关于石油工业燃烧源产生的细气溶胶的排放和特性，现有数据很少，可用的有限信息也不完整和过时。美国石油学会（API）制定了一项测试方案，以解决这一数据差距，具体目的是:制定主要细颗粒物（即烟囱烟气中存在的颗粒物，包括可冷凝气溶胶）排放的排放因子和形态分布，尤其是来自燃气燃烧装置的有机气溶胶；识别和表征二次颗粒物（即通过烟囱排放物在大气中的反应形成的颗粒物）前体排放物。 本报告介绍了炼油厂催化裂化装置（FCCU）试验方案评估试点项目的结果。

There are few existing data on emissions and characteristics of fine aerosols from petroleum industry combustion sources, and the limited information that is available is incomplete and outdated. The American Petroleum Institute (API) developed a test protocol to address this data gap, specifically to:Develop emission factors and speciation profiles for emissions of primary fine particulate matter (i.e., particulate present in the stack flue gas including condensible aerosols), especially organic aerosols from gas-fired combustion devices; andIdentify and characterize secondary particulate (i.e., particulate formed via reaction of stack emissions in the atmosphere) precursor emissions.This report presents the results of a pilot project to evaluate the test protocol on a refinery fluid catalytic cracking unit (FCCU).
