Abstract: The present disclosure relates to an integrated treatment method of two-stage submerged combustion evaporation for organic waste liquid, the organic waste liquid to be disposed flowing into two evaporation chambers in succession for two-stage submerged combustion evaporation. The two evaporation chambers are provided in one evaporation tank and communicate with each other at the bottom of the evaporation tank, the organic waste liquid enters a first evaporation chamber from a raw liquid inlet pipe, and the organic waste liquid flows from the first evaporation chamber to a second evaporation chamber during submerged combustion evaporation. The method has advantages of improving the evaporation concentration efficiency, reducing the numbers of evaporators and transport pipes of all sorts of gases and liquids and saving energy, saving the area occupied and the cost, while simplifying treatment process and facilitating operation management.

Abstract: The methods improve the separation of hydrocarbon containing fluids. More particularly, the disclosure is relevant to separating fluids having a gas phase and a hydrocarbon liquid phase using indirect heating. In general, the methods use a first gas separation step followed by indirect heating and then a second gas separation step. Pressure reduction of the hydrocarbon containing fluid occurs either before or after the indirect heating.

The system may provide hydrogen at variable pressures (including relatively higher pressures) that match changing operating pressures of the reactor supports systems as the reactor cycles through startup and shutdown modes.

Abstract: An apparatus for receiving and processing organic waste by anaerobic bioconversion comprising a closed tank which is the bioconversion site, provided in the top portion thereof with a gasometric bell for storing and pressurizing the biogas produced, around which the external members of the apparatus are distributed on a pod which also forms the support for a body of the digester. The tank, in a preferred embodiment, comprises a main enclosure which is the bioconversion site, and a secondary central enclosure called the crop, intended to receive and store the organic waste to be processed before the dosing of same into the main enclosure to complete the bioconversion. The crop forms a removable subassembly that can be configured in different ways, with a circulation and distribution block on which it is secured and with a liquid-solid phase separator which is mounted over same.

Abstract: The methods improve the separation of hydrocarbon containing fluids. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the methods use a first three-phase gas separation stop followed by indirect heating and then a second three-phase gas separation step. Pressure reduction of the hydrocarbon containing fluid occurs either before or after the indirect heating.

Abstract: A radial flow hydrothermal reactor for a sludge thermal hydrolysis treatment is provided. An outer and an inner cylinder are successively sleeved in a cylindrical body of the reactor. A guiding cylinder is arranged between the outer and the inner cylinder. Guiding pipes are provided on the guiding cylinder. An agitator is arranged in the inner cylinder, so that sludge has low viscosity and good fluidity after reaching reaction parameters. Because an inlet pipe is arranged below the inner cylinder, the sludge enters the inner cylinder from bottom and flows out from top, and the inner cylinder has a diameter not large, which guarantees heating time. Because of a small height-to-diameter ratio of the reactor, the sludge after heating has the good fluidity, and flows outward radially in the outer cylinder. With an increased flowing radius, a flowing velocity decreases, and a hydrothermal reaction proceeds continuously, which guarantees reaction time.

Abstract: The hydrogen-powered desalination plant is a multi-stage flash desalination system using hydrogen fuel to power the top brine heater of the plant. The hydrogen-powered desalination plant includes a plurality of flash distillation stages, which each include a flash chamber and a condenser. The top brine heater in the hydrogen-powered desalination plant is powered by the carbon-free combustion of hydrogen gas with oxygen gas. The combustion of the hydrogen gas with the oxygen gas creates a flame, which is used directly to generate steam from atomized seawater, any seawater not converted to steam being collected as preheated brine and passed to the multi-stage flash desalination system for successive stages of flash distillation. Preferably, the flame is generated as a vortex.

Abstract: The general concept of this invention is to utilize the high efficiency of heat transfer that is obtained by allowing the exhausting gas from the burner to come into intimate contact with the liquid to be heated. A housing adapted for partial immersion in the liquid of the tank and has an internal liquid heating chamber and defines inlet and outlet openings. A burner tube is supported within the housing and extends into the liquid and provides a combustion gas discharge opening. A burner assembly having a supply of combustible gas and air is in communication with the burner tube and has a burner nozzle being positioned to direct a flame into the burner tube. The burner tube has sufficient length for substantially complete combustion of a gas/air mixture within said burner tube and to discharge hot combustion gas into the liquid within said internal liquid heating chamber. The flame and hot combustion gas efficiently heat the liquid circulating through the chamber via the inlet and outlet openings.

Abstract: A high-efficiency hydronic heating system will make use of a direct-fired steam generator to directly heat the water in the hydronic heating system. The products of combustion, present with the steam due to the steam generator being direct-fired, are also introduced into the hydronic heating system water. Before venting the products of combustion from the packed column, heat from these products of combustion is extracted in a secondary heat exchanger to preheat the combustion air before it is used in the direct-fired steam generator. Water is a product of combustion. Over time, this excess water will overfill the hydronic heating system if it is not removed. A water dump system is used for the removal of the excess water. By measuring the water removed and the fuel used in the direct-fired steam generator, an efficiency can be calculated for visual feedback. The products of combustion will also tend to cause the water in the hydronic heating system to become acidic.
