Doha west power Generation and Water Distillation Station is one of the main base load plants of the country governed by the ministry of electricity and water‚ government of Kuwait. This power station is situated in Doha‚ located approx. 15 km to the west of Kuwait city. This power station is composed of eight power generating units of 300 M.W. capacity each and 16 water distillation units of 6/6.2 million imperial gallons per day capacity each. In all‚ power station is capable of generating 2400

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

Origins of the Name The word‚ Aluminium originates from the ancient Latin word for alum‚ alumen‚ which is potassium aluminum sulfate‚ meaning “bitter salt”. We pronounce the element of aluminium’s name as follows‚ al-yuh-min-ee-uhm‚ which conforms to the IUPAC pronunciation of the word‚ with the regular ‘ium’ ending of majority of the elements of the periodic table. The History Aluminium was first discovered in 1825‚ by early discoverer‚ Hans Christian Oersted in Denmark. Before this time‚ alum

chemical attack at temperatures below 150 C. Tantalum is virtually resistant to corrosion due to an oxide film on its surface. Applications Tantalum finds use in four areas: high-temperature applications‚ such as aircraft engines; electrical devices‚ such as capacitors; sirurgical impants and handling corrosive chemicals. It is rarely used as an alloying agent because it tends to make metals brittle. Tantalum resist corrosion and is almost impervious to chemical attack‚ for this reason it has been employed

accidents. Of these three‚ surface degradation of machine parts results in the machine’s loss of usefulness in the vast majority of cases. Surface degradation is comprised mainly of corrosion and mechanical wear. Corrosion of machine parts is quite common‚ especially for those with water-contamination issues. Water not only rusts iron surfaces‚ but it can also increase the oil’s oxidation rate‚ leading to an acidic environment within the component. Acids can also be formed as byproducts of reactions between

Silicon-based polishing pads or a diamond solution can be used in the polishing

What causes ASS? ASS are any material or sediment that contains iron sulfides that‚ when disturbed or drained‚ forms sulfuric acid. In most cases‚ the iron sulfide present is pyrite (FeS2‚ also known as Iron (IV) Sulfide). This pyrite is very reactive. It is usually the smaller crystals of pyrite found in ASS. The pyrite reacts with oxygen to create sulphuric acid (therefore disturbing the soil creates the acid‚ as the pyrite is exposed to the air). The smaller pyrite framboids (raspberry shaped

is heated at certain temperature‚ then it is slowly cooled. First‚ the steel is heated at a temperature of about 16000F (8710C) for a certain amount of time (“Annealing of Tool Steel”). During annealing‚ ferrite‚ which is pure iron‚ turns into austenite‚ another type of iron (“Full Annealing”). The heating time is dependent upon the size of the specimen to be annealed‚ which is about two hours per inch thickness of the specimen (“Annealing of Tool Steel”). After the metal is heated for the desired
