Summary

We have in the previous chapters identified different types of the raw materials and products that can ensure a transformation from a petroleum-based to a bio-based society. We have discussed how raw materials can be converted to the required end-products. Before we end up with the final purified product, we still need a number of separation and purification steps. We need to select proper separation methods to reduce the cost of the process and ensure the required quality of our product. In this chapter, we will define the key parameters that are necessary to know to identify the relevant processes. This includes feed concentration, particle characteristics, and solvent properties. The chapter will introduce the existing methods for product purification and introduce guidelines for the selection of the best technologies for the separation and purification processes.
