4) VOCs Emission amount calculation
According to the pollution sources VOCs property material that step 3) determines, total VOCs concentration is acquired according to the following formula:
C in formulajThe mean concentration of path VOCs property material is monitored for the odd-numbered day,For odd-numbered day VOCs property material Zhan total VOCs's
Average percent, CiFor odd-numbered day total VOCs concentration；
It is poor that the total VOCs concentration of the total VOCs concentration and background dot being calculated with monitoring point is made, with the highest difference in monitoring in seven days
As uncontrollable discharge source VOCs concentration, calculated using safety and sanitation protection distance inverting formula:
In formula: Cm--- the uncontrollable discharge source VOCs maximum concentration calculated in monitoring in seven days, mg/m3；
X --- monitoring point is apart from emission source frontier distance, m；
Production unit area S, m where S --- uncontrollable discharge source2；
A, B, C, D --- design factor, zero dimension, the pollution sources from nearly five annual mean wind speed in enterprise location and monitoring result
It looks into and takes in category table；
Qc --- VOCs discharge amount, kg/h.

Step 1) the monitoring method are as follows: using the infrared wind direction under uncontrollable discharge source of open type apart from emission source boundary 2m with peripheral hardware
Set monitoring route, the one group of data collection and analysis of completion in every 2 minutes, continuous sampling in daily 4 hours or more, continuous monitoring seven days.
3. petrochemical enterprise uncontrollable discharge source VOCs discharges method for measuring and calculating according to claim 1, it is characterised in that
Each data sampling period residence time is 10~60 seconds in step 2).
4. petrochemical enterprise uncontrollable discharge source VOCs discharges method for measuring and calculating according to claim 1, it is characterised in that
Step 3) the VOCs characteristic contamination determination method are as follows: the concentration coefficient of variation and weight gain product reckling, knot
It closes THE PRINCIPAL FACTOR ANALYSIS method and extracts the mode that the factor of feature > 1 combines.
5. petrochemical enterprise uncontrollable discharge source VOCs discharges method for measuring and calculating according to claim 1, it is characterised in that
It includes benzene, meta-xylene, ortho-xylene, paraxylene, styrene, second that open type infrared gas analyser, which monitors substance classes,
Alkane, propane, butane, butylene, propylene.
6. petrochemical enterprise uncontrollable discharge source VOCs discharges method for measuring and calculating according to claim 1, it is characterised in that
In step 4), according to total VOCs density calculating method, total VOCs concentration of seven days monitoring points and background dot is acquired respectively.
7. petrochemical enterprise uncontrollable discharge source VOCs discharges method for measuring and calculating according to claim 1, it is characterised in that
