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

scope of work

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)

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

Ongoing Work

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