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
