Typical Potassium Bisulfite Skid

Potassium (PSO3) Bisulfite Production Systems from Powell are available to produce various weights of potassium bisulfite using 32% to 45% potassium hydroxide and dry sulfur dioxide (SO2) gas, wet sulfur dioxide gas, or liquid sulfur dioxide out of railcars, iso containers, or tank trucks.

The systems are automatic and include pumps and heat exchangers for the safe, accurate production of potassium bisulfite. The system can be started by an operator and flow rates can be varied as required. Remote mounted pumps for potassium hydroxide supply and water for dilution of 32 or 45% potassium hydroxide are typical options. A cooling tower with pump is a typical option used for cooling the process.

Many options exist for the equipment such as:

  • 316 SS pipe and fittings for dilution systems of sodium hydroxide
  • PTFE lined pipe and fittings
  • Teflon lined steel ball and plug valves
  • Dual laminate tank
  • Tefzel lined magnetic drive pumps
  • Rosemount, Yokogawa and Endress Hauser instrumentation typical
  • Masoneilan control valves
  • Allen Bradley PLC systems

This skid can be configured for multiple bisulfites such as sodium, potassium, magnesium, and ammonium.
