How do Factories Cause Air Pollution?
The modern world, bathed in the conveniences of industrialisation, is paradoxically paying the price for its advancements. The factories that once symbolised progress and prosperity have now, to some extent, become synonymous with environmental degradation. This isn’t merely a topic for debate in academic circles; it’s a tangible, pervasive issue that impacts the ...

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 ...

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 ...

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 ...

What is the environmental impact of waste tyre pyrolysis plants?
In modern life, the environment has always been our concern. Waste tyre pyrolysis plant can convert waste tyres into fuel oil, which is good to prevent the pollution of waste tyres. Maybe you want to know whether the waste tyre pyrolysis plant will produce secondary pollution while processing. I can tell you categorically that the environmentally friendly equipped waste tyre pyrolysis plant have ...

Glass manufacturer controls gas ratios - Case Study
For a specialty glass manufacturer that constructs high-quality glass containers for the pharmaceutical and analytical industry, manual control of air and natural gas flow to the burner tip had resulted in unacceptable levels of rejected material, as well as excessive gas consumption. The process engineers were seeking methods to improve glass quality, reduce raw material waste, and increase ...

Modernising gas fired power plant boiler damper drives and damper bearings - Case Study
Sector: Power Generation Category: Fluid Power Actuators, Services Products: PM/DM, Retrofit Overview The challenge of modernising the instrumentation on an old utility boiler can be overwhelming, especially when the boiler was originally commissioned in 1964. Power utility base load preference has historically been the domain of the larger coal fired boilers. That has been the desired ...

Impact of ambient air temperature and injection timing on reduction of engine out emissions of DI diesel engine operating under the influence of oxygen enriched hydrogen gas
The present experimental work is a study of the impact of ambient air temperature and the injection timing of diesel fuel on reduction of engine–out emissions of DI diesel engine, operating under the influence of oxygen enriched hydrogen gas. Here the oxygen enriched hydrogen gas was produced by the process of water electrolysis. The produced gas was aspirated into the combustion process of ...

Recuperative Thermal Oxidizers and midstream natural gas processing - Case study
A large midstream natural gas processing facility was in urgent need of a VOC abatement device for their newly expanded gas processing plant. The operator was expanding their operations at an unusually fast pace. In the process of bringing on new gas treating capacity, they found themselves up against the limits of their current operating permit. Any new sources would put them over their limits ...

Pharmacuetical Company chooses the QUADRANT NRV Thermal Oxidizer - Case study
Faced with meeting the needs of their Pharma Industry MACT Standards, one Fortune 100 Pharmaceutical Manufacturer called on Catalytic Products International, Inc. The challenge for Catalytic Products International was to design a system that was able to process the ultra-high LEL (high concentration of VOC’s) and deal with corrosive acids produced in the process off gas and the ...

Survey of standards related to gas detectors
Recent events both on- and off-shore shine a bright light on the need for attention to safety and to hazard reduction, prevention, and mitigation. Errant combustible or toxic gases can injure and kill quickly. Therefore, mitigation of these hazards must be fast and sure. Globally, governmental and regional authorities take gas detection and system integration very seriously and require that the ...

Defining solid waste
Simultaneous to the publication of the final National Emission Standards for Hazardous Air Pollutants for Boilers (the Boiler NESHAP) and the Commercial and Industrial Solid Waste Incinerator (CISWI) Rules, EPA issued a new regulation that for the first time defines what materials are a non-hazardous solid waste when combusted. This rule, Solid Wastes Used as Fuels or Ingredients in Combustion ...

Final CISWI rule
On March 21, 2011, in parallel with publication of the Boiler National Emission Standard for Hazardous Air Pollutants (NESHAP) rules and the Non-Hazardous Secondary Material (NHSM) rule, EPA promulgated the final updates to the New Source Performance Standards (NSPS) and Emission Guidelines (EG) for Existing CISWI Units, collectively referred to as the “2011 CISWI Rules.”1 The 2011 ...

Federal transport rule — the “new cair” round 1
On August 2, 2010, EPA proposed the long- awaited replacement for the Clean Air Interstate Rule (CAIR), which was rejected in 2008 by the D.C. Circuit Court of Appeals. Now called the Transport Rule (TR) by EPA, the new rule revises the CAIR approach to conform with the court ruling. In this first version (Round 1) of TR, overall emission budgets for NOX are similar to the initial period in CAIR; ...

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 ...

To MACT and Beyond case study
In the 1970s, FMC Corp., a chemical manufacturer headquartered in Philadelphia, began operating a high-efficiency thermal destruction facility to dispose of hazardous liquid wastes at its Baltimore pesticide manufacturing plant. The facility used a thermal oxidizer with a rapid quencher and packed tower scrubber to remove air pollution emissions. The system was upgraded in the early ’80s ...
