Impact Of A Pre-combustion Retrofit Device On Vehicular Emissions: A Case Study
(Civil & Environmental Engineering, 2007-08-23)
Vehicular emissions are a major cause of air pollution in the cities worldwide. Increased numbers of vehicles and the vehicle miles traveled by them every year means that the emissions are going to have a detrimental effect ...
Determination Of Safe Buffer Width Of Roadway To Protect Human Health Form Harmful NOx Exposure
(Civil & Environmental Engineering, 2007-08-23)
According to the 2004 EPA Trends Report, US on-road transportation sources emit 36% of nitrogen oxides (NOx), 63% of carbon monoxide (CO), and 29% of volatile organic compounds (VOCs). This research determines a safe roadway ...
Comparison Of Adsorption Capacities Of Nanoadsorbents With Conventional Activated Carbon For Volatile Organic Compounds
(Civil & Environmental Engineering, 2007-08-23)
This research explores the potential for using single wall carbon nanohorns (SWNHs) for adsorption of volatile organic compounds (VOCs) categorized as hazardous air pollutants and which contribute to ground level ozone ...
Removal Of Carbonyl Sulfide Using Compost Biofilter: Measurement Of Removal Rates And Elimination Capacity In Conjunction With Hydrogen Sulfide
(Civil & Environmental Engineering, 2007-08-23)
A lab study using biofiltration was conducted using three PVC columns as biofilters, with hardwood chips and compost as the media. Previous research determined the removal efficiency of carbonyl sulfide alone. (Nawal, 2004) ...
Photocatalytic Degradation Of VOCs, Toxics And Odors From Air Emissions Of Wastewater Treatment Plants And Municipal Solid Waste Landfills
(Civil & Environmental Engineering, 2007-08-23)
The 1990 Clean Air Act Amendments (CAAA) require more stringent controls of sources of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs). Air quality managers at the state level are responsible for ...
Trends Of Vehicular Emissions Due To The Effect Of Ethos® FR As Fuel Additive
(Civil & Environmental Engineering, 2007-08-23)
The main objective of this research was to observe if the addition of the fuel additive Ethos Fuel Reformulator significantly reduced the emissions of CO, CO2, HC and NOX from a light duty vehicle. Data collection was ...
