After more than 9 months of stable operation, the coke drum tower order control and safety interlock system of the Yanzhou Petrochemical delayed coking unit passed the expert appraisal organized by the China Petrochemical Corporation. Experts believe that the system adopts a step-by-step control design concept, which realizes man-machine interaction and achieves automatic sequential control and interlocking of the operation of the coke drum tower system. It is of great significance to increase the production capacity of the coking unit.

this new material and microfiber, non-woven fabric and other substrates combined, processed and prepared, suitable for a variety of industry applications. Silicone leather using solvent-free technology, silicone coating bonded on a variety of substrates to make leather. Belongs to the 21st century development of new material industry. Due to the excellent characteristics of silicone leather itself: flame retardant, weather resistance, anti-fouling, easy to manage, skin friendly is not sensitive, anti-mildew and antibacterial, wear-resistant and durable, safe and non-toxic performance is very outstanding, suitable for hotels, 3C, home, cars, children and other major industries. Compared with traditional leather, silicone leather has advantages in hydrolysis resistance, low VOC, no odor, environmental protection and other properties. In the case of long-term use or placement, PU/PVC and other synthetic leather will make the residual solvent and plasticizer in the leather will be released constantly, which is very bad for people's health. Physical and chemical stability: long-term use no yellowing, no aging, anti-UV; High temperature ultraviolet exposure without odor, no harmful gas production; High and low temperature resistance: low temperature unchanged hard, high temperature is not soft (-50~200℃); Gas permeability, Silicone Material with PU, PVC tens of times of gas permeability; Antibacterial, no mold; Good elasticity, feel comfortable; Excellent biocompatibility.

The coke drum of the 1.2 million-ton/year coking unit of Yanzhou Petrochemicals Co., Ltd. is an intermittent operation. In each 24-hour production cycle, two coke drums have to be converted to each other, and at least 11 steps need to be completed manually. Misoperation. In order to improve the level of automation of the plant, Quzhou Refining and Chemicals Co., Ltd. will jointly implement the development and application of the coke drum sequence control and safety interlock system in July 2009, and will use procedures to regulate the operation steps of the coke drum tower. According to estimates, after using this system, the equipment coke cycle shortened from 24 hours to 20 hours, and the processing capacity reached 127% of the design capacity.
