Introduction of Chemical Reaction.

After industrial revolution in London (U.K) lot of industrial work established due to which excessive environment. Pollution become a major problem in London so government of United Kingdom appointed to check and gives suggestion to reduce the pollution emitted by the factories.
There he absorbed some common factor/operation in various factories like following of fluid, exchange of heat, exchange of mass, he prepared 12 lectures on common operation and started teaching them in United State/Kingdom.
After that come to known that these lecture and that unit operation in 1957 there was a conference in Amsterdam where the little of conference was Chemical Reaction Engineering and they wanted to concentrate only on reaction .

J.C Vlagter gave this name CRE in 1958 in Amsterdam
When we apply all Engineering principle to Chemical Reaction Engineering.

Application of CRE.
● Waste Treatment.
● Living System.
● Manufacturing of Pharmaceutical.
● Manufacturing of Chemical.
● Modeling of Smoke.
● Petroleum Product.
● Food Industry.
● Print Industry.
● Water Treatment.
● Textile Industry.
● Nano Particle etc.

Defination of CRE. The study of CRE Combines the study of Chemical kinematics with reactor in which reaction occur.
Chemical Reaction. A chemical reaction takes place when a number of molecular of one or more chemical species have lost/loose their indentation and assume a new form by a change in the kind or number of atoms in the compound or by change in structure and configuration these atoms.

There are three basic ways in which a species many loose it's chemical identities.
1. Decomposition.
2. Combination.
3. Isomerization (Change in Structure)

Rate of reaction:- It is represented by - rate of reaction tells us how fast the number of molecules of one chemical species are being to forms another chemical reaction.

Isomerization or Isomerization:- Isomerization is the process by which one molecules which transformed into another atoms but the atoms have different arrangement. Ex. A-B-C - B-A-C (these related molecules know as isomer)
Rate of Reaction:- The rate of reaction (-ra) is the number of moles of a reacting (disappearance) per unit time per unit volume.
-ra unit :- mol/& litre

Properties of Fluids

Image
We know about fluid and students every fluid(liquids, vapours, gases) has definite properties which help us to describe its physical condition. Such properties are called properties of fluid. It also  helps us to analysis fluid flow problem. PROPERTIES OF FLUIDS There are main properties of fluids following :- 1. Density or Mass Density:- It is the ratio of mass of a fluid to its volume. It is de noted by ρ( ro ).     Mass Density,.   p = Mass of fluid/volume of fluid                                  =m/v SI Unit of density or Mass Density is Kg/cubic meter.   The density of water is 1000kg/cubic meter or 1 gm/cubic centimeter. 2. Specific Weight:- It is defined as the ratio of the weight of a fluid to its volume. It is denoted by 'w' and is also called weight density.  ...

Introduction of Water, impact of water pollution, uses of water and impurities in water.

Image
                                  WATER 1. Water is an important gift of nature for all the living things. As it is used in all types of metabolic activities and house hold works. It may be defined as “Clear, transparent, odourless and tasteless liquid. Chemically it is made up of two atoms of Hydrogen and one atom of Oxygen.      2. In day to day life, required potable water means should be tasteful, aesthetically pure and wholesome. But due to presence of some chemicals, biological and microbes it’s become unfit for drinking and for other uses.

What is Petroleum and origin of Petroleum?

Image
  Petro leum: we know that liquid fuels are used extensively these days in industrial and domestic areas. Today we will discuss about liquids fuel and we hear about Petroleum, which is a largest source of liquid fuel.             The Petroleum means rock oil or it is also known as mineral oils. Crude oil and petroleum is a basic raw material for refining industries.it occurs in the earth crust mostly in sedimentary rocks in all possible state(gas, liquid and solid). It is dark colour viscous liquid colour varies from light brown to dark brown.petroleum is a mixture of various hydrocarbons mainly ' PONA' .
