Plan 62 (Quench Line)

Outboard
Plan 62 is a common plan to improve the environment on the atmospheric side of single seals by quenching with steam, nitrogen or water.
Plan 62

Why do we use it?

  • When the outboard leakage of a seal is an oil which may coke or degrade in contact with atmosphere (steam or N2)
  • When the outboard leakage of a seal may crystalise, or polymerise (water)
  • When the outboard leakage of a seal may solidify (water or steam)
  • When the outboard region is prone to icing

Advantages:

Plan 62 is a low cost alternative to tandem seals. The quench prevents or retards product crystallization or coking. Quenches can also provide some cooling.

General:

Typical applications; steam quench on hot services to retard coking, nitrogen quench on cold or cryogenic service to prevent icing, or water quench to prevent crystallization or accumulation of product on the atmosphere side of the seal. May be used with or without a steam deflector. For steam quenches a steam trap is recommended. A pressure indicator is optional.
