Sodium Hydroxide
(Caustic) Dilution System
PowPowell Caustic Dilution Systems are designed for diluting 50% caustic solution
to reduced strengths such as 30%, 25% or 10%. The system is constructed with threaded
carbon steel piping or butt-welded stainless steel piping. Standard flow measurement
is volume based using magnetic flow meters.
Enhanced flow measurement based on the mass & density measurements of the concentrated
caustic is achieved using a Hastelloy C Coriolis meter. This allows the dilution
system to automatically compensate for any variations in the concentrated feedstock.

For applications where the heat of dilution must be controlled, a stainless steel
plate heat exchanger can be integrated into the design of the dilution system. A
Powell supplied heat exchanger will yield a dilute caustic temperature that is 5°F
greater than the cooling water supply temperature.
Powell caustic dilution systems can be used to increase the accuracy of
batch bleach systems, automatically maintaining scrubber tower systems,
bulk loading, and other project specific process requirements.
The Powell Sodium Hydroxide Dilution System is custom designed and engineered for
your projects required flow rate and range of dilute caustic strength. If
required, process water and 50% caustic and cooling water pumps are available from
Powell upon request.
