SCR Long-Term Durability Proven in U.S. Field Trials
In the Spring 2003 issue of Global Emissions Management,we unveiled the Compact SCRT® from Johnson Matthey. In this issue,we provide an update on SCR durability trials, taken from paper 2004-01-1289 given at the SAE 2004 World Congress in Detroit. Selective Catalytic Reduction (SCR) has emerged as the preferred solution for achieving the Euro 4 limits, which come into force in ...

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 ...

The need for motorcycle emission control program and safety laws in Liberia
Since the end of the civil war, the Liberians demand for a sustainable future and economic growth seem to be optimistic and promising in that many of them have embarked on a path to self sustainability by exploring new ideas and taking on opportunities that have the potential to provide some sort of income that tend to lift their self esteem. The introduction of motorcycles into the Liberian ...

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 ...

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 ...

Recent degassing jobs - case study
PURGIT has recovered hundreds of tons of tank vapor. Our process takes tank vapor and recovers it by condensing the vapor to liquid that can be recycled or sold. PURGIT does not waste valuable natural resources. The PURGIT process condenses tank vapor meeting environmental regulations and the recovered condensate is available for recycling. This is the most interesting and sophisticated vapor ...

Case No : 601: Reducing NOx emissions from Nirtic Acid Manufacturing Plants with NOx Abatement or NSCR
NOx Abatement is a Non-Selective Catalytic Reduction (NSCR) technology that has a long and proven track record for controlling NOx emissions from nitric acid manufacturing plants. It can be used to alter the NO to NO2 balance (decolourization) or to eliminate NOx through catalytic reaction with a fuel as a reductant. Nitric Acid Production The first part of the nitric acid process involves ...

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 ...

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. ...

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 ...

NSCR, SCR Systems Reduce Emissions
MALVERN, PA.–The implementation of the federal government’s new source performance standards (NSPS) and even stricter regulations in some air quality districts administered by state and local governments are significantly tightening control requirements on exhaust emissions from stationary sources. Emissions control from stationary engines has been mandated to varying degrees over the years, ...

Air as Clean as the Driven Snow
While California is the most populated state in the nation, it is also home to some of America’s most natural and pristine wilderness and recreation areas. One such venue is the Snow Summit Ski Resort in Big Bear Lake. Situated just over two hours from Los Angeles, Snow Summit is a fullservice winter resort that opened in 1952 and operates an average of 142 days a year. Though situated at an ...

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 ...
