The Simulation Training System For The Atmospheric And Vacuum Distillation

With the development of the Petroleum and chemical industry, the new technology of the production mechanism to be applied more and more, and tend to be more complicated, the capacity of a single set of device is becoming larger.Large and oversize equipment is increasing, process control systems is becoming more cumbersome and complex.A large set of production equipment is usually controlled by a few individuals.To the personnel’s quality request is higher and higher.So for these operators’ skill training becomes increasingly imporment.And petrochemical simulation training system can solve these problems. Atmospheric and vacuum distillation unit and operators’ skill technical level of the follow-up device has a close relationship with yield, the quality of the products and economic benefit.Developing whole process simulation training system of the apparatus, to ensure smooth and efficient running of plant is of great significance.In some oil refining company simulation training system for the 2.5M/a atmospheric and vacuum distillation as the background,and expounds using the RealSim simulation system development platform develop process simulation system in detail. First with the design of the device data and production data as the foundation, modeling clear idea of the whole process model, referring to the process which the production of the factory, by transfering the original modeles and newly developed unit model, forming a process model of the whole process,to complete the process for the development of whole process simulation model.Then to develop the DCS interface,completing imitation of DCS configuration of flow chart, the configuration of data points.Finally to consummate the simulation training system features:marking system,working condition selections,alarm monitoring,fault Settings etc.Rating system development, including open downtime and accidents to set up and score. Each system via OPC link, complete the communication between each other.The simulation training system to run the test shows that,rational system model has strong machine, the imitation of DCS interface operation is consistent with the actual production of the pilot operating, getting the customer’s identity. By simulating the operation of the whole process of analysis, Throughout the simulation and actual operation of the device is very similar, simulating the actual production device open, stop, normal operation and incident handling conditions of dynamic response, closing to the actual production, having a good dynamic characteristics and a strong practical value. Not only it can be used for simulation and training, but also to explore deeper and expansion.
