AN INTRODUCTION TO SOURCE SAMPLING - LEVEGO
AN INTRODUCTION TO. SOURCE SAMPLING . Presented by Gerald Woollatt LEVEGO . Stationary SOURCE Emission Measurement Specialists Particulate Matter vs. Gaseous Emissions SOURCE emissions classified broadly into Isokinetic SAMPLING for particulate matter and non-isokinetic SAMPLING for gaseous emissions When do we need to sample? Emission Data can be used: Government To provide data for determining appropriate emission limits. To provide data for determining compliance. To provide data for health risk assessments. To provide data for dispersion modeling. (continued). Emission Data can be used: Industry To evaluate air pollution control equipment. To provide information for design of new process and control equipment. To provide information on process operations. Isokinetic Measurement of SOURCE Emissions: Particulate emissions from a SOURCE are sampled isokinetically using a recognized international standard such as US EPA.
Theoretical Example Stack Monitoring –2 m diameter –According to ISO 9096 - Two sample ports and twelve points with a minimum sampling time of three minutes per point –Time required – minimum 36 minutes per test excl. travel, pre-test preparation, set up –Minimum of three tests required –Additional analyses could result in an increase in test
