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

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

4 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 INTRODUCTION  Results shown here: Interim + Subject to double checking as part of QA process (ongoing)

5 Thailand & Its regions INTRODUCTION Region No. of Power Plants % No. of Industrial Facilities a % Central , Eastern , Northern , Northeastern , Southern119.59, Source: Department of Industrial Works a) Excluding power plants

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