摘　　要：以江苏省为例,针对化工企业装置泄漏检测与修复(LDAR)逸散量和挥发性有机物(VOCs)排放总量定量分析,提出了一种核定典型化工行业LDAR逸散量占比的方法。结果表明:以间歇性生产为特点的有机化工类企业和以连续化生产为特点的石化类企业LDAR逸散量和VOCs排放总量均呈下降趋势;石化类企业LDAR逸散量占比呈下降趋势,有机化工类企业LDAR逸散量占比呈上升趋势;石化类企业LDAR逸散量占比远大于有机化工类企业,是无组织排放管控的重点;有机化工类企业LDAR逸散量占比虽然低,但对VOCs排放的贡献逐渐提高。A method for verifying the proportion of Leak Detection and Repair(LDAR)emissions in typical chemical industry was established based on the quantitative analysis of LDAR emissions and Volatile Organic Compounds(VOCs)emissions.Results showed that the LDAR emissions and VOCs emissions showed downtrend both in organic chemical enterprise with intermittent production and petrochemical enterprise with continuous production.The proportion of LDAR emissions was in downward trend in petrochemical enterprise,while in organic chemical enterprise,it was in upward trend.The proportion of LDAR emissions in petrochemical enterprise was far more than that in organic chemical enterprise,indicating that unorganized emission was the key pollution source of management and control.Though the proportion of LDAR emissions in organic chemical enterprise was low,its contribution to VOCs emissions was gradually increasing.
