Evaluation of Developmental Industrial Hygiene Instrumentation at the University of Minnesota-Duluth Gasifier

摘要

Several types of monitors under active development for reliable and compound-specific measurement of fugitive emissions from coal gasification processes in real- or near-real-time were tested during gasifier run periods. The primary concerns were aromatic vapors, respirable aerosols from coal tar, and polynuclear aromatic (PNA) laden tars and oils on contaminated surfaces. The monitors tested include: (1) a second-derivative uv-absorption spectrometer (microcomputer controlled) for monitoring specific aromatic vapors; (2) an integrating, badge-sized passive sampler for airborne high-boiling PNA vapors; (3) a light pipe luminoscope for quantitative fluorometric examination of the skin; and (4) a portable fluormetric spotter for detecting PNA surface contamination.
