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

a) Low pressure water mist system: where
the pressure encountered by the system is
175 psi or less, the same pressure range
used for most of standard water spray
system
b) Intermediate

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

OIL AND GAS CONSERVATION AND ITS RELEVANCE



INTRODUCTION: -

Oil and gas conservation means their better and more efficient use with regard to economic, social or environmental costs and benefits, resulting in attainment of higher energy use efficiencies, minimization of wasteful practices and wastage and protection of the environment. Petroleum is the primary energy source in India and a preferred swing fuel. Its consumption has been increasing at a very steep rate.

Touch screen operated industrial oil dispensing system (OIL SCADA)
The project aims in designing a system which is capable of dispensing required
amount of oil given by the user through touch screen. This system also provides the
security of accessing through password enabled feature. Liquid dispensing systems are
quite commonly found in our daily life in different places like offices, Bus stands,
Railway stations, Petrol pumps. Here we are going to present modern era liquid
dispensing system which is meant to be operated with touch screen inte ....etc
