In reality all chemical reactions are reversible in nature. Moreover, final conversion of raw materials depends on the ratio of forward and backward reaction rates. During the reaction, at equilibrium state concentrations of reactants and products don’t change. Also, for some reactions when forward reaction is too high in comparison with reverse reaction rate and […]

The Chemical Engineer is a versatile engineer among all other type of engineers. They design and operate the chemical plants, which manufacture valuable and useful products from low value and waste materials. Moreover, a chemical engineer is responsible for the environment sustainability and operational safety also. A chemical engineering graduate starts his or her carrier

What Is Chemical Engineering? Chemical engineering is the branch of engineering. This is related with process design, construction and operation of the chemical plants. Major processes involved in chemical plants for example are Reaction, Absorption, Distillation, Extraction, Filtration and Drying etc. Chemical engineering is all about transforming cheaper or waste raw materials into valuable and useful products.

In chemical process industries distillation columns are widely used unit operation. And, based on the production capacities this can be batch distillation or continuous distillation process. What is Distillation Column? Distillation column separate a feed stream having multiple components into two different streams based on the difference in boiling points. So, higher the boiling point

In chemical engineering, model equation enable us to understand the behavior of the process. Therefore, using mathematical models we can run the process virtually and get optimum operating process parameters. Afterwards, we can use these optimized parameters for real life process. System Description We have an agitated reactor having volume V, in which two liquid

Pumps are just like a heart of any chemical plant, which are continuously running for feeding, circulating or transferring fluid from one point to another point inside a plant. For trouble free operation, appropriate selection of pumps is very important. For this you need to know the nature and characteristics of the service fluid .

Background In real life as a process engineer we face situations where we need to calculate the velocity distribution and film thickness of falling film outside of a circular tube. For example, falling film evaporator, falling film gas absorption, where a viscous fluid flows upwards through a small circular tube and after that it overflow

Background As a process engineers many time we are required to prepare a mathematical model for non-reacting liquid tank or vessel having various shape (cylindrical, conical, wedge shaped, etc.). So, we are going to develop the same, let’s begun with a vertical cylindrical vessel shown in below figure. Consider following parameters for this vessel Input

In chemical industries we apply insulation to reduce heat losses to the surrounding, which is the cost to product. You can see there are two components for total cost in insulation work. First is the cost of installation of the insulation. And, second is loss of profit due to energy loss from the insulation. Therefore,

Cooling towers are very important part of any chemical process industries. It supplies cooling water to Condensers, Coolers and Jackets of Reactors / Vessels to remove the heat. So, fundamentally cooling towers are direct contact type heat exchangers. In which hot water from plant returns to tower and comes in contact with the air. And,
