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.

A vapor source system based on vapor-liquid ejector supercharging combined with flash vaporization technology belongs to the technical fields of waste heat utilization and steam generation. The system comprises a vapor-liquid ejector, a flash vaporization tank and a intermediate heat exchanger, wherein the vapor-liquid ejector uses high-pressure steam to raise temperature and pressure of low-pressure water absorbed from the flash vaporization tank; the pressure-increased water is flashed into low-pressure saturated steam after entering the flash vaporization tank; the saturated water which is not flashed is collected at the bottom of the flash vaporization tank. The system generates multiple low-pressure flash vaporization saturated steam with a small portion of high-pressure steam, and realizes the recovery and utilization of waste heat such as flue gas of boiler, improves the economy of thermal process, and provides a flexible and adjustable vapor source for heavy oil thermal recovery, seawater desalination or sewage treatment equipment.

The method of generating immediate and thereafter continuous steam is used in a steam generating system comprising a steam accumulator, a steam outlet connected to the steam accumulator, an outlet valve at the steam outlet, and a quick response steam generator unit connected to the steam accumulator. The method comprises the steps of providing latent steam in the steam accumulator, opening the outlet valve to allow latent steam in the steam accumulator to exit through the steam outlet, feeding water to the steam generator unit, heating the water fed to the steam generator unit while the latent steam exits through the steam outlet and, before the latent steam has entirely exited the steam accumulator, generating steam with the steam generator unit to feed the steam accumulator and controlling the steam flow rate through the steam outlet to maintain it at a value which is essentially not greater than the steam flow rate from the steam generator unit to the steam accumulator. The steam generating system is capable of generating immediate and thereafter continuous steam from an initial steam generator unit cold condition due to the steam accumulator providing steam at the steam outlet while the steam generator unit heats the water fed therein.
