Title VOC emission rates and emission factors for a sheetfed offset printing shop
Bibliographic information Apr. 1995, Vol.56, No.4, p.368-376. Illus. 15 ref.
Abstract Emission rates of VOCs (volatile organic compounds) were determined during the production phase in a sheetfed offset printing shop. The determination made use of measured concentration data (gas chromatography), ventilation rate information and mass balance models that characterize printing space. The average VOC emission rate was 470g/hr (range 160-1100g/hr). These values were in good agreement with the amounts of VOC, hexane, toluene and aromatic hydrocarbons determined from estimated solvent usage and measured solvent compositions. Comparison of the emission rates with source activities indicated an emission factor of 30-50g VOC/press cleaning. Based on the test observations it was estimated that this typical small printing facility was likely to release 1-2t VOC/year. Because this methodology does not require the use of temporary local enclosure and does not interfere with worker activities, it might be usefully applied in other industries with extensive solvent use, such as the surface coating industry.
