Подскажите, пожалуйста, как можно перевести термин swing reactor в контексте установки каталитического риформинга с периодической регенерацией катализатора.

Контекст:
Catalytic reforming processes are commonly classifi ed according to the frequency
and mode of catalyst regeneration, into (1) semiregenerative, (2) cyclic
regeneration, and (3) continuous regeneration. The main difference among the
three types of processes is the need of unit shutdown for catalyst regeneration
in the case of a semiregenerative process, the use of an additional SWING or
spare reactor for catalyst regeneration for the cyclic process, and catalyst
replacement during normal operation for the continuous regeneration type.

Заранее спасибо!

хотя "сменно-циклическая установка" звучит гораздо, согласен)))
