در این مقاله فاکتور انتشار (NOx،CO2 و SO2) خروجی از نیروگاه های کشور ارائه شده است. فاکتور انتشار گازهای حاصل از احتراق برای 50 نیروگاه بخار، گازی و سیکل ترکیبی با ظرفیت 34863 مگاوات بر اساس مشخصات بهره برداری نیروگاه مشتمل بر ظرفیت تولید، نوع و میزان سوخت مصرفی و تغییرات آن، مشخصات دودکش، آنالیز گازهای حاصل از احتراق و مشخصات فیزیکی گاز دودکش بر حسب g/kWh محاسبه شده و با میانگین گیری وزنی بر...
Direct emissions of air pollutants from the cement industry in China were estimated by developing a technology-based methodology using information on the proportion of cement produced from different types of kilns and the emission standards for the Chinese cement industry. Historical emissions of sulfur dioxide (SO2), nitrogen oxides (NOX), carbon monoxide (CO), particulate matter (PM) and carb...
The high-order decoupled direct method in three dimensions for particulate matter (HDDM-3D/PM) has been implemented in the Community Multiscale Air Quality (CMAQ) model to enable advanced sensitivity analysis. The major effort of this work is to develop highorder DDM sensitivity analysis of ISORROPIA, the inorganic aerosol module of CMAQ. A case-specific approach has been applied, and the sensi...
Abstract This work constructed a divided diaphragm seawater electrolysis system with two tandem packed towers for the synergistic removal of NOx and SO2. The first tower was mainly used to oxidize NO SO2 by AC (active chlorine), second further absorb NOx. factors affecting on removal, including ACC chlorine concentration), pH value, initial concentration temperature in oxidation were investigat...
The dry treatment of flue gas produced by incineration processes is discussed thermodynamically. The study investigates the theoretical limits achieved by sodium and calcium based sorbents in the removal of the pollutant species HCl, NOx and SO2. Calculations were performed varying the temperature and the molar ratio between the amount of the injected alkaline sorbent and the content of the pol...
Emissions from 15 agricultural fires in the southeastern U.S. were measured from the NASA DC-8 research aircraft during the summer 2013 Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEACRS) campaign. This study reports a detailed set of emission factors (EFs) for 25 trace gases and 6 fine particle species. The chemical evolution of the primar...
Plug-in hybrid electric vehicles (PHEVs) have been promoted as a potential technology to reduce emissions of greenhouse gases and other pollutants by using electricity instead of petroleum, and byimproving electric system efficiency by providing vehicle-to-grid (V2G) services. We use an electric power system model to explicitly evaluate the change in generator dispatches resulting from PHEV dep...
Mexico City’s bus rapid transit (BRT) network, Metrobus, was introduced in an attempt to reduce congestion, increase city transport efficiency and cut air polluting emissions. In June 2005, the first BRT line in the metropolitan area began service. We use differences-indifferences and quantile regression techniques in undertaking the first quantitative policy impact assessment of the BRT system...
BACKGROUND In our previous experimental studies, we found evidence for the increase of nitric oxide (NO) formation immediately after blast injury. In the present study we investigated whether NO overproduction was a trait for the period immediately after blast injury in humans. Concomitant metabolic disturbances were also studied, and compared to the alterations in other traumatized patients. ...
C is in the midst of the largest and fastest period of economic growth in global history. While this growth at 9 10% GDP per year has lifted hundreds of millions of people from poverty, the all out prioritization of economic prosperity has created serious air and water pollution that are affecting the health of the local population, and also have increasing global climate impacts. A World Healt...
