Aspen simulation needed.

I have a feed stock af 21000 lb/hr acids mix in a water solution. I would like to separate each of the components. Need to find out sizing of all the equipment used, pressures, temperatures, flow to each unit and from. energy, power all the Aspen can offer.
The feed composition is:
Lactic acid - 12000 lb/hr
Levulinic acid - 320 lb/hr
Acetic acid - 1800 lb/hr
Formic acid - 1400 lb/hr
Water - 4700 lb/hr
Total feed - about 21000 lb/hr
This is the mix and i would like to separate each of the acids the most efficient way posible.
