身临其境地了解化工过程的工艺和控制系统的动态特性,提高对复杂化工过程动态运行的分析和决策能力,提高他们的理论水平和工程能力。化工仿真实训教学的重点和难点是过程控制,它有利于提高学生对复杂化工过程的分析和决策能力,更能培养学生建立工程意识观。目前,化工仿真软件主要通过质量控制步骤的方式来实现该教学过程。基于此,本文以东方仿真软件的常减压炼油开车过程中的质量控制步骤为研究对象,对影响质量控制步骤的原油进料量进行了详细的分析,为化工仿真教学提供一定的理论指导。
Chemical simulation training is based on software,real factory units and sections as background,simulation machine as tool,real-time running dynamic mathematical model to simulate the actual operation of equipment and process with control points.Through simulation training,students can learn the dynamic characteristics of process and control system of chemical process,improve the analysis and decision-making ability of dynamic operation of complex chemical process,test and propose the optimal operation scheme,and improve their theoretical level and engineering ability.The key and difficult point in the chemical simulation teaching is the coordinated control of the chemical production process.This process learning is not only conducive to improving the students'ability of analysis and decision-making of the complex chemical process,but also to cultivating the students to establish a continuous and stable sense of engineering.At present,chemical simulation software mainly realizes the teaching process by setting quality control steps.Based on this,taking the atmospheric and vacuum refining start-up of Dongfang simulation software as an example,taking the quality control steps in the start-up process as the research object,the key factors affecting the quality control steps,especially the crude oil feed quantity,are analyzed in detail,providing certain theoretical guidance for process optimization,control and related teaching in chemical simulation.
