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...

Liquefied petroleum gas (LPG) cylinder is a type of pressure vessel that used to store and transport liquefied gases. In this study, S460MC steel with thickness 1.50 mm submerged arc welding method were in the manufacturing LPG cylinders. Selection consumables (wire, flux) optimization parameters (current, voltage, travel speed) are primary focus study. Selected have been verified as result vis...

PURPOSE To examine the association between household use of biomass fuels for cooking and birth weight. METHODS Analysis is based on 3559 childbirths in the 5 years preceding the 1999 Zimbabwe Demographic and Health Survey. Birth weights, recorded by trained professionals at local health clinics, were derived from health cards at home or from mother's recall. Multiple regression method was us...

The inducer is a very small booster pump, lifting the suction pressure to a sufficient level for the main conventional impeller. By adding the inducer to high speed centrifugal pumps, NPSHr can be reduced to a great extent. Liquid with high gas content can be pumped successfully with inducer equipped pumps. Even low NPSHr allows a smaller, higher speed low horsepower pump, saving energy and cap...

Air-fuel ratio control in gasoline engines has so far relied upon the fact that the stoichiometric air-fuel ratio of gasoline is an identified constant, largely thanks to its consistent chemical composition. In the case of Liquefied Petroleum Gas (LPG), chemical composition is subject to high variability due to geological and economic factors, amongst others. The implication of this variability...

To characterize the toxicological hazards of petroleum gases, 90-day inhalation toxicity (Organization for Economic Cooperation and Development [OECD] 413) and developmental toxicity (OECD 414) tests were conducted with liquefied propane gas (LPG) at concentrations of 1000, 5000, or 10,000 ppm. A micronucleus test (OECD 474) of LPG was also conducted. No systemic or developmental effects were o...

Use of liquefied petroleum gas (LPG) in compression-ignition (C-I) engines has always been considered important in the diesel engineering field. This is due to its easy accessibility and good combustion characteristics. In this paper the application of LPG fuel along with diesel oil in a direct- injection automotive diesel engine is experimentally investigated. In order to convert the pure dies...

Abstract We explore the relationship between Liquified Natural Gas (LNG) and Petroleum (LPG) carrier freight rates global geopolitical risk, while also controlling for macro environment. Our results show that a shock in risk significantly increases cost of spot charter both LNG LPG carriers, with impact reaching around 25% former 18% latter. bear significant implications companies countries inv...
