Coulometry has been established as an important and reliable method for the determination of acidic compounds. The analytical method and simple apparatus described here arc applied to the precise and accurate determination of sulfur dioxide in nitrogen, specifically in compressed gas cylinders at nominal concentrations of 50 and 100 µmol/mol (ppm). This method is constant current coulometry whe...

Slit,?In 1899, with reference to plague prevention as then understood, I made experiments as to disinfection of floors " by flaming." Cylinders of compressed petroleum gas were employed, and, with the aid of the late Mr. Phipps of the Loco. Dept., Madras Railway, and Messrs. Mansfield and Sons (now of Calcutta), at the end of flexible tubes?long enough to allow the adjunct apparatus to be place...

Safety distance has already been a main measurement for the hazard control of chemical installations interpreted to mean providing space between the hazardous installation and different types of targets. But, the problem is how to determine the enough space. This study considers the application of quantitative risk assessment to evaluating a compressed natural gas station site and to identi...

OBJECTIVE Laparoscopic procedures utilize a pneumoperitoneum to distend and separate the abdominal wall from the intra-abdominal structures. Carbon dioxide is commonly used for this purpose, although this study is inclusive of any gas used for abdominal distention. The gas is delivered from cylinders through a gas insufflation delivery system. The purpose of this study is to determine if laparo...

Compressed biomethane gas (CBG) is an interesting alternative fuel that can be used to solve fossil crisis problems. Nevertheless, it concerned about engine performance and exhaust emission. In additions, CBG produced from agricultural harvesting residues the food industry a good opportunity for utilizing biogas as vehicle fuel. The aims of this research are comparative analysis emission on com...

Background: One of the substances with a high potential of damaging that nowadays is used widely in industry and human environment is LPG gas cylinders. Aim: The purpose of this study is modeling the consequences of gas leakage in domestic cylinders containing LPG (Liquefied petroleum gas). Subjects and Methods: The factors affecting discharging and emissions of LPG gas in 26, 60, 78 and 107 li...
