Controlling particulate emissions
Cloud chamber technology uses electrically charged water droplets to attract fine particles and remove them from exhaust streams. At the Saint-Gobain Advanced Ceramics Boron Nitride (formerly Carborundum) plant in Amherst, N.Y., the technology has exceeded required performance criteria and helped a plant with an air pollution control problem remain a part of the local industrial ...

Filters for Light Duty Diesels
EA particulate filter can effectively eliminate tailpipe particulate emissions from diesel cars. Johnson Matthey’s work in this area has led to a new, third generation of catalysed diesel particulate filters that are highly durable and cost optimised. They have the potential of providing significant health benefits through elimination of particulate emissions into the environment, ...

Particulate emission monitoring in the Mineral industry - Case Study
Application The grinding of China Clay can be processed by ring roller mills providing efficient control of product size. With the addition of a new mill on a China Clay production site, particulate emission monitoring from the baghouse to the atmosphere was required to meet regulatory requirements. With an ELV of 10 mg/m3 and an MCERTS certified product installation specified by the regulator, ...

World emissions and economic growth: application of non-parametric methods
The Environmental Kuznets Curve (EKC) hypothesises an inverse U-shaped relationship between a measure of environmental pollution and per capita income levels. In this study, we apply non-parametric estimation of local polynomial regression (local quadratic fitting) to allow more flexibility in local estimation. This study uses a larger and globally representative sample of many local and global ...

An application of backscatter Lidar to model the odour nuisance arising from aircraft tyre smoke
A Rapid-Scanning Backscatter Lidar (RASCAL) has been deployed at Heathrow and Manchester Airports to collect backscatter data from particulate emissions in the wakes of several hundred flights. The principal aim of these measurements was to characterise the dispersion of the engine exhausts, but it was found that tyre smoke was also visible, giving a signal substantially greater than that from ...

Argueso & Co. Achieves 99% Efficiency for Particulate Emissions Using Whirl Wet
M. Argüeso & Co. produces casting wax blends for the investment casting industry, wax products to stabilize parts during machining, and specialty wax blends for sculpture, jewelry and other uses. M. Argueso moved from Mamaroneck, New York to Muskegon, Michigan in 2005, subjecting the facility to Michigan’s stringent air regulations. The company’s first priority was a system that would ...

Pigment particulate emissions monitoring in a chemical plant in Indonesia - Case Study
What was the Challenge of the Customer? A chemical plant in Indonesia that produces pigments for various applications faced the challenge of avoiding emissions of particulate matter into the air, in case of failure of their bag filters. Indeed, there had been problems with the bag filter in the past. And in those situations, a lot of pigment particles were sent to the neighborhood, what caused a ...

Fabricated Parts for Air Infiltration Sealing
Air leakage control is a critical activity for a wide spectrum of businesses. Contractors may be tasked with sealing building envelopes to prevent heat loss, thus energy wastage. Specialty manufacturers may be called upon to deliver precision fabricated parts that target specific pain points and air leakage paths. The only way to gain a deep understanding of where air infiltration, heat losses, ...

Dust monitoring solutions for cement plants - Case Study
Particulate emissions from cement kilns have been reduced significantly over the last few decades due in part to ever-tightening regulatory controls including the lowering of emission limit values (ELVs) and the associated increase in installations of highly effective filtration systems which require higher quality monitoring. Main emissions to air are from the kiln system Additional ...

Air–quality impact of PM10 emission in urban centres
This paper calculates a detailed inventory of PM10 emissions in the urban area of Mendoza, Argentina, and evaluates the impact of such emissions by using the CALPUFF dispersion program. It includes direct and indirect emissions from mobile sources; emissions from industrial sources and fugitive emissions from unpaved road and dust production from bare land. The main results show the relevance of ...

A quantitative approach to the traffic air quality problem: the traffic air quality index
The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis (“hot-spot” analysis for nonattainment areas) as defined by 40 CFR 93.123. This paper is a follow-up to a study published earlier regarding the development of the TAQ model. This paper shows how ...

The Many Dimensions of Uncertainty Analysis in LCA (PDF)
Uncertainty comes into play when analysts, databases, or reports make statements or assertions about something in the real world based on Life Cycle Assessment methods and data. These statements or assertions can be either quantitative or qualitative. An example of a quantitative statement within LCA might be, “the total ‘embodied’ carbon dioxide emissions caused by generating a kilo-watt hour in ...

Evaluation of total particulate matter emission factors for copper slag in dry abrasive blasting
Abrasive blasting was performed in enclosed conditions to evaluate the effect of blast pressure, feed rate and surface contamination on Total Particulate Matter (TPM) emission factors for copper slag. Stack sampling methods were used to collect uncontrolled TPM. Emission factors were calculated as grams of TPM emitted per pound of copper slag used (g/lb) and grams of TPM emitted per square foot ...

School bus retrofits one local air
The Hamilton County Department of Environmental Services, a local air agency covering the Greater Cincinnati Area in Southwest Ohio, has experienced many successes and failures obtaining grant money to fund school bus retrofits. However, seven years of persistent work has paid-off enormously. The adverse health effects of diesel exhaust were making national headlines in the early 2000s. The U.S. ...

Roadside particulate levels at 30 locations in the Kathmandu Valley, Nepal
Roadside particulate levels (PM10) at 30 locations throughout the Kathmandu Valley, Nepal are reported. There were seven sampling cycles from January to December 1999. PM10 levels ranged between 1000 and 6000 µ/m³ for 1-h sampling. There was no consistent trend in PM10 levels with respect to monitoring cycle, average precipitation or wind speed. There is no WHO guideline for PM10 (no safe ...

Analysis of point source emissions in the Texas-Mexico border region
Pollutant emissions in the Texas-Mexico border were investigated using an emission database that covers 25 Texas counties and the states of Coahuila, Chihuahua, Nuevo Leon and Tamaulipas in Mexico. Major emissions are from energy generation, mainly from two coal-fired facilities in Coahuila, which also generate most of carbon dioxide. Texas exhibits a larger concentration of sources; around ...

Innovative Dryer and Emission Control System at a Particleboard Installation
In 1989, Bohemia Corporation installed a new primary drying system and also air pollution control equipment at their particleboard plant in Eugene, Oregon. The drying system was composed of a Westec America triple-pass rotary drum dryer fired by a Coen sanderdust burner. The primary and secondary particulate collectors installed were also of a Westec America design. The tertiary air pollution ...
