Systems and methods for improved mixing

Abstract

Systems and methods for improved mixing, including baffle systems, reactor systems, and methods of using the same are provided herein. These baffle systems include a ring having an exterior surface defining an outer diameter and an outer circumference, an interior surface defining an inner diameter and an inner circumference, a top surface, a bottom surface, and an axis; and one or more substantially vertical baffles extending from the interior surface of the ring toward the axis.

Description

[0001] Cross References to Related Applications [0002] none. technical field [0003] The present application relates to systems and methods for improving mixing, and more particularly to baffle systems and reactor systems and methods of use thereof. Background technique [0004] Many chemical reactors require agitation and mixing to ensure uniform distribution of their contents. To improve mixing in chemical reactors, internal baffles can be added. However, these internal baffles are not suitable for use in high pressure processes such as low density polyethylene (LDPE) processes because the attachment means used to attach the baffles to the reactor impairs the ability of the reactor to withstand these high pressure conditions. In particular, ports or bolt holes created to attach internal baffles often become initiation points for cracks, which can lead to stress rises and ultimately failure of components or the entire reactor. Similarly, welding baffles to the reacto...

However, these internal baffles are not suitable for use in high pressure processes such as low density polyethylene (LDPE) processes because the attachment means used to attach the baffles to the reactor impairs the ability of the reactor to withstand these high pressure conditions

Specifically, the ports or bolt holes created for the attachment of internal baffles often become the initiation points for cracks, which lead to stress rises and eventual failure of components or the entire reactor

Similarly, welding baffles to the reactor reduces the integrity of the reactor metal, making it more susceptible to crack initiation and propagation
