A wet packed bed scrubber combined with dry oxidation by indirect DBD plasma for conversion of NO to NO2 and wet reduction with two reduction agents of Na2S and Na2SO3 to remove NO2 was developed at room temperature for semiconductor manufacturing industries. The design and operation parameter for the wet scrubber such as gas concentration, liquid to gas ratio, reducing agent concentration, residence...
The site density of catalyst used in the numerical simulation was determined by using the experimental method which obtained the relationship between the temperature and the selective catalytic reduction (SCR) efficiency of NOx. Numerical simulation of the SCR process of NOx in simulating exhaust gas of the marine diesel engine was carried out by using the simplified mechanism of ammonia oxidation...
Diesel Engine Generators (DEGs) are used to generate power but in the process produce emissions of toxic air pollutants (taps). These ‘taps’ include Particulate Matter (PM) and Oxides of Nitrogen (NOx) which are harmful to humans and the environment. This paper has investigated the effect of retrofitting a 15kVA DEG using Retrofitted Diesel Fuel (RDF) and Pure Diesel Fuel (PDF). The data obtained...
Current network architectures are ill-suited to meet today's enterprise and academic requirements. The problem lies in the complexity needed to control and manage the network. This complexity stems from the tight relationship between both data and control plane. Therefore there is a long overdue requirement of innovations in networks. The storage, computing and applications have seen lot of innovations...
Automobile industry is growing towards an electronic engine. With the help of electronic engine, manufacturer can able to provide lot of facilities to customers. This is possible due to high capability of electronic control unit (ECU) and numerous kind of sensors. These sensors are expensive and failure of these sensors during testing of new functionality leads to increase in testing cost. Hence to...
The NOx treatment using streamer discharges generated by nanosecond pulsed powers was studied. The streamer discharges were produced in the treatment reactor by adopting nanosecond pulsed powers. In the previous study, temporal decrease in NO removal ratio was observed as pulse repetition rate increased. This was because the inner wire electrode of coaxial treatment reactor curved during pulse application...
A novel ceria-based amperometric NOx and NH3 sensor was investigated. The sensor consisted of gadolinium-doped ceria electrolyte membrane with (La0.60Sr0.40) (Co0.20Fe0.80)$\text{O}_{3-\delta }$ (LSCF) electrodes applied to opposite sides. The assembly operated in combustion exhaust streams with higher sensitivity to both NOx and NH3, less dependence on oxygen partial pressure, and faster response...
A pilot-scale simultaneous removal of NOx and SOx as a nonthermal plasma and chemical hybrid process (PCHP) is carried out on combustion exhaust gas in a glass manufacturing system. The exhaust gas (12700 m3N/h) is produced by the combustion of fossil fuels and contains both NOx (160 ppm) and SOx (150 ppm). In PCHP, NO is oxidized to water-soluble NO2 through a plasma process using ozone generated...
Recent survey and studies on saving of electricity have concluded that the significant portion of electricity is being wasted due to improper use of electrical appliances mainly in domestic and corporate Sectors. This paper deals with an approximate calculation which shows the effect of saving one unit of electricity per week per customer annually. The losses and efficiency is analysed at transmission...
Air pollutants generated by ships in both gaseous and particulate forms, have a long term effect on the quality of the environment and cause a significant exposure risk to people living in proximities of harbors or in neighboring coastal areas. It was recently estimated, that ships produce at least 15% of the world's NOx (more than all of the world's cars, buses and trucks combined), between 2.5–4%...
The paper describes the testbed to determine the effectiveness of an approach to build network storage using Software-Defined networks (SDN) OpenFlow. It is assumed that main protocol to SAN is iSCSI over local area network. Prototyping tools for managing network resources and data flows on the basis of SDN and testing environments based on Free and Open Source software. We describe experiments with...
Recently, the Future Internet technology becomes a popular research topic. To solve the problems caused in traditional network, most researchers propose various new network architectures. One of the famous architectures is Software-defined network (SDN), which can help users develop their own strategies freely without the limited functions on physical machines provided by specific venders. One of...
This paper presents in the area of software defined networking. Our aim is to identify limitations of current networking technologies and how software-defined networks (SDN) could reduce cost, and improve the performance of campus Networks for their network management. We pursue to identify solutions in this paper to enable possible customers to assess that SDN may be preferable over Current network...
Numerical simulations were conducted for an 800MW ultra-supercritical utility boiler. The influences of over-fire air on distributions of temperature, oxygen concentration and NOx concentration were investigated. The results indicate that the using of OFA made a significant influence on parameters in the primary combustion zone. The temperature, oxygen concentration and NOx concentration all decreased...
A study on the environment impact of civil narrow body turboprop aircraft was performed. Main target of this study is to investigate whether the turboprop is an environmental friendly power substitution for turbofan to power the civil narrow body aircraft through flight performance simulation in typical routes. The study was based on the utilization of three codes, aircraft performance model ‘APM’,...
A simplified kinetic model for thermal DeNOx was developed and verified based on a latest detailed reaction mechanism. The results show the new simplified model improves remarkably comparing with the previous simplified models. Besides, the new simplified model can reproduce the results of the detailed model in plug flow reactor (PFR) reasonably over a wide range of operating conditions, including...
Due to rapid development of Internet, the amount of users around the globe is fast-growing in the past 30 years. It leads to the appearance of many problems, such as lack of IPaddresses, worse quality of service, and so on. In order to resolve these problems, many researchers start to design and implement innovative network architectures, which we call Future Internet. Most Future Internet projects...
Network virtualization gives each "tenant" in a data center its own network topology and control over its traffic flow. Software-defined networking offers a standard interface between controller applications and switch-forwarding tables, and is thus a natural platform for network virtualization. Yet, supporting numerous tenants with different topologies and controller applications raises...
Innovative diesel particulates (PM) collection and NOx reduction technology were developed using plasma combined system over the ears. As for PM control, the EHD-assisted electrostatic precipitator (EHD ESP) to collect low resistive diesel PM and the plasma ESP to collect and incinerate PM were developed.
