"12th Five-Year" ethylene industry has a strong driving force

The reporter learned from the China Chemical Industry Economic and Technological Development Center on August 29 that during the “Twelfth Five-Year Plan” period, a batch of large ethylene projects will be completed and put into operation in Wuhan, Pengzhou, Fushun, Daqing, Huizhou, Zhanjiang, Yangzi, etc., plus some Capacity expansion projects have been put into operation one after another. It is expected that by 2015, ethylene production capacity will reach 21 million to 22 million tons, and carbon V/C9 resources will reach approximately 2.6 million tons and 2.2 million tons respectively. At present, the comprehensive utilization of carbon V/C9 downstream is quietly heating up.

According to Ma Cong Yue, deputy director of the China Chemical Industry Economic and Technical Development Center, as of the end of 2010, China's inland cracking ethylene production capacity has reached 14.58 million tons, and the current year’s output was 13.8 million tons, and the cracked carbon V/C9 resources were approximately 1.6 million respectively. Tons and 1.3 million tons. Faced with such a large amount of carbon V/C9 resources, large companies such as PetroChina and Sinopec are accelerating their own pace of resource integration and comprehensive utilization. At the same time, private enterprises represented by Luhua, Yuhuang, and Jinhai Deqi are also rapidly improving. Its own carbon five separation and downstream processing capabilities, and in the past not for the industry's attention to the carbon nine resources are also increasingly attracted the attention of petrochemical companies and a strong interest.

Ma Yue told reporters that in the application of carbon 5 downstream, the most industry-focused is isoprene-derived products. Among them, in 2010, with the establishment of Maoming Luhua and Qingdao Yi Kesi's two sets of isoprene rubber devices, the total production capacity of isoprene rubber in China has reached 45,000 tons, which has led to a sustained increase in the use of carbon 5 resources in China. At present, Shandong Luhua, Beijing Yanhua, Jilin Petrochemical, Panjin and Yunmeng Group and Qingdao No. 1 School both have specific plans for new isoprene rubber installations, and the domestic isoprene resource volume will be unprecedentedly tight in the future. In addition, as a carbon 5th petroleum resin, another major commodity in the downstream of Carbon Five, there are currently more than 30 major domestic production enterprises, and the total annual production capacity reaches 350,000 tons; the technology development of polydicyclopentadiene is also increasingly valued by the industry. Domestic progress has been made in this area.

Ma Yueyue also said that most of the pyrolysis carbon 9 by-product of ethylene plants in China is used as a fuel oil and carbon 9 petroleum resin, and only a small part is used to produce aromatic solvent oils or to extract other chemical products. In response to the characteristics of the cracked carbon nine fraction, Beijing Yanhua successfully produced high-quality aromatic hydrocarbon solvent oil by using two stages of hydrogenation process, thereby accelerating the industrialization of the new process of cracking carbon nine hydrogenation. Since then, Xinjiang Tianli, Liaohua, and Panjin Heyun Group have also established carbon-9 hydrogenation systems for high-quality aromatic hydrocarbon solvents, and several companies are preparing to build the devices.
