High O 3 episodes in Thailand’s Bangkok Metropolitan Regions: sources, spatio-temporal variations and associations with O 3 precursors and meteorological factors
High ozone levels were often observed from December to April at suburban stations in the Bangkok Metropolitan Region (BMR). Wind direction analyses show significant roles of air masses from outside BMR on elevating the BMR O 3 levels. These air masses include biomass burning smoke from the northwestern BMR and sea spray from the Gulf of Thailand mixing with industrial emissions from the ...

Regeneration of Palladium Catalyst for Methane Abatement
Abstract: The exhaust gas of lean burn gas engines contains significant amounts of unburnt methane gas. Since methane is a strong greenhouse gas, reducing methane emissions would greatly improve the environment and provide greenhouse gas emissions credits. Oxidation catalysts containing platinum are commonly used for the elimination of non-methane hydrocarbons (all hydrocarbons except methane). ...

Development of on-line instruments for monitoring of methane and NMTHC at PPB and PPM levels without matrix effects
Monitoring of methane and Non-Methane Total Hydrocarbons (NMTHC) is an important tool for process monitoring. In the microelectronics industry, the silicon substrates (wafers) are stored in containers, named FOUP (Front Opening Unified Pod) made in polymers (PC, PEEK, COP, PEI). Such materials are able to adsorb the Volatile Molecular Contaminants (VMC) and subsequently outgas these ones in ...

Case study - Catalytic oxidizer catalyst replacement
Overview A New Jersey pharmaceutical company purchased a thermal incinerator to treat the heptane and hexane exhaust from their capsule wash system. The thermal incinerator"s "tubular" design was modified with a catalyst bed in order to reduce the system"s operational costs. Unfortunately, when operating in the catalytic mode, the oxidizer failed to provide the required 95% destruction ...

Real Driving Emissions: Meaning and Monitoring
Road traffic is a key contributor to ambient air pollution in many parts of the world today. Throughout the years, different legislative efforts have been made to reduce pollutant emissions, both at national and international levels. One of the recent steps taken, is to introduce limits on emissions when driving in actual traffic, also called Real Driving Emissions, RDE. Accordingly, such ...

Nitrogen compressor technology
From cost savings to consistent purity - the benefits of an on-site nitrogen generator are numerous for labs requiring a reliable source of nitrogen gas. A common type of such nitrogen gas generators is one with one or more integrated compressors. But how do compressor-based nitrogen gas generators actually work? When a nitrogen generator produces nitrogen gas, the generator does not create ...

Laboratory waste gas treatment solutions
The target pollutants emitted by the laboratory are ranked in the order of potential emission intensity and control necessity: small molecular gas pollutants, specific organic pollutants (formaldehyde, xylene, methanol), biological pollutants (pathogenic microorganisms and their aerosols) ), odor, other TVOCs (ether, benzene and other macromolecular organic substances), particulate matter. There ...

Vertical distribution of VOCs and ozone observed in suburban North Carolina
As a continuing effort by the State of North Carolina to develop a State Implementation Plan for ozone control in the Raleigh Metropolitan Statistical Area, vertical measurements of C2–C10 hydrocarbons and ozone are made on a 610 meter multi-communications tower. Results signify that both long-range transport from fossil fuel combustion, petroleum exploration, petroleum refineries, and geogenic ...

Monitoring Environmental Quality
' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...
