throughout the visible spectrum. It is also one of the most efficient hardeners of platinum and palladium. It is alloyed with these metals to make electrical contacts for severe wear resistance and some jewelry. These alloys are also used to improve the corrosion resistance in titanium. It is a versatile catalyst used to remove H2S from oil refineries and other industrial processes‚ to produce ammonia from natural gas‚ and to produce acetic acid from methanol. Ruthenium has no known biological role‚ but ruthenium(IV)

dissolved gases from the feedwater to steam-generating boilers. In particular‚ dissolved oxygen in boiler feedwaters will cause serious corrosion damage in steam systems by attaching to the walls of metal piping and other metallic equipment and forming oxides (rust). Dissolved carbon dioxide combines with water to form carbonic acid that causes further corrosion. Most deaerators are designed to remove oxygen down to levels of 7 ppb by weight (0.005 cm³/L) or less as well as essentially eliminating

The shape of the long profile (a slice through the river from source to mouth) shows how the rivers gradient‚ height‚ energy and load changes due to erosion processes such as abrasion‚ cavitation‚ attrition‚ hydraulic action and corrosion as well as how the rivers deposition rates fluxuate. The source of the mouth is the part of the drainage basin where the river starts. It is usually high above base level‚ such as a mountain‚ and has a very steep gradient. As a river flows down

Plastics are considered ideal materials of construction for cooling towers because they are durable and resist corrosion. But factory construction of plastic towers has until now been limited to a capacity of about a couple hundred cooling tons – too small for many industrial applications‚ says John Flaherty‚ president of Delta Cooling Towers‚ Inc.
