Industrial Processes

Question 1

Factors to consider when designing an industrial process

Answer 1

cost of raw materials 
availability of raw materials 
energy costs 
rate 
equilibrium position

Question 2

Cost of raw materials

Answer 2

cost of refining purifying extracting or even making the starting material affects whether process is economically viable
if it is too expensive to source - may not be profitable

Question 3

Availability of raw materials

Answer 3

non-renewable - eventually will run off

best to use renewable or common rather than in short supply

Question 4

Energy costs

Answer 4

high temps and high pressures are expensive to maintain

Question 5

Rate

Answer 5

product made at a reasonable rate may compromise yield

Question 6

Equilibrium position

Answer 6

some industrial reactions are reversible
being able to control equilibrium position to maximise product made increases profits
if equilibrium lies to the LEFT then reaction has low yield
this means not much of the reactants are made into products
