Cost-Effective Reduction of NOx Emissions from Electricity Generation [PDF]

This paper analyzes the benefits and costs of policies to reduce nitrogen oxides (NOx) emissions from electricity generation in the United States. Because emissions of NOx contribute to the high concentration of atmospheric ozone in the eastern states ...

Cold Gas Plasma Induces Platelet Activation and Hemostasis in Native and Anticoagulated Human Blood

Advanced NanoBiomed Research, EarlyView.
Cold physical gas plasma induces platelet activation and hemostatic responses in native and anticoagulated human blood. Treatment efficacy depends on plasma parameters, including gas composition, distance, and exposure mode, which govern reactive species delivery and energy transfer.

The Effect of Sintering Flue Gas Composition on NO Reduction in Coke

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The strategy of substituting combustion air with sintering flue gas in circulating fluidized bed (CFB) systems provides a low‐cost and highly efficient approach for the purification of sintering off‐gas. In this work, coke was employed as the reducing agent, and a high‐temperature vertical tube furnace was used to simulate the dense‐phase ...

A NOx Emission Model Incorporating Temperature for Heavy-Duty Diesel Vehicles with Urea-SCR Systems Based on Field Operating Modes

Atmosphere, 2019
The selective catalytic reduction (SCR) is the most commonly used technique for decreasing the emissions of nitrogen oxides (NOx) from heavy-duty diesel vehicles (HDDVs). However, the same injection strategy in the SCR system shows significant variations

U.S. Emissions Trading Markets for SO2 and NOx [PDF]

The U.S. Clean Air Act Amendments of 1990 initiated the first large experiment in the use of market-based regulation to control environmental problems with the introduction of an emissions trading program for sulfur dioxide emissions.

Global Inventory of Nitrogen Oxide Emissions Constrained Space-Based Observations Of NO2 Columns [PDF]

, 2003
sions (37.7 Tg N yr #1 ) agrees closely with the GEIAbased a priori (36.4) and with the EDGAR 3.0 bottom-up inventory (36.6), but there are significant regional differences. A posteriori NO x emissions are higher by 50 -- 100% in the Po Valley, Tehran,

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...

Rising importance of agricultural nitrogen oxide emissions in China’s future PM2.5 pollution mitigation

npj Climate and Atmospheric Science
Controlling ammonia (NH3) emissions through agricultural management has been recognized as effectively mitigating fine particulate matter (PM2.5) pollution in eastern China. However, agricultural nitrogen oxide (NOx) emissions are often overlooked.

The Chesapeake Bay and the Control of NOx Emissions: A Policy Analysis [PDF]

Nitrogen oxide emissions not only affect air quality but have recently been found to be an important source of nitrate pollution in the Chesapeake Bay. This analysis examines the costs, emissions, source-specific and location-specific allocations of NOX ...
