To share my EH&S experiences on a large scale project.
When its all said and done:
Vacuum Tower Bottoms/Asphalt
3. Involvement with on site safety/prevention program and construction
Marsulex (Sulphur Plant)
Vapour recovery project for ship loading will reduce benzene emissions
There are emission factors related to all coke handling sources.
Credit for controlling emissions is taken.
Final emission releases are calculated and then placed in a
dispersion model to determine impact to the community
Draft Air Quality Regulation stipulates 24 hr average of 30 ug/M3
Results from new coker unit and existing plant indicate 1.8 ug/M3
However background of City at closest air monitoring stations is 32 ug/M3
Significant schedule delays if coker foundation work is not started this year
Live butane spheres
Current berm around spheres needs to be removed and recontoured
Then rock removal 3-4’
Then build barrier wall
Then start foundation work
It would appear that this is a significant risk but how much?
We engaged Ertugral Alp-risk consultantCoker Foundation Work Close to Butane Spheres
