Fiona Fang, an oil refinery, is uninhabitable for several kilometers.

The refinery did not clearly stipulate that people should not live within a few kilometers.

Refinery refers to a factory that produces diesel oil, gasoline, kerosene, lubricating oil, petroleum coke, asphalt, ethylene and other products through distillation, catalysis, cracking, cracking and hydrofining of crude oil extracted from strata.

The classification of refineries can usually be divided into three types:

1, fuel refinery. Produce clean fuel, and some clean fuel refineries also produce lubricating oil;

2. Petrochemical complex refinery. Not only the petroleum products produced are mainly fuels and lubricants, but also chemical raw materials such as olefins and aromatics;

3. Chemical refinery. It mainly produces chemical raw materials, mainly olefins and aromatics.

Safety problems in oil refineries;

The centralized arrangement of heat pumps is not conducive to fire safety. The hot oil pump with medium temperature exceeding the self-ignition point can be set near the tower and container, and the upper part of the pump area can be ensured to be empty without any equipment or pipeline.

The safety valve of electric desalting tank is prone to fire, so the safety valve of electric desalting tank of new atmospheric and vacuum distillation unit should be set in oil phase to ensure closed discharge.

Shut-off valves are provided from the high-pressure separator to the low-pressure separator. Once the liquid level of the high-pressure separator changes abnormally, the control valve cannot be cut off in time, resulting in high and low pressure problems and serious explosion accidents.

The gas feeder of the heating furnace should improve the zoning measures and be equipped with fire extinguishers to ensure the safe and reliable operation of the furnace.

Law of People's Republic of China (PRC) on Environmental Protection Article 16 The competent department of environmental protection in the State Council shall, according to the national environmental quality standards and the national economic and technical conditions, formulate national pollutant discharge standards.

The people's governments of provinces, autonomous regions and municipalities directly under the Central Government may formulate local pollutant discharge standards for items not specified in the national pollutant discharge standards; For projects that have been stipulated in the national pollutant discharge standards, local pollutant discharge standards that are stricter than the national pollutant discharge standards may be formulated. Local pollutant discharge standards shall be reported to the competent department of environmental protection of the State Council for the record.
