Regulatory Measures against Air Pollutants Emitted from Factories and Business Sites and the Outline of Regulation - Specific substance emission facilities and designated substance control standard for benzene
Specific substance emission facilities and designated substance control standard for benzene
Designated substance emission facilities (designated by government ordinance) | Outline of designated substance restriction standard (set by official notification) | |
---|---|---|
1 | Drying facilities to evaporate benzene (limited here and in subsequent sections to solutions in which volumetric percentage of benzene concentration is at least 60 %) and the hourly draft fan capacity of which is at least 1,000 cubic meters. | Limited to facilities designed to evaporate benzene used in solvents.
|
2 | Coke oven that processes raw materials at a daily rate of at least 20 tons. | Applied to gas emitted from the coal loading port and also from the discharge port of the dust collector on the coal-loading vehicle.
|
3 | Distillation facility for recycling benzene (excluding the topping plant) | Limited to facilities designed to recycle benzene used as solvent
|
4 | A dealkylation facility used to manufacture benzene (excluding sealed type) | Excluding facilities incorporating the flare stack in the process
|
5 | A storage tank of benzene with a capacity of at least 500 kiloliters | Excluding tanks with a floating roof. Also, the criteria apply to gas emitted when benzene is in the tank.
|
6 | A reaction facility which uses benzene as a raw material and which processes benzene at an hourly rate of at least 1 ton (excluding sealed type). | Excluding facilities incorporating the flare stack in the process
