What Is Heat Transfer

Heat transfer is considered as one of the most basic discipline of chemical engineering & technology. It generally concerns with generation, consumption and conversion of heat energy in the system. Heat transfer; it self plays a very important role in process industries, and it is always better for the process industries, to optimize their heat transfer processes (may include furnaces, evaporators, distillation units, dryers, reaction vessels etc) by the selection of proper heat exchangers, preventing heat losses and controlling the...

What Are Fertilizers

Fertilizer industry is one of the most important industries. To study that what are fertilizers, the basics of chemical engineering are required. Types of fertilizer depend on the thorough study of the nature of the soil, and the type of the plants. So first, it is important to review the plants physiology and needs then we can move on to what are fertilizers. Plants have the natural ability to convert carbon dioxide from the atmosphere and inorganic components of the earth directly into the fats, proteins and high energy carbohydrates. So the...

Types of catalysis

In my last post, I have discussed about the general catalysis phenomena, and its most basic types. But the homogeneous and heterogeneous catalysis are not the only types of the catalysis. The chemical engineer also classifies catalysis on the basis of the nature of species responsible for the catalytic activity. These types are mostly inter-related with other types of the same nature. E.g. molecular catalysts can be used as homogeneous, as well as heterogeneous catalysts, Surface catalysts are heterogeneous catalysts etc. Some of the types are:1)...

Catalysis

Catalysis is the key to optimized and efficient process engineering. Catalysis is the major problem for the chemical engineer while understanding the basic chemical reaction engineering. Catalysis is used in most of the industrial and biological processes, and the products of these processes include food, drugs, clothing, plastics, fuels or detergents.To understand the phenomena of the catalysis, a chemical engineer must understand that what is catalyst? Catalyst is the substance, which changes the rate of the chemical reaction, with out being...

Rheology

Rheology is the study of deformation and flow behavior of materials. Rheology is generally associated with the behavior of the fluids, but the semi-solids materials (under specific conditions) some times also possess the rheological properties.Rheology normally accounts for the flow of unusual materials, generally non-Newtonian fluids, as rheological properties are the parameters in any quantitative functional relation between the stress and strain.And as we have already discussed that the Newtonian fluids have the linear relationship between the...

types of fluid

Fluid mechanics is one of the major sciences involved in chemical engineering, so a chemical engineer is mostly interested in many aspects of the problems involved in the fluid flow. To understand the fluid mechanics, a chemical engineer must have to understand that what is fluid, and the types of the fluid. The simplest definition of the fluid is that “Any substance which can flow under pressure is fluid”. Fluid can also be defined as “any substance that has no fixed structure, shape or size, and yields easily to the external pressure”. There...

Bleaching agents

Bleaching agents are the materials, which are used for the lightening, decolorizing or whitening of a substrate by the chemical reactions.  The color producing materials are generally organic in nature, containing“chromophores” (Chromophore is that portion of molecule that absorbs light photons)..The bleaching action is normally based on the oxidation or reduction processes that degrade the color systems. Chemical bleaches works in one of two ways:.Oxidizing bleach breaks the chemical bonds that make up the chromophores. Thus the molecule...

Air Pollution because of process industries

Being a chemical engineer, you must be aware of the hazards and outcomes of the unmanaged and poorly handled processes in process industries. One of the major disadvantages of these poorly handled chemical processes is the Air Pollution. However energy generation is also considered as the major source of the air pollution. In air pollution, the air is contaminated with several unwanted substances, which produces direct measurable effect on receptors (receptor may be humans, animals, plants or environment). This situation becomes more dangerous...

Chloro-floro carbons are member of halo alkanes ( or alkyl halides), which belongs to the group of chemical compounds , derived from alkanes, containing one or more halogens. these are generally used as refrigerants, solvents, fire extiguishants, and as pharmaceuticals. Many haloalkanes, including chloro-floro carbons are considered as the serious pollutants and toxins to the environment. In actual, CFC's are the hydrocarbons, fully halogenated with chlorine and fluorine, and in the presence of sun light, the chloro-floro carbon molecule breaks...

coal, expected alternative fuel in future

Although, it is not a newer trend, to use coal as a fuel. There are many industries, which are using several technologies like gasification or the liquification of coal, to fulfill their fuel or energy needs. However, there are several environmental hazards in handling of coal , because of the high ash , or sulfur content of the coal. The experts are trying to find the safe handling procedures for the safe use of this black gold. Recently, an Australian based team of researchers, including CSIRO and the university of new castle, has developed a...

Heat transfer is considered as the basics of chemical engineering, and most important heat transfer equipment is the heat exchanger. A chemical engineer knows it very well that what is heat exchanger. Heat exchanger is the equipment used for effective transfer of heat between two fluids. These fluids are separated by means of solid wall, to avoid their mixing. The heat exchangers are the widely used equipments in chemical and process industries, So why a chemical engineer must have firm grip on heat exchangers designs, and their working. Most common...

Prepare stearic acid at home

Stearic acid is a usually a most common chemical, used in process industries , and it is quite expensive too. So it is not a difficult task for a a chemical engineer to prepare stearic acid locally at a very cheap cost. Just buy a natural soap bar ( try to get the most cheapest among all), this reaction will only work with the natural soap bar, so try to do the reaction on a little piece of soap initially. Dissolve the natural soap bar in hot water completely. Add food vinegar (but the food vinegar is needed in higher volume, so you can add any...
