Description: Plan 02 is a dead‐ended seal chamber with no
recirculation of flush fluid.
Objective: Often used with a jacketed seal chamber to control
temperature in high temperature processes. Use only when
adequate vapor margin is present in the seal chamber.
Advantages: Little to no maintenance. Process solids are not
continuously introduced into seal chamber. Plan 62 with steam
can provide additional heating or cooling and minimize coking
on hot processes.
