Abstract:
In this work, a novel generator of gas mixtures previously numerically investigated and based on axial gas pulses coupled to a micromixer has been conceived, manufactured, and validated. Standard gaseous pollutant mixtures and pure nitrogen or pure air were introduced in a microdevice designed to generate alternating axial gas pulses which were downstream homogenized by means of a multi-stage modular micromixer. The dilution, and therefore the final pollutant concentration, was controlled by two parameters: the ratio between the times of each of the two gas pulses and the partial pressure of t

Abstract:
The production of biodiesel as an alternative fuel and its use as a mixture and other additives are presented. In the present research work, additive blends with diesel biodiesel from algae oil are physically characterised and an analysis of pollutant emissions is carried out when used in an ignition engine by compression. The measurement of pollutant emissions is carried out through a combined emission analyzer adapted to a system of valves attached to the experimental facility. The properties of each mixture with the polluting emissions are compared with that of the reference diesel. It was

Abstract:
The ecological impacts of emerging pollutants such as pharmaceuticals are not well understood. The lack of experimental approaches for the identification of pollutant effects in realistic settings (that is, low doses, complex mixtures, and variable environmental conditions) supports the widespread perception that these effects are often unpredictable. To address this, we developed a novel screening method (GSA-QHTS) that couples the computational power of global sensitivity analysis (GSA) with the experimental efficiency of quantitative high-throughput screening (QHTS).

Background: Fine particulate matter (PM2.5) occurs within a mixture of other pollutant gases that interact and impact its composition and toxicity. To characterize the local toxicity of PM2.5, it is useful to have an index that accounts for the whole pollutant mix, including gaseous pollutants. We consider a recently proposed pollutant mixture complexity index (PMCI) to evaluate to which extent it relates to PM2.5 toxicity. Methods: The PMCI is constructed as an index spanning seven different pollutants, relative to the PM2.5 levels. We consider a standard two-stage analysis using data from 26

One alternative measure to minimise the stormwater runoff volume and its pollutants and reduce impervious areas is to use permeable pavement.

Abstract:
Exhaust gas recirculation (EGR) is the most effective and practical method for reduction of NOx emission in Internal Combustion Engines. However, improper application of EGR in the engine causes higher power loss, excessive specific fuel consumption (SFC) and an increase in the concentration of other pollutants. For this reason, the amount and temperature of EGR must be tailored for each engine in order to get optimum performance and emission results. In this research work, after comparison of hot and cooled EGR for an S-I engine, pollutant behavior has also been studied around Dew point tempe

Abstract:
Coal combustion with oxygen is considered one of the most effective methods to improve thermal efficiency, reduce pollutant emissions such as NOX, and facilitate capture of CO2 pollutant from flue gas. This paper presents calculations of oxygen coal combustion with flue gas recirculation. The coal is burned in oxygen/CO2/H20 mixture. In addition to solving transport equations for the continuous phase (gas), a discrete second phase (spherical particles) is simulated in the Lagrangian frame of reference. Reaction is modeled by a mixture fractions/PDF approach. Discrete phase modeling is used for

Abstract:
In this work a model for transport phenomena in an environment representing the atmosphere containing a pollutant is presented by considering mass and linear momentum conservation for the air-pollutant mixture as well as the mass balance for the pollutant. The resulting mathematical description consists of a nonlinear system of hyperbolic equations that admits discontinuities in addition to smooth or classical solutions. The Riemann problem associated with a class of problems describing the transport of a pollutant in an ideal gas with constant temperature with a discontinuous mass density dis

Abstract:
Homogeneous-charge, compression-ignition (HCCI) combustion is triggered by spontaneous ignition in dilute homogeneous mixtures. The combustion rate must be reduced by suitable solutions such as high rates of Exhaust Gas Recirculation (EGR) and/or lean mixtures. HCCI is considered to be a very effective way to reduce engine pollutant emissions, however only a few production engines have been built. HCCI combustion currently cannot be extended to the whole engine operating range, especially to high loads, since the use of EGR displaces air from the cylinder, limiting engine mean effective pressu

Abstract:
Large-bore natural gas two-stroke engines with lean-burn technology have been integral to the North American pipeline network for many years and will remain crucial for future gas transportation. As research focuses on achieving lower lean ignition limits, pre-combustion chambers have gained attention as a promising method to enhance combustion stability and engine reliability. However, retrofitting existing platforms with pre-combustion chambers may not always be financially viable, which calls for further exploration of alternative technologies that could reduce methane emissions from two-st

Abstract:
Tire rubber waste (TRW) is a complex mixture of materials, such as rubbers, steel, textile fibers, carbon black, and other additives. Its polluting capacity is a severe environmental problem, especially in landfills and waste management processes. As a practical solution to mitigate TRW’s environmental impact, thermoplastic elastomers (TPE) commonly reuse the ground tire rubber (GTR). This work presents an in-situ devulcanization of ground tire rubber (DGTR) and re-vulcanization of devulcanized ground tire rubber using dicumyl peroxide (DCP) and waste ethylene-vinyl-acetate (wEVA).
