Effect of H2S on metal dusting of iron - Schneider - 2003

Abstract. A review is given on the effect of H 2 S on metal dusting of iron which has been studied by gas carburisation in CO-H 2-H 2 O-H 2 S and CH 4-H 2-H 2 S mixtures at 500 and 700°C.. The presence of H 2 S in carburising gas atmospheres leads to sulphur adsorption on the iron surface, which retards carbon transfer. Segregation experiments and surface analyses have shown that sulphur

Petroleum - Wikipedia

Petroleum is used mostly, by volume, for refining into fuel oil and gasoline, both important "primary energy" sources. 84 percent by volume of the hydrocarbons present in petroleum is converted into energy-rich fuels (petroleum-based fuels), including gasoline, diesel, jet, heating, and other fuel oils, and liquefied petroleum gas.

Product Information Sheet

Explosion: Hydrogen and oxygen gases are produced during normal battery operation and charging. These gases escape through the battery vents and may form an explosive atmosphere around the battery if ventilation is poor. Avoid open flame, sparks and other ignition sources in areas where batteries are used or stored.

An alternative to SF6 in electrical switchgear - EE Publishers

Due to its excellent properties for electric insulation and arc interruption, SF 6 enables safe and reliable operations while making it possible to reduce the size of switchgear installations significantly. However, SF6 is a greenhouse gas and the life-cycle management costs incurred when handling SF6, particularly when the decommissioning of ageing substations is on the increase.
