The explosion accident of the Shuanghua Plant of Jilin Chemical Industry Co., Ltd. caused widespread concern. The preliminary identification of the cause of the accident was caused by the device's clogging.

At about 1:45 pm on November 13th, a nitromation unit of the aniline plant of the Shuanghua Plant of Jilin Petrochemical Company caught fire. Central leaders such as Wen Jiabao expressed great concern about the accident.
It is understood that the initial cause of the accident was identified as: P-102 tower blockage, poor circulation, due to improper handling, an explosion.
After the accident, the local government organized more than 10,000 residents to be evacuated. Wang Yunkun, Secretary of the Jilin Provincial Party Committee, instructed to monitor air pollution, do a good job of evacuation and evacuation, and ensure the safety of other chemical installations around. At the same time, we must carefully investigate the causes of the accident, and we must learn lessons from it.
The then-provincial governor Wang Hao conveyed the instructions of the central leaders Wen Jiabao, Huang Ju, and Hua Jianmin: To prevent the accident from expanding, to find out the cause of the accident; search and rescue work should be closely monitored to prevent toxic gases in the site from exceeding the standards and secondary accidents. Efforts should be made to evacuate the residents at all times to ensure the stability of residents' lives.
On the day, the fire was effectively controlled. The five sets of equipment of the Shuangben Factory are all parked. The pipeline connected to the accident device and the connected devices have all been cut off to complete the safe isolation. As of the time of the press release, 6 people were still missing. Two seriously injured people are not at risk. More than 20 people with minor injuries are being observed in hospital.
It is understood that the annual output of aniline produced by Jilin Petrochemical Company is 136,000 tons. The device that was exploded this time was the new expansion device that was put into operation in August 2003, with an annual production capacity of 70,000 tons. Relatively speaking, this aniline device is relatively independent, and this accident will not have much impact on the production of another device and other devices. So far, the other branches of Kyrgyzstan production is normal.
The reporter learned from related parties that on November 14th, Wang Lilin, member of the Party Group, deputy general manager and safety director of China National Petroleum Corporation, went to the scene of the accident to direct the rescue. General Manager of Sinopec Jilin Petrochemical Company Yu Li made a five-point report: one is to do everything possible to prevent secondary accidents; the other is to strengthen the real-time monitoring of the atmosphere and water bodies. At present, the scene of accidents and surrounding air are qualified, and there is no change in water bodies. Third, they are fully looking for people whose whereabouts are unknown. Fourth, they actively cooperate with provincial, city, and PetroChina accident investigation teams to carry out their work. Fifth, they are timely and accurate in information release work to prevent false information. Spread.
It is understood that after the “11·13” explosion accident, Jilin Petrochemical quickly initiated an emergency plan to monitor the air quality in the installation and residential areas in real time. The medical staff of the hospital and the hospital of Jilin Employees Hospital spare no effort to transport and rescue more than 20 wounded people. Forty-five or fifty fire engines and dozens of ambulances are all night vigils. Local staff and citizens, as well as some restaurants, volunteered to deliver meals and volunteer blood donations.
At present, Jilin Petrochemical employees have carried out extensive production and self-help activities. Jilin Petrochemical Company’s chemical machinery factory and packaging plant were among the affected units in the explosion. They seized and repaired the damaged glass to ensure normal production.
News link aniline is an important organic chemical raw material and chemical product. There are more than 300 kinds of chemical products and intermediates obtained from it. It has the following advantages in dyes, medicines, pesticides, explosives, spices, rubber vulcanization accelerators and other industries. Extensive application, development and utilization of the prospects are very broad. At present, aniline is produced by the catalytic hydrogenation of nitrobenzene, that is, benzene is produced by nitrating nitrobenzene, and nitrobenzene is hydrogenated to make aniline.
The nitration process of benzene is a violent exothermic reaction. Excessive temperatures can exacerbate the reaction rate and form a vicious cycle. Therefore, it is said that the nitrification system is prone to explosion. The nitrification unit produces explosions that produce smoke and produce incomplete combustion, such as hydrocarbons, nitrogen oxides, etc. Hydrogen is dangerous when hydrogenation is used to produce aniline, but now it is controlled by computers. Once hydrogen leaks, Will be discovered in time, generally no accidents.
