CNOOC Daya Bay Exhaust Emissions Severely Exceeded

The CNOOC odor incident in Daya Bay has finally been officially confirmed.

According to the Guangdong Provincial Department of Environmental Protection, CNOOC Energy Development Co., Ltd.'s Huizhou Petrochemical Company (hereinafter referred to as “Huizhou Petrochemical”) has severely exceeded the standard for emissions of 400,000 tons/year of calcined post-coke projects in the Daya Bay Petrochemical Area. Also slightly exceeded. Nearly 10% of local residents are dissatisfied with the environmental problems in the petrochemical area.

Dual emission of carbon dioxide* exceeds double standard CNOOC Huizhou Petrochemical's 400,000 tons/year calcined coke project is located in Dayawan Petrochemical District of Huizhou City. The project uses the petroleum coke by-product of a 12 million-ton refinery project of CNOOC Ltd. for extended processing, with an annual output of 400,000 tons of calcined coke, 100 tons of steam per hour for waste heat power generation, and 75 tons of steam for the CNOOC Nanhai petrochemical refining project.

According to the original Guangdong Provincial Environmental Protection Bureau's environmental impact report of Guangdong Huanheng [2006] No. 1327 and Guangdong Environmental Protection Review [2007] No. 227, the total amount of COD discharged by the main pollutant of the project will be “chemical oxygen demand”. Controlled at 0.768 tons/year, "dioxide*" SO2 was controlled at 113.11 tons/year.

However, when the Environmental Protection Bureau of the Guangdong Provincial Environmental Protection Agency checked and accepted the environmental protection of the completed project, with an annual production of 330 days and 24 hours/day, the total amount of CO2 emitted by the project was 232.6 tons/year. More than doubled the previous requirement for approval of the project's environmental assessment (113.11 tons/year).

In addition, the Environmental Supervision Bureau of the Guangdong Provincial Environmental Protection Agency pointed out during the publicity that the waste gas emitted from this project mainly comes from the rotary kiln and ventilation system of the calcining system; in addition, there will be fugitive emissions in the process of plant ventilation, material crushing, and finished product transportation. Into the atmosphere. The measured value of individual plant boundary noise monitoring points in this project exceeded the Category 3 standard of “Environmental Noise for Industrial Enterprises at the Plant Boundary” (GB 12348-2008) at night, but it will not cause any disturbance to people.

Xia Jun, a member of the Environmental Resources and Energy Professional Committee of the All China Lawyers Association, told the reporter of the First Financial Daily that, in the event that the total discharge of pollutants exceeds the limit, the environmental protection department should request a deadline for rectification, and if it still exceeds the standard after rectification, it should deal with it. Penalties were imposed and they were even required to stop production.

Let More Public Participate in the EIA At the beginning of this month, the odor caused by the odor in the Daya Bay Petrochemical District caused local residents to panic and even fled overnight. Subsequently, the Daya Bay Environmental Protection Bureau stated that the odor originated from the CNOOC Huizhou Refinery, which was in the state of suspend production and maintenance. It was initially determined that the odor was generated during the steam purging process and the heavy oil evaporated into the air. However, at the time, CNOOC claimed that the gas did not harm the human body.

However, Shao Min, a professor at Peking University's School of Environmental Science and Engineering, believes that if there is odor, it proves that the elements contained in it are harmful to the body. It may be some substances containing *, nitrogen, and oxygen, which are harmful to the human body. It also reacts to generate some pollutants, such as ozone and particulate matter.

The above public notice of the Guangdong Environmental Protection Agency confirmed to a certain extent the existence of excessive emissions in Daya Bay Petrochemical Zone. Chang Cheng, the person in charge of the public participation of Nature Friends, told reporters that polluting companies often postpone the release of relevant information, causing the company to gradually lose credibility.

According to a survey conducted by the Guangdong Provincial Department of Environmental Protection on the local public in the Daya Bay petrochemical area in Huizhou, 89.8% of the residents were satisfied or basically satisfied with the company's environmental protection work, and 10.2% were dissatisfied with the environmental problems in the entire petrochemical area. .

In this regard, Chang Cheng said that the Guangdong Environmental Protection Agency should publish more detailed information on the scope of the survey and the reasons for selecting the survey. Otherwise, the above data is not convincing, and it is easy for the public who does not agree with the project to rebel against it. psychological. More importantly, government departments should allow the public to participate more in environmental assessment of related projects.

It is understood that the CNOOC Huizhou Branch is operating the second phase of the project. Huizhou City Party Committee Huang Yebin said in Daya Bay in September this year that it is necessary to speed up the approval of the second phase of the CNOOC Huizhou Refinery Project, vigorously develop the petrochemical midstream and downstream industries, and accelerate the progress of project construction. Huang Yebin also admits that the Daya Bay area is facing the pressure of safety production.
