Abstract
Disclosed herein are systems and processes which prevent fouling of a reactor inlet of an oligomerization reactor. The systems and processes involve placement of an inlet sleeve around at least a portion of a reactor inlet such that a curtain of inert material flows through an annular space coaxially with respect to an outer surface of the end of the reactor inlet and into the reactor.
Claims20
A process to prevent fouling at a reactor inlet, the process comprising:
- flowing a reactant into a reactor via the reactor inlet such that the reactant is introduced to an interior of the reactor via an end of the reactor inlet;
- and
- flowing an inert material into the reactor coaxially with respect to an outer surface of the end of the reactor inlet;
- wherein the inert material flows coaxially with respect to the outer surface of the end of the reactor inlet via an annular space formed between an inner surface of an inlet sleeve and the outer surface of the reactor inlet;
- and
- wherein an exit plane of the end of the reactor inlet is spaced apart from an exit plane of an end of the inlet sleeve.

A system to prevent fouling of a reactor inlet, the system comprising:
- a reactor;
- a reactor inlet coupled with the reactor such that an end of the reactor inlet extends into an interior of the reactor;
- and an inlet sleeve coupled with the reactor such that an end of the inlet sleeve extends into the interior of the reactor,
- wherein the inlet sleeve is placed coaxially around at least a portion of the reactor inlet such that an annular space is formed between an outer surface of the reactor inlet and an inner surface of the inlet sleeve;
- and
- wherein an exit plane of the end of the reactor inlet is spaced apart from an exit plane of the end of the inlet sleeve.
