In almost every chemical plant we use distillation column to separate the components based on their boiling point difference. Also, we know distillation columns are the major consumers of steam & cooling water utilities. Therefore, to increase the contribution margin of the product it is necessary to minimize energy requirement in distillation process. We can […]

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

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

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

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,
