Publication Metadata only Evaluation of dispersion model performance in predicting SO2 concentrations from petroleum refinery complex(2016-01-01) Sarawut Thepanondh; Pantitcha Outapa; Suwadi Saikomol; Mahidol University; Center of Excellence on Environmental Health and Toxicology© 2015, Int. J. of GEOMATE. All rights reserved. The AERMOD and CALPUFF air dispersion models are tested for their performance in predicting ground level concentration of sulfur dioxide in Thailand. Emission data used in this study are obtained from... and 456 μg/m3 for AERMOD and CALPUFF simulations, respectively. This result indicates that CALPUFF provides more conservative of maximum result than predicted data from AERMOD. The decision to select an appropriate dispersion model in the studyPublication Metadata only Performance evaluation of AERMOD and CALPUFF air dispersion models in industrial complex area(2015-11-11) Nattawut Jittra; Nattaporn Pinthong; Sarawut Thepanondh; Mahidol University; Center of Excellence on Environmental Health© the authors. AERMOD and CALPUFF air dispersion models were evaluated for their performance in predicting nitrogen dioxide (NO2) and sulfur dioxide (SO2) in Maptaphut industrial area in Thailand. Emission data were obtained from 292 point sourcesPublication Metadata only Modeling of volatile organic compounds dispersion from open crop residue burning(2018-01-01) Duanpen Sirithian; Sarawut Thepanondh; Melanie L. Sattler; Wanna Laowagul; Mahidol University; Thammasat University; University of Texas at Arlington; Ministry of Natural Resources and Environment; Center of Excellence on Environmental Health and Toxicology (EHT)© 2018, Akademi Sains Malaysia. Burning of maize residues has been considered as a significant source of air pollution in the northern region of Thailand during the dry season. This study applied CALPUFF air dispersion model to predict ambient VOC...-April to predict 24-h average VOC concentrations and dispersions over the modeling domain of 100 × 100 km 2 with 1 km grid resolution. Four VOCs including benzene, acrylonitrile, xylene, and acetaldehyde were evaluated for different burned area scenariosPublication Metadata only Analysis of industrial source contribution to ambient air concentration using AERMOD dispersion model(2016-01-01) Laddawan Khamyingkert; Sarawut Thepanondh; Mahidol Universitydispersion model was used to simulate for the maximum 1-hr and annual average concentration within modelling domain in the year 2013. Industrial emission sources were grouped into 5 types namely 1) Gas separation plant, 2) Metal, 3) Petrochemical industry, 4Publication Metadata only Characteristics and dispersion modeling of vocs emission released from the tank farm of petroleum refinery complex(2021-01-01) Suwadi Saikomol; Sarawut Thepanondh; Wanna Laowagul; Wissawa Malakan; Jutarat Keawboonchu; Vanitchaya Kultan; Mahidol University; Center of Excellence on Environmental Health and Toxicology (EHT); Ministry of Natural Resources and EnvironmentCharacteristics and dispersion modeling of VOCs emitted from the tank farm of petroleum refinery complex were evaluated in this study. Gas phase VOCs within aboveground storage tank from all types of petroleum raw materials and products were sampled... concentration of pentane through the simulation of the AERMOD dispersion model. Predicted 1-hr average concentrations were calculated to the 5-minutes average using the concept of the peak to mean concentration with the objective to evaluate the extentPublication Metadata only NO2 and SO2dispersion modeling and relative roles of emission sources over Map Ta Phut industrial area, Thailand(2012-01-01) Chatinai Chusai; Kasemsan Manomaiphiboon; Phirun Saiyasitpanich; Sarawut Thepanondh; King Mongkuts University of Technology Thonburi; Thailand Ministry of Education; Ministry of Natural Resources and Environment; Mahidol Universityemissions from different sources or sectors (e.g., industrial, power plant, transportation, and residential) contribute to air quality degradation in the area. In this study, a dispersion study of NO 2 and SO 2 was conducted using the AERMOD model. The area... quality for the MA.Implications: Effective air quality management in Map Ta Phut Industrial Area, Thailand requires better understanding of how emissions from various sources contribute to the degradation of ambient air quality. Based on the dispersionPublication Metadata only Atmospheric dispersion of polycyclic aromatic hydrocarbons from open burning of agricultural residues in Chiang Rai, Thailand(2017-09-01) Duanpen Sirithian; Sarawut Thepanondh; Wanna Laowagul; Daisy Morknoy; Mahidol University; Center of Excellence on Environmental Health and Toxicology (EHT); Environmental Research and Training Center© 2017, Springer Science+Business Media Dordrecht.
