Claims
- 1. An apparatus useful for providing a chemical composition useful to treat a piece of equipment comprising:
- a reservoir for containing a concentrated form of said chemical composition, said reservoir having an outlet through which said concentrated form of said chemical composition exits said reservoir;
- a concentrate pump adapted to pump, at a time rate and at a controlled time, the concentrated form of said chemical composition from said reservoir;
- a flow assembly coupled to said concentrate pump and a source of diluent and being adapted (1) for providing, at a time rate and at a controlled time, diluent from said source of diluent directly to a piece of equipment to be treated, and (2) for providing, at a time rate and at a controlled time, a chemical composition comprising diluent directly from said source of diluent and said concentrated form of said chemical composition directly from said reservoir directly to the piece of equipment to be treated; and
- a control assembly associated with said concentrate pump and said flow assembly and structured to be preset to, automatically and independently of the diluent flow, control the time during which said concentrated form of said chemical composition exits said reservoir and to automatically and independently control the time during which said diluent flows in said flow assembly.
- 2. The apparatus of claim 1 which further comprises a nozzle coupled to said flow assembly to facilitate contacting said diluent and said chemical composition with the piece of equipment to be treated.
- 3. The apparatus of claim 2 wherein said control assembly automatically controls the movement of said nozzle.
- 4. The apparatus of claim 1 wherein said control assembly comprises an electronic controller including a keyboard and a display module, said electronic controller being structured to be preset by control information imputed through said keyboard, and said display module being adapted to provide a visual display of said control information imputed through said keyboard.
- 5. The apparatus of claim 4 which further includes an alarm assembly associated with said control assembly and being adapted to be preset by alarm information imputed to said control assembly to provide a signal warning of an abnormal condition in one or more components of said apparatus.
- 6. The apparatus of claim 4 wherein said electronic controller includes a computer.
- 7. The apparatus of claim 1 wherein said flow assembly is adapted to provide said diluent and said chemical composition on a once-through basis.
- 8. An apparatus useful for providing a plurality of different chemical compositions useful to treat a piece of equipment comprising:
- a plurality of reservoirs each of which is for containing a concentrated form of a different one of said chemical compositions, each of said reservoirs having an outlet acting to provide an exit from the associated reservoir for the concentrated form of the chemical composition contained in said associated reservoir;
- a plurality of concentrate pumps each of which is operatively coupled to a different one of said plurality of said reservoirs and is adapted to pump, at a time rate and at a controlled time, the concentrated form of the chemical composition contained in the operatively coupled reservoir;
- a flow assembly coupled to said concentrate pumps and a source of diluent and being adapted (1) for providing, at a time rate and at a controlled time, diluent directly from said source of diluent to a piece of equipment to be treated, and (2) for providing, at a time rate and at a controlled time, each of a plurality of chemical compositions, each of which comprises diluent directly from said source of diluent and a concentrated form of said chemical composition directly from said reservoir containing said concentrated form of said chemical composition, directly to the piece of equipment to be treated; and
- a control assembly associated with said reservoirs and said flow assembly and structured to the preset to, automatically and independently of the diluent flow, control the time during which said concentrated form of chemical composition exits from each of said reservoirs and to automatically and independently control the time during which said diluent flows in said flow assembly.
- 9. The apparatus of claim 8 wherein said control assembly is adapted to control the time during which said concentrated form of chemical composition exits each of said reservoirs so that a controlled sequence of individual chemical compositions is provided to the piece of equipment to be treated.
- 10. The apparatus of claim 8 which further comprises a nozzle coupled to said flow assembly to facilitate contacting said diluent and said chemical compositions with the piece of equipment to be treated.
- 11. The apparatus of claim 10 wherein said control assembly automatically controls the movement of said nozzle assembly.
- 12. The apparatus of claim 8 wherein said control assembly comprises an electronic controller including a keyboard and a display module, said electronic controller being structured to be preset by control information imputed through said keyboard, and said display module being adapted to provide a visual display of said control information imputed through said keyboard.
- 13. The apparatus of claim 12 which further comprises an alarm assembly associated with said control assembly and being adapted to be preset by alarm information imputed to said control assembly to provide a warning signal of an abnormal condition in one or more components of said apparatus.
- 14. The apparatus of claim 12 wherein said electronic controller includes a computer.
- 15. The method of claim 8 which includes three of said concentrate pumps.
- 16. The apparatus of claim 8 wherein said flow assembly is adapted to provide diluent and said chemical compositions on a once-through basis.
