5. Unreacted ethene is removed in separator A. 6.
An industrial method for the production of ethanol is outlined in the flow diagram.
(a)
The starting materials are ethene and water. Water is a raw material but ethene is not. Why is ethene not a raw material? 1
(b)
(i)
Unreacted ethene is removed in separator A.
Suggest how the separated ethene could be used to increase the efficiency of the overall process.
(ii)
Name the process that takes the place in separator B.
(c)
In the reaction vessel, ethanol is produced in an exothermic reaction.
Name the type of chemical reaction that takes place in the reaction vessel.

6. Lesson 1: Industrial processes
Today we will learn to
Analyse processes to identify where they are economical and efficient.
We will do this by
Revisiting the Haber Process from Nat 5.
We will have succeeded if
We can analyse unseen processes to identify where money, energy or chemicals can be saved.

7. Industrial processes p39
Industrial processes are designed to maximise profit and minimise the impact on the environment.
Factors influencing process design include: availability, sustainability and cost of feedstock(s); opportunities for recycling; energy requirements; marketability of by-products and product yield.
Environmental considerations include: minimising waste; avoiding the use or production of toxic substances; designing products which will biodegrade if appropriate
