摘要： The invention relates to a system and device for desalination by liquid water jet compression, which is a phase-change desalination with a high-efficiency latent heat exchanger in which the pressure of the primary saturated vapor is increased until obtaining the secondary saturated vapor by injecting translational and rotational kinetic energy via pressurized water jets, so as to leave an unobstructed path through which the vapor flows at high speed in order to achieve a high flow rate and high efficiency.

摘要： A saline feed stream flows into a liquid-liquid extraction system; and a volatile organic solvent flows through a main compressor. The compressed volatile organic solvent then flows through a solvent regenerator, which can be a heat exchanger or a combination of a vaporization device and a condenser, to cool the volatile organic solvent. The cooled volatile organic solvent in liquid phase then flows into the liquid-liquid extraction system, where the saline feed stream contacts the volatile organic solvent to selectively extract water from the saline feed stream into the volatile organic solvent, producing a concentrated brine and an organic-rich mixture of water and the volatile organic solvent. The organic-rich mixture flows from the liquid-liquid extraction system into the solvent regenerator, where the organic-rich mixture is heated to produce an organic-rich vapor and desalinated water; and the organic-rich vapor is recycled as volatile organic solvent back into the liquid-liquid extraction system.

摘要： The present invention utilizes mechanical vapor compression and/or thermal vapor compression integrating compression loops across multiple process stages. A sequential network of compressors is utilized to increase the pressure and condensing temperature of the vapors within each process stage, as intra-vapor flow, and branching between process stages, as inter-vapor flow. Because the vapors available are shared among and between compressor stages, the number of compressors can be reduced, improving economics. Balancing vapor mass flow through incremental compressor stages which traverse multiple process stages by splitting vapors between compressor stages enables the overall vapor-compression system to be tailored to individual process energy requirements and to accommodate dynamic fluctuations in process conditions.

摘要： The present invention relates to an improved method for removing contaminants from a gaseous stream substantially comprising carbon dioxide. More specifically, the method comprises the step of subjecting the gaseous stream to an absorption step in which the absorbent is liquid carbon dioxide wherein the waste of carbon dioxide is minimized by utilizing a compressing means for generating a pressure difference between two streams in a reboiler.

摘要： A distillation apparatus includes an evaporator-condenser heat exchanger in combination with a compressor. The heat exchanger is mounted to float in an at least partially immersed position in a sump of liquid. The liquid may be a sap, or may be soiled water, and may have suspended solid. Heating of the liquid yield steam, the steam is compressed, and the heated, compressed steam is fed back into the heat exchanger to provide further heat to the liquid. The process yields a concentrated in the liquid bath and distilled water, each of which may be a desired product. The system may include a pre-heater that exchanges residual heat from the hot distillate with the cooler input liquid. The apparatus and process may have multiple stages.
