Performance of the low-emission flare

by Hofstetter BV  (Aug. 4, 2016)

Job report / Elbisgraben (Bale / Switzerland) The summer of 1992 had finally arrived. The 5MW low emission furnace in the district heating station Liestal was ignited, supplied with landfill gas from Elbisgraben landfill. Since then the plant has been running continuously and the comprehensive measurements taken, verify that all targets aimed at ...

Ethylene removal through oxidation in EthylClean Machines versus forced air through ozone

by Bioconservacion SA  (Aug. 16, 2016)

Fruit constantly emits ethylene inside the chambers. To efficiently reduce the concentration of ethylene in these spaces, it needs to be eliminated at a speed that is faster than the production ratio of the fruit. This is achieved when the airflow that passes through the machines in one hour is equal to the volume of the chamber. Depending on the ...

The landfill gas collection, utilisation and surplus gas combustion acting in unison

by Hofstetter BV  (Aug. 4, 2016)

In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, ...

Air Emissions/Off-Gas Treatment

by Federal Remediation Technologies Roundtable  (Jan. 1, 1997)

A number of technologies have been widely applied for removal of VOCs from off-gas streams. However, the application of these technologies to off-gases from site remediation may be quite limited. Biofiltration has been widely applied for VOC destruction in Europe and Japan, but it has only recently been used in the United States. Catalytic and ...

Real-time air emissions monitoring

by Wood Group Mustang, Inc.  (Sep. 1, 2008)

Due to increasingly rigorous requirements for regulatory and permit compliance, organizations are seeking more from all compliance support systems. The ability to expand systems to encompass new, or migrate existing, regulatory calculations used to monitor environmental performance is vital. Planning strategically for a scalable and sustainable ...

The Emissions Trifecta: Combining Title V, Air Emissions and GHG Reporting

by Enviance, Inc.  (Jan. 9, 2010)

With greenhouse gas (GHG) and other pollutants meeting increased scrutiny worldwide, governmental agencies have put multiple regulations and environmental programs in place to tackle this growing problem. But effectively tracking and managing data for Title V, an air emissions inventory and the EPA’s new mandatory GHG reporting rule can ...

Air emissions benchmarking report case study

by M.J. Bradley & Associates LLC  (Oct. 31, 2013)

In 2008, 2010, 2012, and 2013, MJB&A managed the production, budget and release of a collaborative report entitled Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States.  The 2013 report was jointly published by Bank of America, Ceres, Entergy, Exelon, the Natural Resources Defense Council, ...

Data Requirements Air Emissions/Off-Gases

by Federal Remediation Technologies Roundtable  (Jan. 1, 1997)

Predictive modeling may be usefelected to represent the system (e.g., SVE treatment, incinerator, etc.), and site and contaminant informaul in estimating emissions from a site or treatment system. An appropriate theoretical model is stion is used to estimate gross emissions. Because many variables affect emission rates, this approach is limited by ...

Air emissions impact measurements at a perchloroethene remediation site

by VOC Technologies  (Feb. 24, 2010)

As part of an U.S. EPA time critical removal action, an air monitoring system was established to measure real-time impacts of perchloroethene (PCE) on the surrounding areas. The soils and groundwater beneath the site (located in West Fargo, North Dakota) were treated using in situ heating of soil and groundwater, with the produced vapors ...

National Air Pollutant Emission Trends, 1900-1998

by US EPA - Environmental Protection Agency  (Mar. 1, 2000)

 Executive Summary What information is presented in this report? This report presents the United States (U.S.) Environmental Protection Agency’s (EPA) latest estimates of national emissions for criteria air pollutants: carbon monoxide (CO), nitrogen oxides (NOX ), volatile organic compounds (VOC), sulfur dioxide (SO2 ), particulate matter ...

Controlling Hazardous Air Emissions With A Catalytic Oxidizer

by The CMM Group, LLC  (Sep. 1, 2002)

As the full effect of the Federal Clean Air Act (CAA) Amendments continue to impact today’s industry, many companies will be required to install new or additional air pollution control equipment. With well over twenty years of proven success, catalytic oxidation is a popular method for controlling volatile organic compound (VOC) emissions.During ...

Recovering Valuable Chemicals from Air Emissions

Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions ...

Can Composting BMPS Reduce Air Emissions?

by BioCycle Magazine  (Jan. 1, 2004)

Imagine a scenario where all yard trimmings collected for recycling have to be received, processed and composted under the cover of a building. It would be tough for most yard trimmings composting facilities to survive the expense. Yet this situation could have occurred in Southern California. At one point, the South Coast ...

A cost-effective method for controlling compost air emissions

by Engineered Compost Systems  (Nov. 1, 2007)

In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. ...

Concentrations of air pollutants constant despite drop in emissions

by NILU - The Norwegian Institute for Air Research  (Nov. 19, 2007)

Concentrations of ozone and particulate matter, two harmful airborne pollutants, have not improved since 1997 despite substantial cuts in emissions of air pollutants across Europe, says a new EEA report where Norwegian Institute for Air Research (NILU) has co-ordinated and are editor ...

Clearing the air: the use of bio-oxidation for industrial air emissions control

The wood products industry began rather ardous road to emissions control in the early 1990s with the first installation of a thermal oxidizer (an RTO) at a California MDF facility, for volatile organic compound (VOC) control. During the ensuing years, virtually every panel board facility has had to control emissions of VOCs, and up until the last ...
