ABSTRACT:
A system and a method of its use for the accelerated cooldown of at least one reactor by injecting liquid carbon dioxide via a sparger into a pipeline connected to the reactor via a access valve upstream of the reactor. By providing an evenly distributed flow into the system gas prior to entry into the reactor, the system and its method of use efficiently and uniformly cooldown the reactor. In a preferred embodiment, multiple spargers using this technique can cooldown multiple reactors in series.
