Abstract
An apparatus to dispense water soluble compositions into a process stream involves recirculating water through the water soluble chemical held in a tank. The recirculating water is heated to establish a defined temperature and repeatedly recirculated through the bed of chemical to achieve relative saturation concentration of the recirculating water. The water is dispensed from the recirculating unit thereby achieving a consistent concentration of chemical in the dispensed water.
Claims12
An apparatus for adding a water soluble chemical to a process stream comprising:
- a first holding tank adapted to hold said chemical;
- a recirculating water loop comprising:
- a) a water inlet into a bottom portion of said tank;
- b) an outlet from an upper portion of said tank leading to said process stream;
- c) a pump effective to pump water from said outlet into said inlet;
- and a makeup water inlet line to direct fresh water into said tank.
A method of dispensing water soluble chemicals in a process stream comprising holding said chemical in a holding tank, recirculating water through said chemical in said tank, establishing a defined temperature for said water recirculating through said tank, introducing said recirculating water into said process stream.
