估算固定来源的空气污染物对于编制排放清单、确定排放费用以及满足各种许可证和合规性的条件是必要的。本报告提供了适用于重质液体（HL）服务中炼油厂部件的修正排放系数，其基于广泛的现场测量。它还提供数据分析，以确定流中馏出物或残余碳氢化合物的类型是否会影响排放因子。

Estimating air pollutants from stationary sources is necessary for compiling emission inventories, determining emission fees, and meeting the conditions of various permits and compliances. This report provides revised emission factors applicable to refinery components in heavy liquid (HL) service, which were based on extensive field measurements. It also provides data analyses to determine whether the type of distillate or residual hydrocarbon in the stream would influence the emission factors.
