Techniques are described herein for using a high-pressure reactor to separate clean water from dirty water without filtration and to extract and concentrate contaminants from dirty water for use as a fuel. In particular, techniques and systems are described for separating water from hydrocarbon contaminates, other BTU-laden compounds, and dissolved minerals, while also boiling water and condensing the resulting steam into distilled water. In addition, system in which the described techniques are performed can be used as a high-pressure pump for moving the separated hydrocarbon contaminates forward into other processes, such as a high-pressure reactor or incinerator.

The present invention relates to a system and method using a reservoir specially designed for desalinating sea water. The invention makes it possible to evaporate the sea water and condense the resulting vapor at low pressure. Discharges into the sea resulting from said desalination operations have a low salt concentration. The present system and method can be used to recycle energy, even energy which is difficult to recycle, for desalinating sea water, or can be combined with other desalination techniques, for example such as MSF evaporation or MED distillation.

A system and method for the pyrolysis of a pyrolysis feedstock utilizes a pyrolysis reactor having a pyrolysis conduit and a solids return conduit segment. Each segment is configured with an outlet and an inlet to receive and discharge solid materials that are circulated through the reactor through the different segments. A solids conveyor is disposed within the pyrolysis conduit segment to facilitate conveying solid materials from the solids inlet upward through the pyrolysis conduit segment toward the solids discharge outlet. A pyrolysis feedstock is introduced into the pyrolysis reactor and at least a portion of the feedstock is converted to pyrolysis gases within the pyrolysis conduit segment, which are discharged through a gas outlet. An eductor condenser unit with an eductor assembly having a venturi-restricted flow path for receives a pressurized coolant fluid. A second flow path for receiving the discharged pyrolysis gases intersects the venturi-restricted flow path so that the received pyrolysis gases are combined with the coolant fluid and are discharged together to a mixing chamber that is used to condense pyrolysis gases.
