In this thesis, we discuss the design of a mobile stainless steel passivation process system.
The system is designed for pharmaceutical use and also for the requirements of clean rooms,
where all materials must be stainless and must not leave any traces on the contact surfaces.
An overview of the standards is carried out and the pre-treatment and passivation process is
described. Parameters for the preparation of the necessary solutions are given, suitable media
are reviewed, and process and process parameters are discussed. A process system for the
passivation of stainless steel in a 3D environment is designed based on standards,
recommendations and examples of good practices, as well as process schemes and
descriptions of operating cycles. The system contains a container for preparing solutions, a
pump, heaters, control valves and measuring equipment for monitoring temperature,
medium conductivity and pH. The selected equipment is supported by calculations, and the
other construction materials are selected according to their chemical resistance. A cost
estimate for the production of the process system is also made and recommended
improvements are given.
