Subject aims expressed by acquired skills and competences
Students will deepen their knowledge of process engineering in the area of diffusion separation processes and special type of chemical reactors. They will be able to apply theoretical knowledge to design operation units with regards of operational limits of equipment.
Students will be able to orient in the project documentation and to draw PFD and PID scheme. Furthermore, they will be able to design separate technological units not only in terms of material and energy flows, but also in terms of investment and operating costs.
