1997年，美国环保局颁布了直径小于2.5微米的颗粒物（PM2.5）的新环境空气标准。需要源排放数据来评估石油工业燃烧源对环境PM2的贡献。5种浓度。本报告介绍了每小时1.14亿英热单位（MMBtu）燃气炼油厂工艺加热器的颗粒物测量结果。使用稀释通道研究试验方法和传统EPA取样方法进行颗粒物堆积测量。

In 1997, the USEPA promulgated new ambient air standards for particulate matter smaller than 2.5 micrometers in diameter (PM2.5). Source emissions data are needed to assess the contribution of petroleum industry combustion sources to ambient PM2.5 concentrations. This report presents particulate measurement results from a 114 million British thermal unit (MMBtu) per hour gas-fired refinery process heater. The particulate stack measurements were made using both a dilution tunnel research test method and traditional EPA sampling methods.
