What is the purpose of the pre-hydrogenation unit with a deoxygenation tower process?

Generally, for reformation pre-hydrogenation, the process involves a stripping tower and a fractionation tower; if an oxygen removal tower is added beforehand, how will the oil in the system circulate at the start of operation? Does anyone know?

During oil transportation, it uses a reaction crossover to connect with the two towers following it, passing by the pre-hydrogenation reactor.

Deoxygenation is used to prevent oxygen from reacting with olefins at high temperatures to form polymer deposits in heat exchangers or reactor beds.
