DCS applications in the petroleum and petrochemical industries have several years of history, to now have been developed to the fourth generation. DCS technology is mature, reliable performance, software-rich, functional, industrial process control has become the main force.
Petroleum and petrochemical industry applications DCS , ESD and various Instrumentation Architecture, etc. While there is no significant change, but through continuous development and improvement of these products in the functional and performance have been greatly improved. Sinopec Shanghai Petrochemical Company Limited (hereinafter referred to as the "Shanghai Petrochemical"), the Department of Senior Qin Zhongxiong for power in an interview with our correspondents, said: "Despite the current oil and petrochemical industry, the level of automation applications to meet the development needs of the industry, the stability of large systems can be guaranteed, but the large-scale systems need detailed management methods, including the maximum fine the way after-sales service system functions. "
DCS security services in the gradual thinning
DCS applications in the petroleum and petrochemical industries have several decades of history, to now have been developed to the fourth generation. DCS technology is mature, reliable performance, software-rich, functional, industrial process control has become the main force. Shanghai Petrochemical is China's largest refinery integration, highly integrated modern petrochemical enterprises, DCS system has been in their areas of production process control play an extremely important role.
Qin told reporters Vocational High School, said: "Operation Shanghai Petrochemical from the first set of DCS to the present, has nine established DCS supplier Cooperation Relations. "After 20 years of plant evolution, running in the DCS brand mixed, the product itself, a number of brands, a number of times the system maintenance has become Shanghai Petrochemical equipment sector a challenging job." In such a situation, we must consider the professional services provider. "Qin said senior engineer.
Many companies now play a "packaged service" sign, then this "package" for users whether they expected the same,? Qin Vocational High School, said: "While we require suppliers to the hardware in product quality to be improved, other after-sales service must keep up with, I think these two 'packaged' together to meet the basic needs of the user. In Shanghai Petrochemical, each company's products by DCS 'on Paul'. In addition to ordinary system faults, including user system overhaul, the control system to conduct a comprehensive health check, and evaluate the views put forward rectification for our users Reference. "On the future way of DCS products, services, Qin senior engineers that work in depth with a number of problems will appear, which should be on the terms of service before the amendment in time. In short, from the mode of service and improve the service content, and solutions should be refined.
ESD system functions required to complete
ESD (Emergency Shutdown System) as the escort of security systems, applications in the petroleum and petrochemical industry, beginning generally optimistic about the industry. "Application Note ESD broad prospects for development of large space, precisely because it is widely used, so the practical application of many of the problems there." Qin told reporters senior engineers.
Qin Vocational High School that, first of all to improve the system of voting problems, and now most of the system just stop at the software division, if the hardware genuinely redundant fault tolerance, then the overall system reliability will be greatly improved. On the hardware side, Qin Vocational High School that Cajon box is a spare slot, intelligent trend. Many companies now use the alternate slots are non-intelligent to waste a lot of time and human resources. Plate inserted into a card slot to spare intelligent adapter immediately, which not only save installation time, reduces the installation space.
In the ESD system, some traditional applications have also been a great challenge. Can control digital digital, and control the analog; input control can only control input, but can not control the output, such DI / DO control mode specific operation has become very complicated. Qin Vocational High School, said: "Now many companies to reduce costs to users, the new generation of hybrid I / O template came into being. A variety of functions can be achieved in a card-board, greatly reduced the cost of spare parts.
