According to China Drying News, butadiene equipment has a surplus production capacity and shortage of raw materials. Yangzi Petrochemical Co., Ltd. purchases and purchases mixed carbon 4 for processing to achieve an increase in production efficiency. For the whole year of 2012, the company processed and purchased mixed carbon 4 and accumulated a total of more than 30,000 tons of butadiene with an efficiency of RMB 100 million.

In September 2011, the butadiene plant of Yangba Company was completed and put into operation. Yangba Company stopped supplying mixed carbon four raw materials to the olefin plant of Yangzi Petrochemical. Yangzi butadiene equipment is often in the state of “fatness” only by supplying raw materials to Yangzi ethylene plant. . To this end, the Yangzi Petrochemical Production and Operations Department proposed the idea of ​​using the excess capacity of the plant and using the mixed-carbon mixed-carbon systems within the system for processing.

From January 2012, Yangzi Petrochemical began to purchase blended carbon 4 from Shanghai Secco for processing; in April 2012, Yangzi Company seized the opportunity for Zhenhai Refinery to overhaul and have a surplus of carbon 4 resources. , Successfully introduced Zhenhai Refining and Chemical Co., Ltd. with 10,000 tons of mixed carbon four resources for processing and realized win-win cooperation.

Yangzi Petrochemical's use of spare capacity for equipment processing can not only maximize the plant's production capacity, maximize the benefits, but also effectively reduce the energy consumption and material consumption of the plant.

In 2012, the premium grade of Yangtze butadiene products reached a total of more than 98.5%, and the qualified rate of Yangdi butadiene products nationwide, provinces, and cities was up to 100%. The product quality was the leading domestic product and became a major domestic butadiene industry. Brand products.
