Description of the drawings
Fig. 1 is the flow chart of the dangerous scenery identification implementation method preferred embodiment that LNG storage tank of the present invention is revealed.
Specific embodiment
The present invention provides the dangerous scenery identification implementation method that a kind of LNG storage tank is revealed, to make the purpose of the present invention, technology
Scheme and effect are clearer, clear and definite, and the present invention is described in more detail below.It should be appreciated that described herein concrete
Embodiment only to explain the present invention, is not intended to limit the present invention.
As shown in figure 1, the stream of the dangerous scenery identification implementation method preferred embodiment revealed for LNG storage tank of the present invention
Cheng Tu, the method comprising the steps of：
Step S100, the accident possibility occurrence value for pre-setting LNG storage tank leakage, consequence severity value, according to accident
The product of possibility occurrence value and consequence severity value determines risk Metrics, and correspondence obtains included multiple in risk Metrics
The corresponding risk class of product；
Step S200, the accident possibility occurrence actual value for obtaining LNG storage tank leakage, and consequence seriousness actual value, and
The product of acquisition accident possibility occurrence actual value and consequence seriousness actual value；
Step S300, the product that accident possibility occurrence actual value and consequence seriousness actual value are obtained according to risk Metrics
Corresponding practical risk grade.
In embodiments of the invention, the result of dangerous scenery identification is that the high scene of risk is filtered out, therefore concrete real
Shi Shi, the accident possibility occurrence value include 5 grades, are designated as few plague grade, possible plague grade respectively, are likely to
Plague grade, the grade that happens occasionally and the normal plague grades of Jing；Wherein, few plague grade correspondence accident possibility occurrence value is 1,
Possible plague grade correspondence accident possibility occurrence value is 2, it is likely that plague grade correspondence accident possibility occurrence value is 3, when
It is 5 to have plague grade correspondence accident possibility occurrence value for the normal plague grade correspondence accident possibility occurrence values of 4, Jing.
Wherein, when accident possibility occurrence value is 1, expression is unlikely to occur；When accident possibility occurrence value is 2, table
Show；When accident possibility occurrence value is 3, represent during whole operation
Repeatedly may occur；When accident possibility occurrence value is 4, represents and often at least occur every year once or during whole operation
There is generation (more than once)；When accident possibility occurrence value is 5, represents 1 year and occur repeatedly.
The consequence severity value includes 5 grades, is designated as small grade, less grade, larger grade, great etc. respectively
Level and calamitous grade；Wherein, the corresponding consequence severity value of small grade is 1, the corresponding consequence severity value of less grade
For 2, the corresponding consequence severity value of larger grade is 3, and the corresponding consequence severity value of great grade is 4, calamitous grade pair
The consequence severity value answered is 5.
Wherein, the concrete statistical form of consequence severity value such as table 1：
Table 1
The risk Metrics are 5 × 5 matrix.In risk Metrics in included multiple products, when product is less than or waits
When 3, corresponding risk class is 1, and when product is more than 3 and is less than or equal to 8, corresponding risk class is 2, when product is more than 8
And corresponding risk class is 3 during less than or equal to 14, when product is more than 14 and is less than or equal to 19, corresponding risk class is 4,
When product is more than 19 and is less than or equal to 25, corresponding risk class is 5.
Specifically, the concrete statistical form of the risk Metrics such as table 2：
Table 2
It can be seen that, in the present invention, LNG storage tank is revealed possible dangerous scenery identification and uses HAZID analytic approach.HAZID
(Hazard Identifications) be using the current generation existing data relevant with technological process and total figure arrangement, from
The aspect identification main hazard source such as environment and external action, the outer facility of within battery limit, the main purpose of its HAZID analysis are mainly known
Other battery limit (BL) scope inside/outside essential dangerous matter sources that may be present, high-grade, assess the risk class of picked out dangerous matter sources,
And cut down risk possible approaches, and determine need to carry out the key device of quantitative risk analysis (quantitative analysis).
In sum, the dangerous scenery identification implementation method that LNG storage tank provided by the present invention is revealed, method include：In advance
Accident possibility occurrence value, consequence severity value that LNG storage tank is revealed first are set, it is tight according to accident possibility occurrence value and consequence
The product of principal characteristic value determines risk Metrics, and correspondence obtains the included corresponding risk class of multiple products in risk Metrics；
