Emission Control Techniques
1. INTRODUCTION
The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons, carbon monoxide and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere from the tail pipe. There are also hydrocarbons emitted as a result of vaporization of gasoline and from the crankcase of the automobile. The clean air act of 1977 set limits as to the amount of each of these pollutants that could be emitted from an ....etc

THE IMPACT OF TRANSPORTATION CONTROL MEASURES ON EMISSION CONTROL DURING THE OLYMPIC GAMES IN BEIJING

1. INTRODUCTION
1.1 GENERAL

Emissions from vehicles come from the by-products of the combustion process which takes place inside the vehicle when it moves. In addition to this, volatile organic compounds (VOC) also escape through fuel evaporation. As vehicle exhaust systems have improved, evaporative emissions have become a larger component of total vehicle VOC emissions

The combustion process results in emissions ....etc

download ppt on sulphur infiltrated concrete

Abstract

Sulfur concrete is a composite construction material, composed mainly of sulfur and aggregate (generally a coarse aggregate made of gravel or crushed rocks and a fine aggregate such as sand). Cement and water, important compounds in normal concrete, are not part of sulfur concrete. The concrete is heated above the melting point of sulfur ca. 140 C. After cooling the concrete reaches a high strength, not needing a prolonged curing like normal concrete. Sulfur concrete is resistant to some ....etc

In sulphur hexa fluoride ckt breaker, SF6 gas is used as the arc quenching medium. The SF6 is an electronegative gas and has a strong tendency to absorb free electron. The contacts of the breaker are opened. In a high pressure flow of SF6 gas an arc is struck between them. The conducting free electrons in the arc are rapidly captured by a gas to from relatively immobile ion. This loss of conducting electrons in the arc is quickly builds up enough insulation strength to extinguish the arc. The SF6 ckt breakers have been fou ....etc
