• Used to simulate the process prior to scaling up

• Has difference purpose compared to scale-down

• Usually does not use the data from the industrial-scaled process

Which of the following is NOT the goals for the Scale-down process?

• To investigate the problem in an existing plant

• To up-scale the process from lab-scaled to the real machine in the plant
