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.
Claims15
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 extending into said tank and leading from said tank a pump effective to pump water through said recirculation loop;
- dispensing means from said recirculating water loop.
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, dispensing said recirculating water into said process stream.
