The "flashover" accident of the PX project in Zhangzhou has recurred
According to the China Youth Daily, China Drying Network reported that at 4:35 am on July 30th, an explosion occurred at the Gulei Petrochemical (PX Project) plant in Guleigang Economic Development Zone, Quzhou City, Fujian Province. According to the management committee of the Guleigang Economic Development Zone, there were no casualties on the scene of the accident, no major equipment damage, and no material leakage. All fire-fighting water was poured into the fire fighting pool. Air and water pollution were not found around the site. According to the report, it is understood that a hydrocracked pipeline of the PX (paraxylylene) project in Quzhou, which has not yet been put into use, was filled with hydrogen gas during test pressure, and cracking occurred in the weld cracking, resulting in partial damage to the pipeline. On July 13 this year, the pipeline has passed nitrogen pressure test and began to use hydrogen pressure test on July 18. As for the impact of the accident, the report quoted Huang Yaozhi, Chairman of Tenglong Aromatic Hydrocarbons (Yinzhou) Co., Ltd., as saying that the accident occurred was only a device for raw material transportation, and would not have much impact on the operation of the entire project. According to an official report, the explosion in the early morning caused the glass of some houses in a nearby village to shatter or break. Zhangpu County has organized personnel to enter the village to enter homes, conduct timely and comprehensive investigations on the damage of the villagers' houses, and formulate compensation plans. At present, the Ganzhou Municipal Committee and the municipal government have established an accident investigation team to investigate the causes of the flash fire. At the same time, the safety supervision and fire control departments in Ganzhou City will conduct large-scale inspections of potential safety hazards. "More events" project In fact, prior to the accident, the Guzhou project in Ganzhou was not going smoothly. According to the Daily Economic News, the 80,000-ton/year paraxylene project of Tenglong Aromatic Hydrocarbons (Quzhou) Co., Ltd. entered the Guleigang Economic Development Zone in Zhangzhou, Fujian Province. The project was originally planned to be built in the southern area of ​​Haishu, Xiamen, and was approved by the National Development and Reform Commission in February 2004. It was officially started in November 2006 and was suspended in the second half of 2007. In the first half of 2008, the Fujian Provincial Government decided to relocate the project to Gu Lei. In September of that year, the "Gu Lei Regional Development and Construction Plan" was approved by the provincial government. In March 2009, the National Development and Reform Commission formally approved the project. In addition, the First Financial Daily also quoted a person close to the project saying that although the project had reached trial production standards in June this year, it did not actually produce materials, which may cause some problems. In January of this year, as the adjustment of raw materials was not started without the environmental impact assessment, Tenglong Ganzhou Company received the administrative penalties of the Ministry of Environmental Protection. The Ministry of Environmental Protection ordered the relevant raw material adjustment project to be suspended. Before the approval of the environmental assessment, it was not allowed to resume construction without permission and a fine of 200,000 yuan was imposed. At that time, Tenglong Xinzhou Company had no objection to the penalty. The raw material adjustment project that was ordered to stop construction had little impact on the progress of the entire project, and the raw material adjustment device had already completed most of the time. Overall, construction has not been affected. However, the report also stated that the PX project involved in the project as a local key project, there is also a huge pressure to catch up. In August last year, an intermediate handover ceremony for three units of hydrocracking, hydrogen production, and pressure swing adsorption (PSA) was held, signifying that the leading device of the PX project entered the trial phase. At that time, a news report metaphorized the turbulent progress of the project: “In order to strive for the production as soon as possible, the construction unit worked overtime and seizes the project progress; the various departments of the management committee focused on the target and mission, provided extraordinary service, and continuously operated with overload. †In fact, the Tenglong Group, which is owned by Tenglong Aromatic Hydrocarbons (Quzhou) Co., Ltd., does not seem to stop there. The First Financial Daily also reported that Xianglu Petrochemical, which belongs to the same company as the Tenglong Quzhou Company and Xianglu Dragon Group, had also had environmental problems. Xianglu Petrochemical completed its production of 900,000 tons of refined terephthalic acid (PX's downstream product, or PTA) project in Haishu South Industrial Park in Xiamen in 2002. Currently, its single-line production capacity ranks first in the world. Environmentalists who have visited Xianglu Petrochemical’s PTA project stated that the project was penalized by the environmental protection authority for excessive discharge during the initial stage of construction and that the project has not yet substantially improved. “When we went to visit earlier, we also felt a very strong odor. The surrounding residents had great opinions on it.†For the accident in Quzhou Gulei, the report quoted the director of the Public Environment Research Center Ma Jun as saying that “After the accident in Zhangzhou PX, the person in charge did not express apologies but only emphasized that it had little impact on production. This again shows that Safety production has not been placed in the most important position.†Whether it is the PX project in Zhangzhou or the PTA project in Xianglu Petrochemical, the safety and environmental protection issues of the company (group) are not trustworthy. PX Project Security Controversy Resurrects The occurrence of the Gulei project accident in Zhangzhou has once again pushed the security disputes of the PX project to the focus of public opinion. The First Financial Daily reported that the safety of the PX project is in the end. Speaking of this topic, a person in charge of a large-scale PX plant who did not want to be named became bitter. The person in charge said: "Our factory has been in operation for more than 10 years and there has been no safety accident. You see that our workers' working environment and protective measures in the factory are not much different from other chemical plants. †The responsible person also stated that the PX plant owned by his company is not far from the residential area. It is a residential area after the first factory. Everyone has been safe for many years. The plant construction of the factory does not require special protective measures. Almost rarely received complaints from residents about environmental issues. “Our factories are monitored around the clock. Once there is a problem of excessive emissions, the government’s environmental protection department and neighboring residents can all know.†Cao Xianghong, an academician of the Chinese Academy of Engineering, has also been publicly known as PX. He said that the PX environmental pollution behavior is mainly reflected in drinking water and the atmosphere, and the residue and accumulation are not serious. The most serious hazard of PX is its flammability, but it is less dangerous than natural gas and liquefied petroleum gas. Only when its vapor and air form an explosive mixture, it can cause a fire and explosion in the event of an open flame or high heat. However, domestic environmentalists still have questions about the safety of the PX project. Ma Jun said that although the PX chemical product itself is not highly toxic, the most important thing is that the production process has high risks. How to strengthen the supervision of the production process is the most important. “If there is no high risk, why do safety accidents occur repeatedly? Some chemical industry people's defenses are pale before the facts.†Ma Jun said that government agencies and chemical companies should put more emphasis on the management of safety and environmental issues. Instead of rushing to argue for the industry. The People's Daily also commented that the development of the PX industry was, in the final analysis, for the people's livelihood. In the face of a growing demand gap, the development of China's PX industry is imperative. The public’s concern and concerns about the establishment of projects, environmental assessment, safety, and supervision are also worthy of great importance. The low toxicity of the products, the advanced equipment, and the tighter flow, the “human†factor are always decisive. Regulators, managers, and people who produce ... Only when everyone sticks to the bottom line of safety can they be truly credible. Paraxylene prices will rise? And behind the dispute, what impact will the accident have on the industry? Daily economic news quoted Chen Ling, an analyst at the business community, as saying that the project accounted for 7% to 8% of the domestic production capacity of paraxylene, which would be affected by the accident or would stimulate the price of the product and the industrial chain. “At present, China’s dependence on paraxylene imports has reached 46%.†Chen Ling said that according to the agency data monitoring shows that paraxylene prices continued to rise for many years, the average price in 2009 was about 8,500 yuan / ton, slightly in 2010 It fell back to 8,350 yuan/ton, but it soared to 11,850 yuan/ton in 2011 and remained at 11,350 yuan/ton in 2012. As of 2013, the average price was about 11,000 yuan/ton, and the highest price reached 12,800 yuan/year. Ton. Chen Ling said that according to the monitoring of the agency, paraxylene will be increased in August, the price increase rate of 1.04%, an increase of about 150 yuan per ton. The chemical industry analyst of another institution believes that the "flashover" accident is accidental and does not have a major impact on the project. Therefore, it should not affect the project's production plan. However, this type of project construction supervision committee will play a warning role, and the relevant construction units may increase the investment and supervision of the relevant aspects of the project, but will not affect the normal project construction progress and commissioning plan. “For chemical plants, the delay in delaying the construction period is very large. Many projects have already taken orders at the time of construction, and paraxylene is a chemical raw material with a relatively large domestic gap. Therefore, the accident will not cause major damage to the entire industry. The impact of the company's production plan and construction schedule should be carried out according to plan.†The analyst said that although it is not ruled out in the next few months, paraxylene prices will maintain a certain degree of increase, but the main reason for the rise is still It is determined by the supply and demand relationship. The report also cited the agency's monitoring data and showed that in 2012, the domestic production capacity of paraxylene was less than 9 million tons, the demand reached 13.85 million tons, and there was a gap of 30%. In this case, the price is very likely. Further rise. In addition, due to the impact of the flash fire accident, it does not rule out the psychological expectations of some people for the price rise, so under the dual factors, the paraxylene price may rise in the next few months.
