TYPES OF BIOREACTORS

STIRRED TANK FERMENTER Microbial fermentations received prominence during 1940’s namely for the production of life saving antibiotics. Stirred tank reactor…

STATE OF EQUILIBRIUM

In a reversible reaction, both forward and backward reactions take place simultaneously. When the rate of the forward reaction becomes…

RATE OF A CHEMICAL REACTION

So far we discussed various types of chemical reactions and the nature of the reactants and products. Let us consider…

Classification based on the direction of the reaction

You know that innumerable changes occur every day around us. Are all they permanent? For example, liquid water freezes into…

Classification based on the nature of rearrangements of atoms

So far you studied about a chemical reaction and how it can be described as a chemical equation. A large…

Plug Flow Reactors (PFRs)

General Mole Balance Equation At steady state- Differentiating, that gives- For single reactions in terms of conversion- The differential form…

PFR vs. CSTR: Size and Selectivity

Continuous Stirred Tank Reactors (CSTRs)

General Mole Balance Equation Reactors in Series Given rA = f(X) the Levenspiel Plot can be used to find the reactor volume…

Recycle reactors

Continuous-Flow Reactors

Continuous flow reactors are almost always operated at steady state. We will consider three types: the continuous-stirred tank reactor (CSTR), the plug flow…

Continuous reactor

Continuous reactors (alternatively referred to as flow reactors) carry material as a flowing stream. Reactants are continuously fed into the reactor and emerge as…
