Methods and systems for heating and manipulating fluids

A fluid rehabilitation system, comprising:

• a holding tank configured to retain a first fluid and comprising a first fluid circulation loop configured to circulate the first fluid within the holding tank;
• an oxidizer supply component configured to supply a pre-determined amount of oxidizer to the first fluid in the holding tank to generate an oxidized first fluid;
• a separation subsystem configured to receive oxidized first fluid and to separate from the oxidized first fluid particulate contaminates to generate filtered oxidized fluid;
• a closed-loop heating subsystem comprising a fluid circulation pump and a first path through a fluid-to-fluid heat exchanger, all configured to circulate there through a second fluid at a temperature less than an atmospheric boiling point of the second fluid;
• a fluid concentrating subsystem comprising:
• a second path through the fluid-to-fluid heat exchanger;
• a pump for moving at least a portion of the filtered oxidized fluid through the second path in the fluid-to-fluid heat exchanger to transfer heat from the second fluid to the filtered oxidized fluid in the fluid-to-fluid heat exchanger;
• a flash tank having an orifice through which the heated filtered oxidized fluid is flashed into its liquid and vapor phases to separate at least a portion of water from the filtered oxidized fluid;
• a condensing heat exchanger configured to condense vapor withdrawn from the flash tank to liquid by transferring heat from the vapor;
• and
• an extraction system configured to remove a portion of the liquid phase filtered oxidized fluid from the flash tank as concentrated fluid when a pre-determined property of the liquid phase filtered oxidized fluid is reached.
