Le fluide de travail (5, 51, 52, 53) en surpression (P+, P+1, P+2, P+3) et le fluide de travail (6, 61, 62, 63) en dépression (P-, P-1, P-2, P-3) sont appliqués simultanément au sous-réseau (2, 21, 22) entre le premier raccord (3, 31, 32) et le second raccord (4, 41, 42), de telle manière qu'un écoulement (7) du fluide de travail (5, 51, 52, 53) en surpression (P+, P+1, P+2, P+3) vers le fluide de travail (6, 61, 62) en dépression (P-, P-1, P-2, P-3) se produise dans une direction dans le sous-réseau (2, 21, 22), entre le premier raccord (3, 31, 32) et le second raccord (4, 41, 42) du sous-réseau (2, 21, 22). Selon l'invention, dans au moins une étape de traitement la direction de l'écoulement (7) dans le sous-réseau (2, 21, 22) est inversée au moins une fois entre le premier raccord (3, 31, 32) et le second raccord (4, 41, 42). L'invention concerne en outre un sous-distributeur (81) pour la mise en oeuvre du procédé de l'invention, ainsi qu'un dispositif de traitement comprenant un sous-distributeur (81).
