Abstract
Low and medium pressure, high temperature, fluid washers for pressure cleaning surfaces, vessels, piping, tubing, and other structures having a tri-plex pump downstream of a fluid heater in which the high pressure pump employs a barrier seal system with circulating fluid.
Claims24
A method of generating pressurized fluid, comprising:
- pressurizing fluid with a first fluid pump to increase a fluid pressure to a first pressure or a first pressure range;
- coupling a heat exchanger to the first pump capable of increasing a temperature of the fluid pressurized by the first pump to a second temperature or a second temperature range;
- pressurizing fluid from the first pump or from the heat exchanger with a second fluid pump to a second pressure or second pressure range greater than the first pressure or first pressure range;
- circulating fluid from the first pump into at least a portion of the second pump without the second pump pressurizing the circulated fluid;
- and
- generating fluid selected from the group:
- (1) fluid pressurized by the first fluid pump only;
- (ii) fluid pressurized by the first fluid pump and heated by the heat exchanger but not pressurized by the second pump;
- (iii) fluid pressurized by the first and second fluid pumps but not heated by the heat exchanger;
- and (iv) fluid pressurized by the first fluid pump, heated by the heat exchanger, and pressurized by the second pump.

A method of generating pressurized fluid, comprising:
- drawing fluid from a source with a first pump;
- pressurizing the fluid with the first pump to a first pressure or a first pressure range;
- providing a fluid heater capable of increasing a temperature of the fluid pressurized by the first pump to a second temperature or second temperature range;
- pressurizing with a second pump fluid from the first pump or fluid from the fluid heater to a second pressure or second pressure range greater than the first pressure or first pressure range;
- the second pump comprising a pump plunger and a barrier seal forming an annular chamber around a portion of the plunger;
- providing a fluid heater bypass that selectably communicates fluid from the first pump to the second pump bypassing the fluid heater;
- providing a second pump bypass that selectably communicates fluid bypassing the second pump;
- circulating fluid from the first pump into the annular chamber of the barrier seal and back to the fluid source;
- providing a controller operatively coupled to the first pump, the fluid heater, the second pump, the first pump bypass, the second pump bypass, to generate fluid selected from the group:
- (1) fluid pressurized by the first fluid pump only;
- (ii) fluid pressurized by the first fluid pump and heated by the heat exchanger but not pressurized by the second pump;
- (iii) fluid pressurized by the first and second fluid pumps but not heated by the heat exchanger;
- and (iv) fluid pressurized by the first fluid pump, heated by the heat exchanger, and pressurized by the second pump.
