Abstract: The system and method for steam production for oil production. The method includes generating steam from an indirect heat exchange system, mixing the steam with water containing solids and organics, separating solids, and injecting the steam through an injection well or using it above ground for oil recovery, such as for generating hot process water. The system includes a steam drive direct contact steam generator. The water feed can be hot produced water separated from a produced oil emulsion and/or low quality water salvaged from industrial plants, such as refineries and tailings from an oilsands mine.

Abstract: The present invention is a system and method for generating a mixture of steam and combustion gas in a direct contact rotating steam generator, using high solids content water, and without waste liquid discharge. The invention includes removing the solids with controllable water content in a stackable form. The system includes a longitudinally rotatable and controlled pressure enclosure being mounted at a slope and having a steam producing section, a water injection section and a discharge section. The enclosure can include a mixing and mobilizing rotating element to enhance the mixture and the heat transfer. The system can have an additional wet section to scrub contaminates and produce saturated steam. The system can be integrated with an enhanced oil recovery facility or with an open mine oil facility that generates non-segregate tailings to consume their discharge liquid waste and generate steam, heat and a stable solids waste.

Abstract: The present invention is a method and system for vertically producing a steam and combustion gas mixture, typically used in enhanced oil recovery processes. The system is a fluid bed up-flow combustor system, including a vertical vessel with fours sections. In a first section, fuel, oxidizer, and possibly water are supplied to the high pressure combustor at a combustion section of a vertical vessel. The combustion gas from the first section flows to a second section for steam generation, where low quality water is injected and turned into steam. Next, the third section is a homogenizer vessel, where any remaining water drops are converted to steam and solid particles and discharged from the vessel. The fourth section located at the bottom of the vessel is a fluid bed, receiving and processing the falling solids from the combustion and the steam generation sections.
