Yueyang Xingchang Polypropylene Co., Ltd. achieved complete success in DCS transformation

In November 2012, Yueyang Xingchang Polypropylene Co., Ltd. performed technological transformation of the DCS automatic control system on the occasion of the shutdown of the upstream plant. At present, the DCS automatic control system is running smoothly. On December 2, the company officially produced qualified products and produced more than 100 tons of polypropylene products. During this overhaul, Yueyang Xingchang Polypropylene Factory responded positively to Sinopec's “safety, green, and civilized” overhaul call, closely focused on its annual policy objectives, and paid close attention to technical transformation and technical innovation to achieve profitability. By the end of the current production of polypropylene products This is an increase of more than 10,000 tons compared to 2011. Polypropylene plant staff continued to fight in order to successfully close the end of the year.

Grasping the strength of the military and guaranteeing the safety of production Longman Yueyang Xingchang polypropylene plant DCS automatic control expansion project is to transform the original device control system, at the same time, the workshop to extract part of the technical backbone to go abroad to learn DCS operation and emergency Deal with the smooth connection with the DCS transformation project.

After the renovation, the workshop set up a joint school team in time to synchronize with the DCS control display configuration, instrumentation, and computer to advance the joint school process and eliminate instability. At the same time, the professional technicians responsible for the DCS automatic control transformation project are employed to conduct the centralized teaching of the DCS automatic control technology. For the actual operation of the new DCS system, simulation demonstrations are performed for all polypropylene plant employees. Polypropylene Plant took the opportunity of this overhaul and reform, paid close attention to technical training, enhanced staff's actual machine operating skills, organized multiple technical training exercises within the entire staff, and enabled the staff to grasp the new contents of process, equipment and maintenance as soon as possible after transformation. To ensure the success of a drive once, to produce qualified products at a time, to ensure that safety production is full and excellent.

Grabbing technical transformation team Scientific production and development Before reform, polypropylene factory adopts electric three-type instrument control, low automation, labor intensity, artificial insecurity factors, Yueyang Xingchang Bingzhuo "on the one hand and technological transformation, one on hand team construction, With the central idea of ​​"scientific and technological production seeking for development", the DCS automatic control system reconstruction project will be initiated. On the one hand, the aging of the first-line operators is a good solution to the problem of high labor intensity. On the other hand, it largely eliminates people's uncertainties and uses science and technology to ensure safe and stable production.

After the transformation, the new system adopts Yokogawa DCS system control, and the system interface adopts a Chinese panel, which makes it easier for employees to use the new system and familiarize themselves with the new operating methods. In terms of safety, the DCS system has interlocked protection at the key parts and valves, eliminating man-made misoperations with maximum effort.

The excellent operator hired an expert to drive the product successfully. The company invited the technical cadres and engineers of the Synthetic Rubber Division to accompany the production line for the first time to help solve problems, difficulties, and key points for the start-up; workshop leadership and technical cadres Staying in the workshop, optimizing operations, escorting for the early output of qualified products; new students in the workshop, the backbone of the technology, “see the seams,” seize the timing of the experts to accompany the transportation, learning skills, to enhance the DCS operating technology team to add bricks and tiles.

Under the efforts of all employees of the polypropylene factory, the DCS automatic control system successfully produced qualified products; the personnel of each shift group are familiar with the technical essentials of the positions and are fully committed to achieving long-term safety in production, and strive to close the 2012 finals with a winning attitude.
