Description: Plan 03 is a dead‐ended seal chamber with an
open throat, tapered seal chamber and flow modifiers to
generate product circulation.
Objective: Dissipate seal generated heat, vent and drain the
seal chamber, and aid in the removal of solids.
Advantages: Little to no maintenance. Process solids will not
collect as they do in a traditional seal chamber. Use only when
adequate vapor margin is present in the seal chamber. Plan 62
with steam can provide additional heating or cooling and
minimize coking on hot processes.
