Potassium Hydroxide Dilution System

Our Potassium Hydroxide (KOH) Dilution System is designed for the accurate dilution and high-volume transfer of concentrated potassium hydroxide solution into railcars, tank trucks, and storage tanks. As an alternative to diluting with water, a stronger solution can be blended with a weaker solution to produce an intermediate concentration. Systems can be used for bulk loading of specific batch quantities or set up to operate continuously based on demand, such as automatically maintaining scrubber tower systems.

For applications where the heat of dilution must be controlled, a plate heat exchanger can be integrated into the design. A Powell supplied heat exchanger will yield a dilute product temperature that is 5°F (-15°C) greater than the supplied cooling water temperature. Cooling towers, cooling water pumps, and raw material pumps are available upon request. We can also provide a static mixer, to be installed downstream of the system, in order to ensure proper mixing of raw materials when plate heat exchangers are not necessary.

This system comes fully assembled and skid-mounted, complete with controls, piping, valves, and instrumentation. It is engineered for a project specific flow rate, concentration ranges and accommodates blending of multiple raw material streams and any required additives. A properly sized system can reduce the number of necessary storage tanks at a given facility since only concentrated feedstock and water would need to be stored.

The system provides an accurate and repeatable final product allowing for precise product specifications and reduced raw material losses. It is programmed to instantly auto-adjust stream flow rates in the event of a process upset. If the process upset cannot be corrected automatically, the system will stop, protecting pumps and ensuring consistent product quality. The systems shut down upon high or low tank level.

Our systems are supported by our experienced technicians who can provide startup, operator training, or perform scheduled preventive maintenance and calibration. Additional charges may apply for these services.
