Gas Cleaning System with a Pre-Unloading Flow

Isoflurane in a circle system with low gas flow.

Isoflurane was administered from a Goldman vaporizer to a circle breathing system with low fresh gas flows. The uptake and vapour concentration of isoflurane were compared in two groups of spontaneously breathing patients receiving oxygen alone (n = 19), or nitrous oxide and oxygen (n = 30). Anaesthesia was maintained successfully in all patients. The authors believe this to be a safe and econo...

Flow characteristics of gas-liquid-particle mixing in a gas-stirred ladle system with throughflow

An experimental study is performed on air-liquid-particle mixing, resulting from an air-particle mixture injected into a liquid flowing through a slender ladle. Flow visualization combined with image processing is employed to investigate the bubble and particle behavior at the nozzle outlet. Effort is directed to particle discrimination in both the liquid and the bubbles to determine particle d...

The Most Cost Effective Gas Cleaning Device in Steel Industry with Industrial Ecology Approach

Industrial growth and environmental damages, as two important indicators in sustainable development are followed by steel industry. This article leads industries to green industry. In this case, energy, material, capital consumption and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally sui...

Gas cleaning in flue gas from combustion of biomass

A Study of Flow and Mixing in Bubbly Gas-Liquid Pipe Flow Generated by a Grid

The spreading of a tracer in a bubbly two-phase grid-generated turbulent flow system is studied. In this work both particle image velocimetry (PIV) and planer laser-induced <span style="font-size: 10pt...
