A seawater distillation system for distilling seawater and brine and removing salt. The seawater distillation system includes an apparatus having at least a vessel, a separation assembly, and at least one mist eliminator. The vessel may be adapted to hold a volume of seawater comprising a volume of salt, wherein vessel is one of externally heated and internally heated to evaporate the volume of seawater to a volume of steam and to precipitate the volume of salt. The separation assembly may be operably engaged with the vessel, wherein the separation assembly is configured to separate the volume of salt from the volume of seawater inside of the vessel. The at least one mist eliminator may be operably engaged with the vessel and positioned vertically above the separation assembly, wherein the at least one mist eliminator is configured to eliminate water droplets and salt from the volume of steam.

A heat transfer process focused for heat transfer with a potentially scaling, fouling, solids laden or otherwise aggressive fluid employing direct thermal contact between said fluid and an immiscible, phase shifting working media wherein said phase shifting proffers the employ of the latent heat of vaporization for protraction of the heat transfer process. Wherein further said phase shifts modify the working media density therein motivating the immiscible, direct contact fluid dynamics.

The present disclosure is a method of removing contaminants from a feed stream comprising said contaminants and process liquid by bringing the feed stream into contact with a heated heating fluid in or in proximity to a separation vessel thereby causing process liquid to vaporise and flow out of the separation vessel as vapour, after which it can be recovered. Embodiments of the method may include using a heavy heating fluid whose density is higher than that of the feed stream and/or vigorously agitating the pool of heating fluid in the separation vessel.

Disclosed are a process for operating a flashline heater and a flashline separation system. In the process and system, heat is supplied to the flashline heater by a first steam stage followed by a second steam stage. The steam pressure is controlled by a steam control system such that the pressure in the first steam stage is not equal to the pressure in the second steam stage. Also disclosed is a process for retrofitting a steam control system in a flashline separation system of an olefin polymerization system at least by changing the number of steam stages in the flashline separation system to include a first steam stage followed by a second steam stage, and changing the stream pressure control scheme such that the pressure in the first steam stage is independently controlled to be not equal to the pressure in the second steam stage.

Provided herein are compositions and processes concerning efficient downstream processing of products derived from organic acids pretreatment of plant materials.

A process of producing potable water, by combining a hydrocarbon containing fossil fuel with oxygen, in a combustion device, such as a home heating or utility unit to produce a flue gas of water vapor and carbon dioxide, and condensing the water vapor in the flue gas to yield potable water. The combustion device can produce heat or electricity. The water vapor can be condensed with one or more heat exchange devices. The source of oxygen can be air, pure oxygen, or nitrogen reduced air. The source of oxygen can be humidified, such as with a non-potable water source or non-potable water can be added to the flue gas. The carbon dioxide and/or nitrogen in the flue gas can be reduced or removed before the condensation step(s). The pressure of the flue gas can be increased prior to condensation of the water vapor. Natural gas is a preferred fuel.

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.

The disclosure pertains to a urea production process using a first and a downstream second evaporator in an evaporation section, a finishing section and a scrubber for treating off-gas of the finishing section. Condensate from the condenser of the second evaporator is supplied to the scrubber.
