All crude oil contains impurities which contribute to corrosion‚ heat exchanger fouling‚ furnace coking‚ catalyst deactivation and product degradation. These contaminants are broadly characterized as salts‚ BS&W‚ solids‚ and metals. The amounts of these impurities vary for different crudes. Generally‚ crude oil

defined somewhat arbitrarily. However‚ most agree that any steel that is alloyed with more than eight percent of its weight being other elements beside iron and carbon‚ is high alloy steel. Low alloy steels are slightly more common. The physical properties of these steels are modified by the other elements‚ to give them greater hardness‚ durability‚ corrosion resistance‚ or toughness as compared to carbon steel. To achieve such properties‚ these alloys often require heat treatment..Example of an alloy

Iron is a vital constituent of plant and animal life‚ and is the key component of haemoglobin. Titanium has a low density‚ good strength‚ is easily fabricated‚ and has excellent corrosion resistance. It burns in air and is the only element that burns in nitrogen. It is marvellous in fireworks. Phosphorous is an essential component of living

The element of Nickel is number 28 which means it has 28 electrons and 28 protons (this is the atomic number). The atomic mass of Nickel is 58.71 g.mol^-1 which means that there are 30.69334 neutrons since you subtract the number of protons from the atomic mass to get the number of neutrons. The electronegativity of Nickel is 1.8 on the Pauling scale; this is the tendency of Nickel to attract a bonding pair of electrons. The density of Nickel is 8.9 g.com^-3 at 20°C and the melting point is 1454

1. INTRODUCTION 1.1 Background The report will mainly focus on the differences between reinforced‚ prestressed and partially stressed concrete. These concrete reinforcing methods differ in the period they have been used. Reinforced concrete was developed by a nursery owner in Paris in 1867‚ Joseph Monier‚ applying it to practical use for the first time (Salmon & Wang‚ 2007). Prestressed concrete’s discovery dates back to the late 1800’s. Freyssinet was one of the first engineers who used
