What is the size distribution and sources of particles in ambient air?
The particle sizes in the ambient air are ranged from 1 nanometer to slightly more than 10 micrometers. There are three modes: coarse, fine and nano. The course mode particles are road dusts, spores and pollens. The minimum sizes of these particles are 1 to 3 micrometers. The fine mode particles are generally secondary particles formed from reactions such as smoke, sulfates, nitrates, ammonium ...

What is Boiler MACT & CISWI MACT? - Case study
Boiler MACT regulates production of carbon monoxide (CO). If CO is managed by combustion conditions, NOx production increases. The best strategy for Boiler MACT compliance is to control CO in the boiler and allow the UltraCat Catalytic Filter System to remove NOx in the flue gas. CISWI MACT regulates air pollutants from commercial and industrial solid waste incineration units, for: ...

3 Questions: Amanda Giang on controlling Mercury Pollution in India and China
Original story at MIT News MIT graduate student studies how a new U.N. treaty could affect mercury emissions from coal power plants in Asia. The Minamata Convention on Mercury, a global treaty adopted by the United Nations in 2013, aims to reduce worldwide mercury pollution by setting limits on specific pollution sources and prohibiting new mercury mining. Certain aspects of the treaty are ...

End-user GHG emissions from energy
The objective of this report (1) is to help improve the understanding of past greenhouse gas (GHG) emission trends in the energy sector from the demand or end-user side. To do this, the report develops a methodology to redistributes emissions from energy industries to the final users (by sector) of that energy. This reallocation is done on the basis of Eurostat's energy balances and GHG ...

The Future of Secondary Materials as Fuel
Many questions related to the regulatory status of facilities that use secondary materials as alternative fuels are anticipated to be answered in 2010. In simple terms, if a combustion source uses a secondary material that is characterized as solid waste as an alternative fuel, then that source could be subject to a Clean Air Act (CAA) Section 129 standard. If the same source used a secondary ...

Gasmet GT90 Dioxin+ Is an Effective Solution for Dioxin Sampling
In this article we introduce you to the world of continuous dioxin monitoring and the Gasmet GT90 Dioxin+, which is an exceptionally robust dioxin sampling system. Did you know that it was designed to sample even the lowest dioxin and dioxin-like compound concentrations in harsh industrial environments, even in subfreezing conditions? In addition to dioxins, the system is capable of measuring ...

Mobile Stationary Source Emissions Testing, Coming to a Facility Near You?
Last week, Antea Group had the unique opportunity to perform a RATA (relative accuracy test audit) of the emissions from a thermal oxidizer at an ethanol production facility located in Minnesota using a state-of-the-art mobile testing laboratory. During this RATA audit, actual stack emissions levels (including NOx, SOx, CO2, CO, O2, flow rate, temperature, velocity and pressure) from the thermal ...

Global Warming - A Hot Topic in the Northeastern States
Global warming has been a hot topic for many years; although speculation existed regarding its correlation to human activities. Recent studies demonstrate, however, that human activities likely contribute to global warming, and policymakers from all over the world are proposing programs to slow down the warming trend. The emphasis has been placed on programs that reduce greenhouse gas (GHG) ...

Impact of CO2 Emission Trading Schemes on Residual Waste Management
ABSTRACT The EU-Emission trading scheme (ETS) in its current design hardly affects residual waste management directly: methane from landfill-sites is not included although it is one of the “Green-House-Gases” (GHG) of the Kyoto Protocol, CO2-emissions from waste incineration plants are generally exempted from the regulation of the directive and emissions from combustion of landfill-site gas can ...

EPA proposes updates to CISWI rules
On June 4, 2010, the U.S. EPA proposed updates to the Standards of Performance for New Stationary Sources (NSPS) for Commercial and Industrial Solid Waste Incineration (CISWI) Units (NSPS Subpart CCCC) and Emission Guidelines (EG) for Existing CISWI Units (EG Subpart DDDD), collectively referred to as the "CISWI Rules." In order to describe the proposed updates to the CISWI Rules, it is necessary ...

Prepare now for the carbon tax bill or face hefty fines
To avoid massive financial penalties, South Africa-based industries need to immediately prepare for the implementation of the Carbon Tax Bill, warns Roger Rusch, CEO of IWC (Industrial Water Cooling). In November 2015, the National Treasury published the Draft Carbon Tax Bill for public comment. Once implemented, the Bill will penalise companies with excessive Green House Gas (GHG) emissions, ...

Customer stories: HURL and FPI's Innovative Partnership Lead the Way to Sustainable Fertilizer Production
The fertilizer industry plays a crucial role in India's agricultural sector, which is the backbone of its economy.However, the production of fertilizers comes with its own set of environmental challenges. The fertilizer industry releases various pollutants into the environment, such as ammonia,sulfur dioxide, nitrous oxide, and particulate matter, which can have adverse effects on human health ...

VOC monitoring on stationary sources: from environmental policies to technical solutions
In the past, the primary origin of local air pollution has been emissions from stationary sources. These sites include power generating plants, oil refineries, chemical plants, steel factories, cement and glass manufacturing companies, space heating, and many other industries. Pollutants are emitted into the air from these plants through fossil fuel combustion, chemical processes, and the ...

Air Particulate Monitoring – PM1
What is PM1 “PM” (Particulate Matter) is not a single pollutant but refers to a complex mixture of solids and aerosols. Which are of varying shape, size, and chemical composition. Which may contain many chemical species like organic compounds, inorganic ios, metallic compounds, elementary carbon, etc. These atmospheric particles are definable by their diameter for air quality ...

What is a spray tower?
Spray tower, also known as scrubber, wet scrubber, is waste gas treatment equipment. The exhaust gas is fully contacted with the liquid, and the concentration of the waste gas is reduced by using its solubility in water or chemical reaction, so as to become a clean gas that meets the national emission standards. It is mainly used to treat inorganic waste gas, such as sulfuric acid mist, hydrogen ...

Smart LDAR — more cost-effective?
On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

States propose attainment designations for the new 1-hour So2 NAAQS
The U.S. EPA revised the primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2) on June 2, 2010 by implementing a new 1-hour standard of 75 parts per billion (ppb) (calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations). Based on an evaluation of the risks posed by acute exposure to SO2, EPA ...
