Impact of the ambient air quality due to the dispersion of non-methane organic compounds from Barka Landfill

Abstract

This study used the CALPUFF modeling system to study the impact of an area's geophysical and meteorological conditions on the dispersion of nonmethane organic compounds (NMOCs) into the atmosphere from the 17-year-old Barka Landfill. Barka Landfill is located in Barka, Batinah, in the north of the Sultanate of Oman. It receives waste from nearby regions such as Nakhal, Seeb, and Wadi Al-Maawel, affecting the town of Barka with landfill gas (LFG) pollution. The present study was conducted to evaluate the impact of the air dispersion of one group of NMOC gases on Barka and the region around it. The top five values of the concentrations with different average time periods, namely 1, 3 and 23 h, were compared with the allowable emission rate defined by the US Environmental Protection Agency (EPA). The results demonstrated that the present integrated modeling system (consisting of a 3D diagnostic CALMET model and Lagrangian puff dispersion CALPUFF model) could be utilized as a useful tool for evaluating the top five peak values of the NMOC emissions of the different time periods.

Trace gas emissions from municipal solid waste landfills: A review

“…After being generated inside the waste body, trace gases can go through various processes before they are collected or emitted into the environment. Important processes include diffusion (driven by concentration differences), advection (driven by pressure differences), dilution, volatilisation, adsorption, conversion and degradation, depending on the physiochemical properties of the individual trace gas (Abdul-Wahab et al, 2016;Reinhart, 1993).

“…This method is simple and has been widely used in providing trace gas emission rates for dispersion models with the purpose of assessing environmental impacts and health risks (e.g. Tagaris et al, 2003;Paraskaki and Lazaridis, 2005;Pagé et al, 2007;Moolla et al, 2013;Cai et al, 2015;Abdul-Wahab et al, 2016;Araiza-Aguilar and Rojas-Valencia, 2018). In the cited papers, emission rates of target odorous or toxic trace compounds were calculated by using various LFG production models and applying Equation (4).…”

Impact of Meteorological Parameters on Dispersion Modeling of Sulfur Dioxide from Gas Flares (Case Study: Sirri Island)

“…One of the most commonly used models by regulatory agencies in this area is CALPUFF. The performance of the CALPUFF modeling system has been evaluated in several studies [6,7,8,9,10]. Modeling the dispersion of air pollutants emitted from gas flares in locations like those that Islands require considering additional factors such as complex meteorological and terrain parameters.…”

Kinetic study of the regeneration of spent caustic via the genetic algorithm method

“…Chemical industries are among those fields which create various kinds of organic and inorganic waste in varying concentrations that must be treated. The contamination of these wastes is not only limited to water, air, soil and noise, but also has extended to the human's life (1,2). The petrochemical plants are among those industries that generate all kinds of wastewater.…”
