Hurricane and ReCyclone® systems for emission control and value added product recovery
The development of high efficiency Hurricane and ReCyclone® systems allows their application either for emission control or value-added product recovery. The purpose of this paper is to present not only the performance of these systems, but also a model to predict in a more realistic way the collection efficiency of a gas cyclone with or without partial recirculation. Some experimental ...

Meeting Emission Control Through Improved Actuation
Reducing fugitive emissions, particularly methane, is a major priority in the fight against climate change. Although valves and actuators have been the focus for reduction efforts because valve leakage accounts for more than half of total fugitive emissions, the problem is mainly old valves that weren’t designed using the latest materials and technologies. New technologies can also help to ...

H2S Emissions Control at Geothermal Plants
The LO-CAT® II process is used to control H2S emissions and reduce odors at geothermal power plants. Geothermal steam, considered to be a clean and environmentally friendly source of energy, is produced when water seeps into high temperature, high pressure formations below the earth's surface. The steam is brought to the surface through production wells and then expanded through a ...

Hurricane Cyclones: Dedusting and Emission Control - Case Study
Dust from cutting and scarfing operations on pressboard Foreword In 2010, Advanced Cyclone Systems was approached by a Portuguese energy industry, Efacec Energia, to capture the pressboard’s dust coming from the cutting and scarfing operations. The previous filtering system, based on bag filters, was outdated as well as with problems of operation and maintenance. With the predicted ...

Greenhouse Gas Emissions Control
Most of the time, people think about Greenhouse Gas (GHG) emissions with carbon dioxide, which is the most common of the GHGs. While fairly typical, carbon dioxide isn’t the only GHG U.S. Environmental Protection Agency (EPA) regulates. Since EPA has begun regulating GHG emissions under its Clean Air Act authority, sources of emissions from others may require add-on air pollution control ...

Conception of an environmental technology data bank
For documentation, analysis and application of the state of the art and its development in environmental technologies, an information system should be conceived by using modern information and communication techniques. Within this project the pilot phase is being carried out, in which in co-operation with the established working party (industry, host and authorities) a test data bank is being ...

GE Aircraft Engines - Case Study
Mech-Chem engineered, designed, and constructed two Air Emission Control Systems for the plant's Meltout Operations. The systems are non-aqueous processes which were designed to contain and remove metallic contaminants with a particle size of 0.3 microns or larger. Air Emission Control System Mech-Chem provided GE Aircraft Engines with the design, engineering, construction, installation, and ...

EPA Increases Ammonia Emissions Control
Concern about ammonia emissions in the air and the water continues to grow, both officially and unofficially. As U.S. Environmental Protection Agency (EPA) moves to further reduce ammonia concentrations in surface waters, common water treatment methods transform what had been a water pollution problem into an air pollution issue. Earlier this year, EPA released its draft Integrated Risk ...

Panelboard emission control: An historical perspective
Sometimes the best view of the future can be seen from the past. That's why we've written this paper. We believe that an understanding of the history of emission controls in the panelboard industry will help everyone understand how this industry got to where it is and what the future holds. This account focuses on the evolution of technology devoted to the control of air pollution emissions from ...

Metal Coating Emission Control
As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking plant in the Midwest had been using a thermal recuperative oxidizer with direct heat recovery for control of emissions from its sheet coating lines. ...

Potential of biofiltration for VOCs emission control and safety aspects
Directive 99/13/EC on the emission of Volatile Organic Compounds (VOCs) is impacting on several industries in Italy, as well in other EU countries. Many small enterprises have to invest in new control systems and need to be helped to choose an appropriate and safe technology. As VOCs are highly flammable compounds, high concentrations in emission flows can pose a fire and explosion hazard if ...
