What is this course about?

Liquid reactant

Cooling water

Cooling water

Liquid product

Reactor

How to get

flow rates

compositions

(temperatures: CPP2)

Complications

Chemical plants often have many inter-connected equipments!

D r . Y e o h H a k K o o n 2 0 1 5 8

Recycle Purge

Bypass

It is not so clear-cut

to get information for

each stream!

At the end of this course, you should be able to tackle such systems!

Course outcomes

At the end of the course, you are able to: Identify unit operations involved in a process, draw process flowcharts, and develop relationships between process variables

Perform simple degree-of-freedom analysis to identify the number of unknowns relating to mass, mass flow rate, composition, and develop the linearly independent mass balances needed to determine unknown quantities

Solve for the unknown variables using fundamental laws, empirical relationships, and available data

Solve material balances on chemical process systems

D r . Y e o h H a k K o o n 2 0 1 5 9

These are what you will

be assessed for!
