Chemical Reaction Engineering - Lecture # 1 - Introduction, Applications, Scope, Rate of Reaction

Hello everyone. Welcome back to the Aspentech Channel. From now onwards, we are shifting toward the theoretical aspects of the simulated equipment, and in this regard, we are starting with Chemical Reaction Engineering. 1st lecture on CRE is presented here in which the following aspects are covered:
i. Introduction to Chemical Reaction Engineering
ii. Pillars of Chemical Reaction Engineering
iii. CRE in Industry
iv. How the Chemical Engineer is different from others?
v. Applications of Chemical Reaction Engineering
vi. Chapter # 1: Mole Balance
a. Chemical Specie and Chemical Identity
b. Rate of Reaction

Thank you very much for your videos! I am currently looking for the reaction rate of dehydrogenation of isopropanol to simulate it in Aspen. Do you know a good database where i could get such infos from? Kind regards

[@ahsanwaqar9951]

Thank you Sir for the informative video. Can you differentiate between the rate of disappearance of A (-rA) and change in concentration of reactant A over time dCA/t. How are these different?

[@aspenchemchannel]

Glad to hear from your side. -rA represents the rate of reaction/disappearance of A per unit volume, while dCa/dt is simply a mole balance valid for only constant volume batch reactors. dCa/dt doesn't apply to CSTR or other reactors. I hope that clarifies! 😊

sir,
It would be kind if you make video on biomass gasification model using aspen plus.

[@aspenchemchannel]

Sure. After a few lectures on CRE, these are in the preparatory/uploading phase.

Thanks for the video.. I want to ask a question, in Test, we dont have the value of rate of disppearance of reactant B. So how can we calculate the answers?

[@aspenchemchannel]

If you know -rA, then by observing the stoichiometry coefficient, -rB can be found. For example, if A + 2B is in the equation, then, -rA/1 = -rB/2 and then -rB = 2*-rA. We will study it in Chapter 3 as well.
