Control of Emissions from Seals and Fittings in Chemical Process Industries

摘要

The intent of this inhouse NIOSH project is to: (1) correlate the results and measurement method information pertinent to volatile organic compound (VOC) emissions from seals and fittings (as developed by the EPA studies) with the engineering design of these items, and (2) provide recommendations on the most suitable choices in each category of seals and fittings application for minimizing leaks and emissions therefrom. NIOSH did not undertake any emission measurements or chemical identification in this study primarily because of the extensive experimental testing studies conducted by the EPA contractors, including the Radian Corporation, Monsanto Research Corporation, Hydroscience, Inc. and numerous others. EPA's large-scale testing program was essential to obtain sufficient sampling to provide emission results having statistical significance over the range of experimental items tested.
