A Modelling Approach to the Design Optimization of Catalytic Converters of IC Engines
ABSTRACT In this paper, a modelling approach to the design optimization of catalytic converters is presented. The first step of the optimization is the model-assisted sizing of catalysts. For a given inlet exhaust condition, a semi-empirical, experimentally calibrated, 0-D steady state catalyst model is employed to sort through a data base of catalysts under given restraints, yielding few ...

The experimental study of the effect of air conditioning system on internal noise within high speed train
With the increasing requirement for the travelling comfort of high speed train, the reduction in interior noise becomes very important. Noise source identification is a prerequisite to the decrease in the interior noise. To study the effects of air conditioning system on the noise inside the high speed train, the comprehensive measurement of noise and vibration was made for different carriages of ...

Roadside Survival
A routine road trip in the winter can quickly turn into a nightmare. When you are safe and comfortable inside a heated cab, the great outdoors seems far away. But a breakdown, road wreck or impassable road conditions can quickly bring you face to face with the elements. Before you set out, make sure your vehicle is in good running condition. Perform the recommended maintenance to prevent ...

Innovative Technologies Result in a More Sustainable and Energy-Efficient Total Exhaust Biological Safety Cabinet
Abstract Biological safety cabinets (BSCs) provide the primary source of containment for microbiological research. Laboratories that need containment and removal of vapors, mists and particulates will often choose a Class II, Type B2 total exhaust BSC (Type B2). Because this type of BSC must be totally exhausted to the outside through a facility’s HVAC system, it requires a great deal of ...

Types of Gas Humidifier and What They’re Used For
A gas humidifier is a device used to add water vapor to gas flow to create an exact relative humidity (RH). Relative humidity refers to the ratio of partial pressure of water vapor (pH2O) present in the gas to the equilibrium vapor pressure at saturation at a certain temperature. Gas humidifiers are often used to humidify gases that have no water-soluble components. They also humidify air which ...

What is Gas Humidification?
Gas humidification refers to the addition of water vapor to a gas flow to create a specific relative humidity (RH). Relative humidity is the ratio of partial pressure of water vapor (pH2O) in the gas to the equilibrium vapor pressure at saturation at a specific temperature. Gas humidification is frequently employed to humidify gases that do not contain components that are water-soluble, and air ...

Comparison of EGR ratios determined by four different methods for electronic re-circulation gate control
In this study, low pressure systems have been applied for exhaust gas recycling (EGR), which is applied in certain operating conditions. Induction air, exhaust gas flow, amount of exhaust gas added to the induction air, amount of carbon dioxide (CO2) in the exhaust gas, and amount of carbon dioxide in the induction air mixed with the exhaust gas, have been measured and the EGR ratio has been ...

Monitoring the variations of the oxygen transfer rate in a full scale membrane bioreactor using daily mass balances
Oxygen transfer in biological wastewater treatment processes with high sludge concentration, such as membrane bioreactor (MBR), is an important issue. The variation of α-factor versus mixed liquor suspended solids (MLSS) concentration was investigated in a full scale MBR plant under process conditions, using mass balances. Exhaustive data from the Supervisory Control And Data Acquisition (SCADA) ...

Six Ways to Improve Indoor Air Quality Now
Air quality is an important issue to anyone’s health, and many people don’t realize that their health issues and illnesses could be significantly diminished if their air quality was improved. There is much scientific evidence to suggest that the indoor air can be more polluted than the air outdoors, even in industrialized areas. When people spend eight or more hours a day in the same ...

VOC composition and ozone-forming potential of the exhaust gas of in-use motorcycles
The emission profile of volatile organic compounds (VOC) and the ozone-forming potential (OP) of the exhaust gas of six in-use motorcycles (four 4-stroke- and two 2-stroke-engines) were determined. The motorcycles were tested on a chassis dynamometer in a real-world driving cycle. The analysis involved the C2–C12-hydrocarbons as well as the aldehydes and ketones. Additionally, the regulated THC ...

VOCs exhaust gas treatment equipment is very important to purify wet scrubbers
Among the types of industrial waste gas, corrosive gases account for a certain proportion. The management of corrosive gases (such as acid and alkaline waste gas) is mostly managed by liquid absorption. This method has high purification efficiency and is simple and convenient to operate. The most commonly used equipment is waste gas treatment. Equipment to purify acid scrubber. It has the ...

Regeneration of Palladium Catalyst for Methane Abatement
Abstract: The exhaust gas of lean burn gas engines contains significant amounts of unburnt methane gas. Since methane is a strong greenhouse gas, reducing methane emissions would greatly improve the environment and provide greenhouse gas emissions credits. Oxidation catalysts containing platinum are commonly used for the elimination of non-methane hydrocarbons (all hydrocarbons except methane). ...

Biological Safety Canopy Exhaust Connection Saves Energy and Improves Overall Safety Performance
Abstract With environmental resources becoming more and more limited and energy costs on the rise, reducing energy consumption is an important consideration for every laboratory. It is especially important in light of an analysis published by the US Environmental Protection Agency concluded that laboratories consume five to 10 times more energy per square foot than typical office buildings.1 As ...

Empirical validation of a new heat stress index
Thermal stress is a well-recognised health hazard in the workplace. In addition to the health deficits, working in the heat can impact significantly on the productivity of some industries which are located in harsh environments. A long-standing dilemma in OHS has been the specification of what constitutes a safe working environment. The current indices used to evaluate the environment are either ...

Hurricane Damage 2018 – Mold, Bacteria, Insects and More
In the aftermath of the devastating hurricane season of 2017 (Harvey, Irma, Jose, Maria and ?), there are many hazards to humans other than just mold. Get ready for a busy 2018 Hurricane Season (Florence!!!). Certainly mold is the most obvious. Storm surge, torrential rains, power outages, and hot humid summer/fall days all serve to create a vast mold incubation condition. Bacteria are also ...
