CHEMICAL AND BIOCHEMICAL PLANTS

The Course of Chemical and Biochemical Plants provides knowledge related to the facilities and unitary operations of the chemical and biochemical industry used in the processes typically used in the control of the cycles of waste materials, including those in the state of the art. In particular, the typical aspects of the process chains related to the treatment of waste streams will be addressed, also in terms of sizing. The second part of the course is dedicated to the reactor part, where the operating logics of the ideal and real reactors and bioreactors applied in the remediation industry will be addressed.

The student will learn the elements for understanding the principles and applications of unit operations in the biochemical industry, the operation of reactors and bioreactors and the sizing of each of these elements, with particular reference to applications in the treatment of solid waste streams, liquid and gaseous.

A basic knowledge of Chemistry, Physics and Mathematics is required.

First part: foundations and unit operations:

- Heat transport: heat generation (boilers and cogeneration systems), heat exchange (exchangers), cooling (evaporative towers)
- Phase separation: sedimentation, membrane systems
- Dehydration: filtration, centrifugation
- Concentration: distillation, concentration, drying
- Absorption

Second part: chemical and biochemical reactor technology

- Reaction velocities and kinetics in biological systems
- Kinetics and biomass growth
- Ideal reactors: batch, CTR, PFR, fed-batch
- Real reactor elements (RTD)
- Applications in biotechnology of bioreactors
