Southern Weekend: petrochemical enterprises "Besieged" Dalian successive nightmares

if it were not for the reminder of this year's "July 16" fire, people might forget today's "July 16" oil pipeline explosion in 2010. What did the explosion that shocked the whole country a year ago leave behind for this city and the people living in it

on July 16, 2011, the oil pipeline explosion and fire fighting scene in PetroChina Dalian Free Trade Zone. (cfp/Figure)

is it "7.16", or PetroChina, or Dalian. At about 14:20 on July 16, 2011, a fire broke out in the plant area of PetroChina Dalian Petrochemical Company

at 18:10 on this day of 2010, the oil pipeline in PetroChina Dalian Free Trade Zone exploded and caught fire, causing 1500 tons of crude oil to enter the sea, making it the largest offshore oil spill accident in China

the root cause of the Dalian fire needs further investigation, and the accident in 2010 has not yet reached a final investigation conclusion. An official of Dalian municipal government said that because the central investigation team has not reached a conclusion so far, it is impossible to investigate the relevant people

On the evening of July 16, you a Ying, who lives in Dalian, said on Sina Weibo that Dalian used to be my pride, but now this feeling is getting weaker and weaker

a few hours ago, she called her close friend to verify the fire situation, because her close friend's husband was a firefighter. Sure enough, her close friend's husband was summoned back to the team at about 14:30. When he left, he just said "something serious has happened."

the plant area of PetroChina Dalian Petrochemical Company where the fire broke out is located in the northeast of Dalian, and there are many large enterprises nearby. The densely populated area in Ganjingzi District of Dalian is less than 3 kilometers away from the accident site. Villagers near the plant disclosed to the media that similar accidents had occurred in the plant in 2008, but there was no media report

5 hours later, the fire was put out. According to firefighters, a section chief of PetroChina Dalian Petrochemical Company was killed in the fire, and a young firefighter died on July 16, 2010

the fire that broke out in Dalian Dagushan Xingang Wharf in 2010 was basically extinguished after more than 2380 fire officers and soldiers and l extruder enterprises' orders would be significantly increased and 5 hours of hard work

afterwards, Miao Guodian, senior engineer of Liaoning Fire Corps, and Li Hongqi, chief of staff of Liaoning Fire Corps, posted an article in the Journal of the Armed Police College, saying that this was a rare small fire that could not be made by the tonnage of a large chemical single electro-hydraulic servo experimental machine. The land fire area was more than 60000 square meters, the wharf sea fire area was more than 10000 square meters, and the flame was as high as tens of meters

what is more serious is that the tank farm of Xingang wharf also has crude oil, refined oil storage tanks, dangerous chemicals, etc. Once these dangerous chemicals explode and burn, it will threaten the safety of the whole Dalian

in the eyes of outsiders, Dalian is a desirable tourist destination with romantic beaches and swimming pools, but Dalian is also a heavy chemical base. In the 1990s, Dalian tried to build "northern Hong Kong", vigorously improve the urban environment and introduce the financial service industry, but it revived the heavy chemical industry around 2004. During the 12th Five Year Plan period, the heavy chemical industry remained the focus of Dalian's development

at present, Dalian is an important national oil strategic reserve base and commercial reservoir in China. There are dense oil pipelines on the surface and underground, and hundreds of petrochemical plants are located near the reservoir area

fires and explosions have occurred one after another in such a high-risk place, testing the people of Dalian again and again. Following the "July 16" accident in 2010, on October 24, the oil storage tank that had been on fire again caught fire. At 6 p.m. on December 15, Dalian Xingang xinwan hotel caught fire, killing three people. This hotel is about 30 meters away from the PetroChina oil storage tank farm

an unnamed professor from the Department of environmental science and engineering, School of chemical engineering, Dalian University of technology, said that there are also practices of centralized layout of petrochemical enterprises in the world, but too much concentration will lead to environmental capacity problems. The centralized chemical enterprises around Dalian certainly pose a threat to the urban safety of Dalian, but what is the accident probability? "Flying is also dangerous, but we can't stop flying because it's dangerous. We need to use engineering to reduce the probability of accidents. At the same time, government information should be made public."

after the "July 16" accident in 2010, the Dalian municipal government re demonstrated and adjusted the layout of chemical enterprises in the city to strengthen prevention. In Changxing Island, an emerging chemical industry base, planning adjustments are sometimes made once a few days

dangerous seafood

but it is more difficult to disclose information because of the interests of all parties involved, which leads to a variety of folk speculation

on June 29th, 2011, the peninsula Morning Post reported that in ten days, three people in Dalian were poisoned by eating hemp thread, resulting in a year-on-year increase of 43.65% One dead, one injured, one critically ill. Dongzhiyang, director of the Department of critical medicine of Dalian Friendship Hospital, said that these hemp lines may have been contaminated by some kind of toxin. He speculated that it is the season for puffer fish to lay eggs, and it is likely that puffer fish eggs are attached to the hemp line

hemp thread, scientific name xuanzao, is of high edible and health value. It is born on rocks or stone marshes in the mid tidal zone, and also grows on stone marshes in the high tide zone and reefs in the low tide zone

there is a shellfish purification plant in "Zhangzi Island" of the fishery group, which is also in Jinshi beach with serious pollution. From the accident to June 2011, "Zhangzi Island" stopped the production and processing of seawater nearby, but transported water from safe areas for production. The cost of each water transportation is 11200 yuan, at least twice a day

Wang Yun, director of the company's standards and quality center, said that the previous test results of the government and enterprises showed that the water quality reached class II and class III water quality standards, but the company's production requirements were class I water quality standards

another research institution found that the seedlings were also affected through the study of a Haizhen variety seedling reserve. "Zhangzi Island" also stopped cooperating with seedling breeding plants in the polluted area after the accident, and has not been restored so far

oil eliminator "sequelae"

on June 30, 2011, on the dock of the workboat in PetroChina Dalian Free Trade Zone, we saw that the staff of PetroChina offshore emergency team were washing the oil stains on the bank wall with a 130 degree high-temperature water gun, which may be the only oil stains left by the 2010 accident to date

since June 4, 2011, Dalian environmental protection volunteer association has organized volunteers to clean up and investigate the polluted coastline every weekend, and no oil pollution has been found

however, this does not mean that the impact of the accident in 2010 has been completely eliminated. The way to clean up the pollution in 2010 is to launch the crowd tactics to recover the spilled oil; The oil film in the middle and late stage, as well as the pollution of beaches and reefs, are removed with oil eliminators

Guan Yongyi and Han Junsong, staff members of Liaoning Maritime Safety Administration, said when reflecting on the marine decontamination action of the "July 16" accident that this decontamination action exposed that China's oil spill decontamination technology was relatively backward, especially in the middle and late stage of the decontamination action, for the thin oil film, the method of spraying oil dispersant could only be used to disperse, and the effect was not ideal

the side effects of oil eliminators are obvious. When they react with crude oil, they form small particles and sink into the sea floor. In the sea floor without microorganisms and oxygen, they are difficult to degrade, and then affect the human body through seafood

the president of a research institute in Dalian said that the oil eliminators are divided into the first generation and the second generation, but in China, they are basically the first generation, and their secondary pollution is more serious. As for the actual dosage of this oil remover, it is unknown

"the hydrocarbon components in oil are soaked in seawater for a long time, and new compounds are produced after emulsification, and the degradation rate of hydrocarbon components is quite slow. Therefore, oil pollution will continue for many years." Zhao Zhangyuan, an expert in offshore environmental research in China, said, "there are many kinds of hydrocarbons, some of which can cause cancer, such as polycyclic aromatic hydrocarbons." In 2010, Zhao Zhangyuan said in an interview that the impact of the oil spill on the ecosystem will last for more than 10 years

worse, the ecological restoration after the use of oil dispersants is more difficult. There are four internationally accepted methods: covering the seabed with sand; Inject oxidant into the seabed to degrade it; Salvage the sea mud for disposal; Use biological agents that are harmless to the environment and degrade them

Dalian municipal government is also aware of the secondary pollution caused by the use of oil dispersants. According to the person in charge of an eco-environmental technology company, several companies are doing research on ecological restoration, but the Dalian municipal government does not immediately give financial support. "Only if your biological agent's decontamination effect is stronger than nature's self purification ability, the Dalian municipal government will pay research funds. As for whether to carry out ecological restoration in the future, whether to adopt these methods, and which one to adopt, it is unknown"

fuzzy compensation

the compensation amount of PetroChina is the key factor in whether to carry out ecological restoration in the future. But the official has not yet released this data

previously, unconfirmed news obtained by the media through their respective channels was that PetroChina compensated 500million yuan and officially launched the 20million ton oil refining project and the million ton ethylene project on Changxing Island. After the 20million ton oil refining project is launched, its output value is expected to account for 1/3 of Dalian's GDP. However, the subsequent compensation work of the accident will be undertaken by the Dalian municipal government

according to the minutes of the 40th mayor's office meeting held by the Dalian Municipal People's Government on March 21, the relevant district government (Management Committee) is the main body of fishery compensation work

the meeting required that the total compensation for fishery losses should not exceed 876.1055 million yuan. The compensation funds of Jinzhou new area and Ganjingzi District are shared by the city and the district. Among them, the compensation funds of Jinzhou new area are borne by the municipal finance 50%, the district finance 50%, the compensation funds of Ganjingzi District 40%, and the district finance 60%. All the funds needed for Zhongshan District, Lushunkou District, high-tech park and bonded zone shall be provided by each district, and the compensation funds for the southern waters of other urban areas shall be borne by the municipal finance

however, an official of the Dalian municipal government said that the compensation fund could not be paid by the local finance, but must be borne by PetroChina

the compensation details of PetroChina and Dalian municipal government have not been announced, and the compensation for fisheries has not yet ended

the fishery compensation scheme has been adjusted several times. Shaodeshan, director of HEZUI village, Jinsha beach, Dalian, said that the latest compensation plan was agreed by most fishermen, and only those who engaged in "bottom insertion" (the underwater aquaculture method of seafood) were dissatisfied, because the difference between the compensation amount and the actual loss was too large

"bottom inserted" aquaculture are perennial seafood, such as abalone growth cycle of 6 years, sea cucumber, sea urchin 5 years, Xia Yibei 4 years and so on. In HEZUI village, sea cucumber is the most cultivated, accounting for 80% of the total output value. Therefore, the loss is cyclical. But the compensation only covers the loss of one year

in the early morning of July 4, an aquatic company came to buy sea urchins, and the farmer Li Yasong went to the sea to fish, but because he was too thin, the Aquatic company gave up the purchase. He speculated that the reason why sea urchins are thinner may be that the food chain of marine organisms was broken due to the oil spill. July and August every year is the algae breeding period, they have to adhere to the reef to reproduce, but the oil spill event led to the algae harvest almost disappeared that year. In normal years, the income of picking wild algae in HEZUI village can reach twoorthree million yuan

in normal years, the annual output value of Li Yasong's farm reached 20 to 30 million yuan, but in 2010 it was only 5 million yuan, which was only enough for seedlings and labor costs
