Our Bisulfite Production Systems come fully assembled and skid-mounted, complete with controls, piping, and valves. These systems are automated for safe, accurate production, and can be maintained by a single operator. Flow rates can be varied as required.
We offer the following systems. Other systems may be available dependent on the customer’s needs and feasibility of the project.
Ammonium Bisulfite ((NH4)HSO3) Production Systems can produce various weights of ammonium bisulfite using aqueous ammonia and dry sulfur dioxide (SO2).
Potassium Bisulfite (KHSO3) Production Systems can produce various weights of potassium bisulfite using 32% to 45% potassium hydroxide (KOH) solution and dry sulfur dioxide (SO2).
Sodium Bisulfite (NaHSO3) Production Systems can produce 40% by weight sodium bisulfite using 32% or 50% sodium hydroxide (NaOH) solution and dry sulfur dioxide (SO2).
Cooling towers, cooling water pumps, and raw material pumps are available for these systems, upon request.
The Bisulfite Production Systems provide an accurate and repeatable final product allowing for precise product specifications and reduced raw material losses. These systems are 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 system shuts 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.
