摘要

The invention relates to a process (10) for producing propylene, comprising: carrying out a method (1) for propane dehydrogenation in order to obtain a first component mixture (A); carrying out another propylene production method (2) in order to obtain a second component mixture (B); and forming a separation product (P2) predominantly containing propane, by means of at least one propane separation step (S1), at least part of the first component mixture (A) being supplied to the at least one propane separation step (S1). According to the invention, the separation product (P2) predominantly containing propane is to be at least partially recirculated into the other propylene production method (2). The invention further relates to a corresponding facility and to a method for retrofitting a steam cracking facility (30).
