Beschreibung:
Part I : Physical Chemistry and Thermodynamics

1.      Introduction: Overview, achieving high pressure, range of parameters.

2.       Influence of pressure on properties of fluids: P,v,T-behaviour, enthalpy, internal energy,     entropy, heat capacity, viscosity, thermal conductivity, diffusion coefficients, interfacial tension.

3.      Influence of pressure on heterogeneous equilibria: Phenomenology of phase equilibria

4.      Overview on calculation methods for (high pressure) phase equilibria).
Influence of pressure on transport processes, heat and mass transfer.

Part II : High Pressure Processes

5.      Separation processes at elevated pressures: Absorption, adsorption (pressure swing adsorption), distillation (distillation of air), condensation (liquefaction of gases)

6.      Supercritical fluids as solvents: Gas extraction, cleaning, solvents in reacting systems, dyeing, impregnation, particle formation (formulation)

7.      Reactions at elevated pressures. Influence of elevated pressure on biochemical systems: Resistance against pressure

Part III :  Industrial production

8.      Reaction : Haber-Bosch-process, methanol-synthesis, polymerizations; Hydrations, pyrolysis, hydrocracking; Wet air oxidation, supercritical water oxidation (SCWO)

9.      Separation : Linde Process, De-Caffeination, Petrol and Bio-Refinery

10.  Industrial High Pressure Applications in Biofuel and Biodiesel Production

11.  Sterilization and Enzyme Catalysis

12.  Solids handling in high pressure processes, feeding and removal of solids, transport within the reactor.

13.   Supercritical fluids for materials processing.

14.  Cost Engineering
