  1. A NEW EMISSION INVENTORY OF POWER PLANTS AND INDUSTRIAL FACILITIES IN THAILAND PHAM THI BICH THAO, KASEMSAN MANOMAIPHIBOON*, and CHATCHAWAN VONGMAHADLEK Joint Graduate School of Energy and Environment (JGSEE) King Mongkut’s University of Technology Thonburi (KMUTT) Bangkok, Thailand http://www.jgsee.kmutt.ac.th *Corresponding Author: kasemsan_m@jgsee.kmutt.ac.th For Better Air Quality (BAQ) Conference Dec., 2006, Yogyakarta, Indonesia

  2. INTRODUCTION Emission Inventory • A comprehensive listing by sources of air pollutant emissions in a geographic area during a specific time period • Important and useful in air quality management, planning, as well as modeling Source: US EPA

  3. INTRODUCTION Air Quality Management Cycle Impact & Policy Assessment • Environmental Goals • Technical Feasibility • Economic Issues • Political Implications • Environmental Impacts • Human Health • Ecosystem • Economic • Environmental Strategy • Policies • Controls Emissions Atmospheric Processes Pollutant Distributions Atmosphere

  4. INTRODUCTION Scope of Work • Emissions covered: NOX, SO2, NMVOC, CO, NH3, OC, and BC • Reason: To support air quality studies of ozone and fine particulate matter for Thailand • Emission sources: • EGAT, IPP, and SPP • Onshore industrial facilities • Base year: 2004 • Domain: Entire Thailand • Results shown here: Interim + Subject to double checking as part of QA process (ongoing)

  5. INTRODUCTION Thailand & Its regions a)Excluding power plants Source: Department of Industrial Works

  6. METHODOLOGY General Approach where E: Emission rate [mass per time], EFuncontrolled: Emission factor without control technology [mass per activity unit], EFcontrolled: Emission factor with control technology [mass per activity unit], A: Activity rate [activity unit per time], and ER: Control efficiency (in percent)

  7. METHODOLOGY Emission Estimation Diagram Energy Consumption Industrial Processes Power Plants Industrial Facilities Industrial Facilities Semi Bottom-up Top-down Top-down Bottom-up InstalledCapacity Industrial Production SPP EGAT IPP Fuel Consumption Fuel consumption (Source Specific) Uncontrolled EFs Uncontrolled EFs Uncontrolled EFs Controlled EFs Annual Emission Estimates

  8. METHODOLOGY Emission Factors • Cao et al (2006) Inventory of black carbon and organic carbon emissions from China. • Atmospheric Environment 40, 6516-6527

  9. METHODOLOGY Assumptions • Emission control in EGAT and IPP: • Low-NOX burner and water injection • No emission control for CO & NMVOC • No emission control in SPP & industrial facilities • Average operation of industrial facilities: • 48 hours/week

  10. METHODOLOGY Energy Consumption by TSICa (in percent) a)Thai Standard Industrial Classification Source: Department of Alternative Energy Development and Efficiency

  11. RESULTS Emission Estimates for Thermal Power Plants by Region

  13. RESULTS Emission Estimates for Industrial Facilities by Region - Energy Consumption

  14. RESULTS

  15. RESULTS Emission Estimates for Industrial Facilities by TSIC - Energy Consumption

  16. RESULTS

  17. RESULTS Emission Estimates for Industrial Facilities by TSIC - Industrial Processes

  18. RESULTS Comparison to Past Emission Inventories

  19. Ongoing Work • Development of temporal distribution profiles of emission sources • Spatial allocation • Physical characterization of emission sources (e.g., stack parameters and locations)

  20. Acknowledgments • Suthisa Sanguantrakool (Department of Alternative Energy Development and Efficiency) • Piyavadee Limvoranusorn (Pollution Control Department) • Dr. Sirakarn Leungsakul (Department of Industrial Works) • Dr. Decha Pimpisut (Department of Industrial Works) • Assoc. Prof. Dr. Prungchan Wongwises (JGSEE) • Electricity Generating Authority of Thailand (EGAT) • Joint Graduate School of Energy and Environment (JGSEE).
