Lanzhou Petrochemical's SBR plant material consumption is low

The latest statistics show that from January to August this year, Lanzhou Petrochemical Company rubber plant 150,000 tons / year styrene butadiene rubber plant material consumption value for eight consecutive months than the standard value of 942.92 kg / ton, for seven consecutive months below the original value of 942.55 kg / Tons, equipment consumption hit a record low, reaching the leading level of domestic similar devices.

Since the beginning of this year, the domestic market for styrene-butadiene rubber has become increasingly fierce, and product prices have continued to slump. To this end, Lanzhou Petrochemical Company rubber plant to reduce equipment consumption and energy consumption, continuous improvement of product quality as the most important task of tapping potential and efficiency, focus on the next step to improve the quality of the "first hand chess."

The smooth operation of production equipment and the stable and controlled production process are the key to reducing material consumption and energy consumption. Lanzhou Petrochemical Rubber Factory took this step and strictly controlled the polymerization system process operation and strictly controlled the number of unplanned parking. In addition, they also strengthened the supervision of process indicators. The technicians go to the posts every day to check the implementation of the technical indicators, and check the implementation of the three processes of the input and output material balance, class composition calculation, and utility consumption calculation for each chemical team, and put the key points on controlling production. Tons of rubber consumed by butadiene and styrene monomer. In the first 8 months, the monomer consumption remained at 942.55 kg/ton or less for a period of 7 months. This single unit saved is equivalent to a saving of 281,700 yuan in production costs.

In order to improve the quality of styrene-butadiene rubber, Lanzhou Petrochemical Rubber Factory took 3 measures, namely the stability of the process to attack polymerization "three rates" (ie, conversion rate, Mooney pass rate, benzene pass rate), carefully operating the attack and control pass rate, Strengthen on-site supervision and attack product appearance quality. The 25 quality measures developed by the workshop have all been implemented. Among them, there are 13 conversion rates, 13 stable Mooney control measures and 12 exterior quality control measures for finished products. After the implementation, good results have been achieved and control has continued. Since the beginning of this year, the qualification rate of the central control has reached 96.58%.

In addition, in terms of management, they strictly follow the upgrading of device design values, implementation and control of operating procedures, and education for all employees.
