VOC control techniques
VOC and odour control storage
5.4 Odour may arise from the receipt, handling and storage of organic solvents and
organic solvent containing liquids. Careful siting of storage and mixing tanks,
particularly in relation to new and replacement tanks, and controlled handling of
odorous liquids may help prevent offensive emissions off-site. In addition:
‣ All potentially odorous waste materials should be stored in suitable closed
containers or bulk storage vessels, where appropriate vented to suitable
abatement plant.
VOC control handling
5.5 The receipt, handling, use and storage of organic solvents and organic solvent
containing liquids will give rise to fugitive releases of VOC.
‣ Coatings containing VOC should be stored in closed storage containers.
Spraybooths
5.6 All paint spraying operations should be carried out in a totally enclosed booth under
negative pressure so as to prevent fugitive emissions of odour and particulate
matter.
5.7 Spraybooths should be designed to meet the emission limit for particulate matter in
Table 4.1. Regulators should be provided with a guarantee from the spraybooth
constructor that a newly-installed booth will meet this emission concentration limit,
and the guarantee should be supported by emission test data for the spraybooth
type to which the guarantee relates. Where an existing spraybooth is upgraded to
achieve the above emission concentration limit in respect of particulate matter, a
guarantee should be obtained either from the spraybooth constructor, or the
company which carries out the upgrading, that the upgraded booth will meet the
emission concentration limit. The guarantee should be supported by emission test
data for the spraybooth type, fitted with the filtration system, to which the guarantee
relates.
5.8 Spraybooths should be serviced and maintained in accordance with the
manufacturers‟ recommendations so as to maintain the validity of the guarantee of
emission concentration limit.
