The following thesis work aims to analyze the main steps in the development of a working prototype useful for the recovery of R134a from the mixture coming from RPCs. They are preceded by some phases of testing and experimentation on a first prototype which allowed to identify and correct some useful parameters during the design phase of the new prototype. Afterwards, the construction phase was analyzed in detail, with special attention to the criticalities that arose during this phase, which were corrected and verified once the prototype was completed. In addition, the electronics and software programming part was also taken care of, with a specific focus on functional analysis and the PLC used to manage the prototype.
