陕西省兰炭行业SO2、NOx产排污系数核算研究

摘要

SO2 In this paper, single source detection method was used to determine the emission quantity of and NOx from three semi coke companies. The emission coefficient was calculated and compared with the corresponding coefficient in the Pollutant Emission Coefficient Handbook for Industrial Sources of the First National Pollution Source Survey (hereafter abbreviated as the Handbook ). The results showed that the emission coefficient of SO2 from semi coke industry was 0.0057 0.0733 kg/t, and that of NOx was 0.0824 0.2014 kg/t. By comparison with the data in the Handbook, it was found that the emission coefficient of“”~~SO2 from the semi coke industry in the Handbook was within the range derived in this study, but with the mean value of approximately 2.9 times of the result from the study. Moreover, the emission coefficient of NOx from the semi coke industry in the Handbook was without the range derived in this study, with the mean value of approximately 2.8 times of the result from the study.%采用单源检测法对三家兰炭企业的SO2、NOx排放量进行了测定，核算了产排污系数，并与《第一次全国污染源普查工业源产排污系数手册》（以下简称《手册》）中对应系数进行了比较。结果显示，兰炭行业SO2产排污系数为0.0057～0.0733 kg/t ， NOx产排污系数为0.0824～0.2014 kg/t ，与《手册》比较得知，焦化行业SO2产排污系数在本研究的产排污系数区间内，但均值约是本研究产排污系数的2.9倍；焦化行业NOx产排污系数与本研究中排污系数区间无重叠，且均值约是本研究产排污系数的2.8倍。
