石化企业装置VOCs无组织排放测算技术研究
Research on the Measurement Technology of Unorganized VOCs Emissions from Typical Equipment in Petrochemical Enterprises
摘要
Abstract
To address the challenge of accurately quantifying volatile organic compounds(VOCs)fugitive emissions from typical process units in petrochemical enterprises,a calculation method was developed based on a mass flux model.Initially,a monitoring plane perpendicular to the prevailing wind direction was constructed downwind of the target unit to acquire multi-point monitoring data reflecting pollutant dispersion characteristics.By employing a two-dimensional Gaussian function,the area-averaged concentration of the dispersion plume across the monitoring plane was calculated and subsequently integrated with real-time meteorological data to es-tablish the emission quantification approach.Furthermore,to verify the accuracy of the proposed method,pen-tane gas release simulation experiments were conducted at a testing facility in northern China,utilizing typical petrochemical emission configurations-specifically point,surface,and bulk sources-as target release sources.Experimental results demonstrated that under conditions where the prevailing wind direction was approximately perpendicular to the monitoring plane,the average wind speed exceeded 1 m/s,and the monitoring plane suffi-ciently covered the dispersion plume,the average quantitative errors of the calculation method for the point,are-a,and volume source leakage scenarios were 6.50%,16.94%,and 13.69%,respectively.关键词
