Corrosion is the process of eroding of the top layer of metals as a result of an electrochemical reaction with the environment. When metals are exposed to moisture or wetness, an orangish discolouration known as rust forms on the surface of the metal. This causes deterioration and the gradual destruction of the metal, if not treated effectively. The study of prevention of corrosion and its

Corrosion is the destructive attack of a material by reaction with its environment. The serious consequences of the corrosion process have become a problem of worldwide significance. In addition to our every day encounters with this form of degradation, corrosion causes plant shutdowns, waste of valuable resources, loss or contamination of product, reduction in efficiency, costly maintenance, and

The sudden dilution of a river by heavy rainfall can be a disruptive factor in a water treatment plant. The location of a river water intake should be carefully chosen with this problem in mind. In the operation of a treatment plant, it is common practice to adjust the chemical dosages according to effluent water quality. However, there are many water supplies so variable that it is necessary to

Three-quarters of the surface of the earth is covered with water. While this is an impressive statistic, it is pale beside the spectacular photographs that have come to us from outer space. They reveal a beautiful blue planet bathed in water, partly hidden by a veil of vapor. Life came into being in this water. As living things became more complex and specialized, they left the sea  or the

Biodiesel is an alternative fuel for diesel engines that is gaining attention in the United States after reaching a considerable level of success in Europe. Its primary advantages are that it is one of the most renewable fuels currently available and it is also non-toxic and biodegradable. It can also be used directly in most diesel engines without requiring extensive engine modifications. The

Distillation separates  two  or more liquid components in  a  mixture using the principle of relative volatility or boiling points. The greater the difference in relative volatility the greater the nonlinearity  and  the easier it  is  to separate the mixture using  distillation. The process involves production of vapour by  boiling the

In  the 1950s, chemical engineers might have the impression that  the  ultimate  mission  of  the engineers  was  to transform old-fashioned batch processes into  modern continuous ones (Rippin, 1983). With  such a perspective it is surprising to  find  that, today, fifty years later  a  significant proportion  of &

Biodiesel is a renewable fuel manufactured from vegetable oils, animal fats, and recycledcooking oils. Biodiesel offers many advantages:• It is renewable. • It is energy efficient. • It displaces petroleum derived diesel fuel.• It can be used in most diesel equipment with no or only minor modifications.• It can reduce global warming gas emissions.• It can reduce tailpipe emissions,

All scientific studies involve some aspect of practical work. It is therefore essential to be able to observe and to record information accurately. In the context of environmental analyses, it should be borne in mind that not all practical work is carried out in the laboratory. Indeed it could be argued that the most important aspects of the whole practical programme are done outside the

It is important to have proper subcooling in the vent end of the unit to prevent large amounts of process vapors from going to the vacuum system along with the inerts. Control. It is necessary to have some over-surface and to have a proper baffling to allow for pressure control during process swings, variable leakage of inerts, etc. One designer adds 50% to the

Since before recorded history, we have been using chemical processes to prepare food, ferment grain and grapes for beverages, and refine ores into utensils and weapons. Our ancestors used mostly batch processes because scaleup was not an issue when one just wanted to make products for personal consumption. The throughput for a given equipment size is far superior in continuous reactors, but

The chemical reactor is the heart of any chemical process. Chemical processes turn inexpensive chemicals into valuable ones, and chemical engineers are the only people technically trained to understand and handle them. While separation units are usually the largest components of a chemical process, their purpose is to purify raw materials before they enter the chemical reactor and to purify

The term "fermentation" can be used in its original strict meaning (to produce alcohol from sugar-nothing else) or it can be used more or less broadly. We will use the modern broad definition: From the simplest to the most complex, biological processes may be classed as fermentations, elementary physiological processes, and the action of living entities. Further, fermentations can be divided

There are many ways of classifying chemical reactions. In chemical reactionengineering probably the most useful scheme is the breakdown according tothe number and types of phases involved, the big division being between thehomogeneous and heterogeneous systems. A reaction is homogeneous if it takesplace in one phase alone. A reaction is heterogeneous if it requires the presenceof at least two

Mass Balances (Sinnott, 1985) Material balances are the basis of process design. A material balance taken over the complete process will determine the quantities of raw materials required and products produced. Balances over individual process units set the process stream flows and compositions. A good understanding of material balance calculations is essential in process design. Here the

Every industrial chemical process is designed to produce economically a desiredproduct from a variety of starting materials through a succession of treatmentsteps. Figure 1.1 shows a typical situation. The raw materials undergo a numberof physical treatment steps to put them in the form in which they can be reactedchemically. Then they pass through the reactor. The products of the reactionmust
