Local exhaust ventilation (LEV) systems and integrated collectors were designed and implemented in a mining company in order to control emitted air pollutant from furnaces. The LEV was designed for capture and transition of air pollutants emitted from furnaces to the integrated collectors. The integrated collectors including four high efficiency Stairmand model cyclones for control of particula...

Droplet size is a fundamental parameter for Venturi scrubber performance. For many years, the correlations proposed by Nukiyama and Tanasawa (1938) and Boll et al. (1974) were used for calculating mean droplet size in Venturi scrubbers with limited operating parameters. This study proposes an alternative approach on the basis of artificial neural networks (ANNs) to determine the mean droplet si...

In this article we have made an attempt to survey some results on performance of jet ejector. The literature is also reviewed to pursue further work in this area. Key wordsHEVS, EVS, jet ejector, performance of venture scrubber, characteristics of jet ejector, efficiency

Purpose is to increase uranium content in a PR solution while developing technique varying oxidation-reduction potential of leach with its oxygenation and identify changes the depending upon sulfuric acid concentration as well transportation distance solution. Methods. A laboratory facility, involving tank, pump, Venturi tube, tank install oxygen analyzer, dump has been manufactured under lab c...

The Cape ventilator (Penlon Ltd) still remains one of the most widely used ventilators in intensive therapy units (ITU). However, when low fractional inspired oxygen concentrations (F IO2 ) are prescribed, particularly when associated with low minute volumes (V̇ ), the required supplemental oxygen flow is small. Flows less than 2 litres/min are not uncommon. For example; an F IO2 of 0·35 and a V̇...

There is a vacuum created when water goes past pipe constriction. Air may be pulled into the main flow by drilling hole in near where happens. Venturi aerator an example of application action. A formed at suction holes tube there small difference pressure between input and output sides. To demonstrate link total rate performance, (model 1584) was introduced specific point Biopipe system. For th...
