Abstract: A portable resonance induction cleaning system for cleaning a process tubular or heat exchanger can include a portable high pressure plunger pump, which can provide a liquid to the portable resonance induction cleaning apparatus. The portable resonance induction cleaning apparatus can regulate flow of the liquid to provide pressurized pulses of the liquid with a resonance for removing fouling. A hose assembly or ram connecting mechanism can provide the pressurized pulses of the liquid to the process tubular or heat exchanger. Air can be used to control flow of the pressurized pulses of the liquid. A hydraulic intensifier can be in fluid communication with the portable resonance induction cleaning apparatus for receiving the air, and a hydraulic control valve can be bi-directionally engaged with the hydraulic intensifier and the hydraulic ram. The hydraulic ram can seal with the heat exchanger to provide the pressurized pulses of the liquid thereto.

Abstract: A portable resonance induction cleaning method for cleaning a process tubular, heat exchanger, or both can include providing a liquid and air to a portable resonance induction cleaning apparatus, and regulating flow of the liquid therein using the air; thereby providing pressurized pulses of the liquid having a resonance. The method can include engaging a hose assembly or hydraulic ram with the portable resonance induction cleaning apparatus, and engaging the hose assembly with the process tubular or sealing the hydraulic ram to the heat exchanger. The method can include continually expelling the pressurized pulses of the liquid into the process tubular or heat exchanger until a standing column of the liquid is formed. The standing column of the liquid can receive the resonance and transmit the resonance through the process tubular or heat exchanger for removing fouling.

Abstract: A method for cleaning tubes and heat exchangers provides an oscillating pump/valve mechanism to provide a periodic waveform of shocks to fouled tubes. Preferably, a pair of pneumatic control valves operates an actuator to oscillate a valve within a valve block, and isolation of a fluid within a manifold in the block creates a pumping action from the valve, to create an intense fluid shock wave to clean interior surfaces tubes.

Abstract: A method for cleaning tubes and heat exchangers provides a cavitation enhancement unit between a source of pressurized fluid an a lance. The pressurized fluid flows through jets, which impart a high speed rotation to a set of propellers, preferably square in profile canted at a 15° angle. Generation of cavitation develops a cleaning vibration in the fluid discharged from the lance.
