Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because

an applied stress. Both gases and liquids‚ therefore‚ are fluids‚ which can be exemplified by water. As far as an engineer is concerned‚ liquid water and gaseous water‚ or steam‚ function as a fluid. At the beginning of the 20th century‚ two types of engines were common: bladed turbines‚ driven by either moving water or steam generated from heated water‚ and piston engines‚ driven by gases produced during the combustion of gasoline. The former is a type of rotary engine‚ the latter a type of reciprocating

breakthrough in technology. Cugnot also has another title to his name: the first person ever to be involved in a motor vehicle accident in 1770. He crashed his second invention of the steam-powered tricycle‚ which could carry 4 passengers. In 1789‚ the American Oliver Evans was granted the first US patent for a steam-powered land vehicle thus introduced America to a new mode of transportation. In 1807‚ another breakthrough was brought about. A Swiss man named Francois Isaac de Rivaz invented the

Introduction The water system in any pharmaceutical organization is of vital importance. It is widely used in pharmaceuticals and related industries. Water used in process and in cleaning must be pure and free from microbial and chemical impurities. Laboratories need pure water free of foreign substances‚ which could potentially affect the outcome of analyses‚ and the pharmaceutical industry needs pure water for a variety of purposes – everything from cleaning to the use of pure water as an ingredient

utilize the force that can be imparted by a jet of fluid on a surface diverting the flow. For example‚ the pelt on wheel has been used to make flour. Further more‚ the impulse turbine is still used in the first and sometimes in the second stages of steam turbine. Firemen make use of the kinetic energy stored in a jet to deliver water above the level in the nozzle to extinguish fires in high-rise buildings. Fluid jets are also used in industry for cutting metals and debarring. Many other applications

INTRODUCTION 1. INTRODUCTION The copolymerization of ethylene with 1‚ 3-butadiene to give crystalline‚ homopolymer-free‚ high molecular weight‚ substantially linear copolymer is described. Butadiene polymerizes almost exclusively in a trans-1‚ 4 structure‚ ranging in content from zero to 50 mole-%. At relatively low content of butadiene monomeric units (≤30 mole-%) X-ray crystallinity is of polyethylene type with a slight variation of the structural parameters. At higher levels of
