An apparatus for use in water purification including a cylindrical vessel comprising, within the cylindrical vessel, a first set of hydrocyclones, at least one intermediate set of hydrocyclones, and a final set of hydrocyclones, the sets of hydrocyclones arranged in series. In one embodiment, the hydrocyclones within each set of hydrocyclones are arranged in a parallel configuration, wherein each set of hydrocyclones is defined by a divider which causes the hydrocyclones in each set to operate in parallel. In one embodiment each hydrocyclone has a tangential inlet disposed within an inlet chamber of the cylindrical vessel and in fluid communication with an inlet connected to the inlet chamber, an overflow disposed within an overflow chamber of the cylindrical vessel, and an underflow disposed within an underflow chamber of the cylindrical vessel. In one embodiment, the cylindrical vessel comprises a first set of hydrocyclones and a second, final set of hydrocyclones.

A method for water purification utilizing a cylindrical vessel containing a hydrocyclone nest. The heated contaminated water is fed into the nest, which includes a first set of hydrocyclones, at least one intermediate set of hydrocyclones, and a final set of hydrocyclones, the hydrocyclones in each set arranged in parallel, and each set arranged in series. The heated contaminated water is pumped into the cylindrical vessel such that the heated contaminated water enters a tangential inlet of each of the hydrocyclones, the hydrocyclones separate the heated contaminated water into steam and solids/concentrate, the steam exits through an overflow of the hydrocyclones and a first outlet of the cylindrical vessel, the solids/concentrate exit through an underflow of the hydrocyclones and into the subsequent ser of hydrocyclones until the final set of hydrocyclones, and then out through a second outlet of the cylindrical vessel. The steam is condensed into purified water.

A system and method to reboil a process or feed water stream in a distillation system does so in a liquid pool zone of a vessel as the stream is removed from a distillation column and comes into contact with a heating medium that is immiscible with and less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is partially vaporized, any solids present in the process stream together with the unvaporized process or feed water stream move into the heating medium. These solids and unvaporized liquids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized stream is returned to the distillation column.

A levulinic acid composition A having: a. at least 95 wt. % of levulinic acid; b. between 5 wppm and 5000 wppm of formic acid; and c. less than 1000 wppm of angelica lactone, based on the total weight of the composition. A process for the isolation of a levulinic acid composition, having the following steps: a. performing acid catalyzed hydrolysis of a C6 carbohydrate-containing feedstock to obtain reaction product X, b. subjecting of reaction product X to solid-liquid separation to provide a composition 1, c. feeding composition 1 to at least two purification steps to treat composition 1 to obtain a levulinic acid composition, wherein a second or a further purification step is a melt crystallization step.

The present invention relates to a distributor device (10000) for the even distribution of a fluid (10) into 2 or more fluid streams each containing gas (11) and liquid (12), with a falling film evaporator (100000), in which the distributor device according to the invention serves to distribute the 2 or more fluid streams onto the heating pipes of the evaporator, and to the use of the distributor device (10000) according to the invention and in particular the falling film evaporator (100000) according to the invention in the production and/or preparation of chemical products. The distributor device according to the invention is characterized, in particular, by a swirl breaker (600) for the gas phase (11) which arises from separating the fluid (10) into a gas phase (11) and a liquid phase (12) within the distributor device.

A distillation system used for a distillation process including a distillation chamber having a curved and contoured body, a tube for continuous filling of a liquid solution to be distilled, and a drain hole in a bottom of the body configured for removal of concentrated semi-solid contaminants, and multiple layers of sheets of a flexible material. As designed the curved and contoured body shape of the distillation chamber coupled to the cooled surface (near a point of vapors condensation) creates negative pressure that drives the distillation process and the negative pressure built into the distillation system facilitates and increases distillation and evaporation rates.

A water purification system includes a high temperature water tank, a flameless heat source, a cylindrical vessel (hydrocyclone nest), a first pump, a steam production meter, and a steam condenser and heat exchanger. The contaminated water is heated within the high temperature water tank using the flameless heat source. The heated contaminated water heats the cylindrical vessel and one or more sets of hydrocyclones. The heated contaminated water is pumped into the cylindrical vessel such that the heated contaminated water enters a tangential inlet of the hydrocyclones, the hydrocyclones separate the heated contaminated water into steam and solids/concentrate, the steam exits through an overflow of the hydrocyclones and a first outlet of the cylindrical vessel, the solids/concentrate exit through an underflow of the hydrocyclones and a second outlet of the cylindrical vessel. The steam is condensed into purified water using the steam condenser and heat exchanger.

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 system and method to vaporize a process or feed water stream does so in a liquid pool zone of a vessel as the stream comes into contact with a heating medium that is less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is vaporized, any solids present in the process stream come out of the process stream and move into the heating medium. These solids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized process stream can be further condensed. Any heat recovered can be used to pre-heat the process stream or used in the pump around loop's heater in case of mechanical vapor recovery.
