1 General
In order to prevent, control and deal with sulfuric acid irrigation area of large-scale leakage of acid accidents, rapid, orderly and efficient emergency rescue work, minimize casualties, mitigate the environmental pollution accidents and reduce property damage, and quickly restore normal production, the development of this plan.
2 Emergency Planning
2.1 Basic situation
The existing company has sulfuric acid irrigation workshop two sets of acid production system annual output of 1.01 million tons of sulfuric acid, coupled with the current technical renovation project a set of acid production system annual output of 660,000 tons of sulfuric acid, the annual output of *** counting 1.67 million tons of sulfuric acid with a concentration of 98.5%, the finished product acid pumps through the finished acid transported to the finished product acid warehouse. The acid storehouse is located in the northwest corner of the old plant, about 400m away from the acid workshop of the existing project and about 700m away from the acid workshop of the technological reform project, and the surrounding area is basically an open area except for the internal railroad line (acid line) in the north of the plant.
2.2 Number and nature of hazardous sources
Sulfuric acid workshop acid storage **** there are 12 ground vertical storage tanks, in addition to the 4 # tanks can store 3000t sulfuric acid, the rest of the tanks can store 5000t, the maximum capacity of 58000t, the technical transformation project does not add new sulfuric acid storage tanks.
Sulfuric acid is a colorless and transparent oily liquid with strong corrosive property and can react with many substances. Specific gravity is 1.83(below 20℃), boiling point is 338.8℃, crystallization temperature is 1.8℃.
2.3 Possible Major Accidents and Consequences
Due to the tanks, pipes and valves are corroded by sulfuric acid all year round, there may be a large leakage of sulfuric acid, which may be lost from the factory drains and sewers to the sewage treatment reservoirs (String Ridge Reservoir), and even enter into the Xinjiang River Basin, resulting in serious pollution.
2.4 Emergency Material Analysis
The acid store tank area is surrounded by a cofferdam to block the loss of leaking acid. The instrument room of the acid store is equipped with an acid leakage alarm device; the site is equipped with a sufficient number of movable wrenches, pipe wrenches, gas masks, acid-resistant chemical-resistant suits, acid-resistant masks, acid-resistant gloves, acid-resistant rainboots, showerheads, burn medicines (Mepore, etc.), walkie-talkies, as well as calcium carbide slag used to neutralize the sulfuric acid; the general warehouse of the supply and marketing company has liquid alkali in reserve.
2.5 Emergency Measures
Once an acid leakage accident occurs, it can take measures such as pouring between the leaking tanks and other tanks, recovery of leaking acid, addition of alkali neutralization and plugging of leakage.
