Abstract

The invention provides a dangerous chemical leakage pollution evaluation method. The method comprises the following steps: (1) determining a dangerous chemical dispersion source as an instantaneous leakage source or a continuous leakage source; (2) dividing the source dispersion into heavy gas dispersion and non-heavy gas dispersion of the instantaneous leakage source, and heavy gas dispersion and non-heavy gas dispersion of the continuous leakage source; (3) causing the heavy gas of the instantaneous leakage source to disperse at a concentration meeting a formula shown in the specification; (4) causing the non-heavy gas of the instantaneous leakage source to disperse at a concentration meeting a formula shown in the specification; (5) causing the heavy gas of the continuous leakage source to disperse at a concentration meeting the formula c=b0h0c0 / (bh) in the horizontal direction; (6) causing the non-heavy gas cloud of the continuous leakage source to disperse at a concentration meeting a formula shown in the specification; and (7) determining and displaying the pollution range. The method has the characteristics of accuracy, intuition and the like, is simple to use and can be widely used in the industries of chemical engineering, petrochemical, natural gas and the like.

Description

technical field

[0001] The invention relates to an evaluation method, in particular to an evaluation method for leakage pollution of hazardous chemicals. Background technique

[0002] In the chemical, petrochemical, natural gas and other industries, there are a large number of toxic and harmful hazardous chemicals. These hazardous chemicals are always in danger of leakage in all aspects of production, transportation, storage and use. Under normal circumstances, for the convenience of storage and transportation, according to the nature of hazardous chemicals, storage methods such as normal temperature pressurization and low temperature pressurization are often used. Once the hazardous chemicals leak out, they will form a cloud near the ground, which will cause serious harm to nearby people. With the development of modern industry, hazardous chemical leakage accidents occur more and more frequently, causing huge casualties and property losses, and also involving a large numbe...
