Trend 2: MAV becomes a new mode of MAV strategy, which is to implement the integrated strategy of instrument and control system of the whole plant in the mode of the main automation vendor (Main Automation Vendor). It is an emerging type in the petrochemical industry in recent years. Gravel production line automation system construction model. The ultimate goal of using the MAV model is to provide owners with an automated system that is cost-effective, has a long life cycle, and has a low overall cost. In this model, MAV serves as the partner of the project's overall planning and design unit, providing the user with the overall plan, network structure, hardware/software configuration, project management and operating procedures, functional design specification standards, engineering design, configuration, generation, and debugging. Third-party system integration, debugging, operation and maintenance support services and other services. Practice has proved that this model has a variety of advantages, including on the one hand conducive to the overall coordination of the project, on the other hand conducive to the standardization of various interfaces, man-machine interface, thereby achieving multiple production devices, public engineering integrated automation system synchronization; Formulate functional design specifications to ensure the standardization of integrated automation systems; help to manage multiple EPCs at home and abroad; ensure high quality and high level of integrated automation system engineering; facilitate centralized operations management, optimize resources, and reduce life cycle costs. It can meet the challenges and demands of the construction and operation of modern large-scale petrochemical projects.
Petrochemical automation development trend
Trend 1: The level of integrated automation system continues to increase
World-scale plants need integrated automation systems. For the current large-scale integrated refining and chemical companies, in order to cope with global competition and attach great importance to the construction of enterprise informatization systems, this requires the DCS system to break the situation in which it was only a single device control to form an “information isolated island†through the system. Integration enables true plant-wide centralized control, operation and management. At the same time, the current large-scale petrochemical enterprises have large-scale and synchronous production facilities, and the control system scales up to several tens of thousands of points, involving distributed control systems/fieldbus control systems (DCS/FCS), safety instrumented systems (SIS), Fire and Gas Detection System (FGS), Compressor Control System (CCS), Rotating Equipment Monitoring System (MMS), Equipment Package Control System (PECS), Analytical Data Acquisition System (ADAS), Tank Area Data Acquisition System (TDAS), MAS, AMS, ODS, APC, RT-OPT, OTS, etc. This kind of automation control system, to achieve the integration between the control system of the whole plant, put forward higher requirements for the integration level of the automation system. The Tianjin Refining and Chemical Integration Project that has just been put into commercial operation includes 10 sets of refinery equipment, 9 sets of chemical equipment, public works and auxiliary facilities, and off-site engineering. The scale of automation system integration reached about 143,900 points for DCS I/O and about 44,300 points for SIS I/O. With the in-depth application of computer network technology in automation systems, the era of automatic control systems only as "information isolated islands" has passed, and large-scale, integrated automation systems are the inevitable trend of historical development!
