A plant for dealcoholising alcoholic beverages includes a rectification column having at least one inlet for the alcoholic beverage, a sump and a top. The rectification column is operable such that dealcoholised beverage can be removed from the sump and exhaust vapour can be removed from the top. At least one evaporator is configured to supply the rectification column with vapour. A condenser arrangement condenses the exhaust vapour removed from the top of the rectification column, at least in part. The plant further includes a heat pump which can operate the evaporator as well as the condenser arrangement. A method for dealcoholising alcoholic beverages in a rectification column is also disclosed.

The system for drying lignite according to the present disclosure includes a mill configured to crush the lignite; a dryer configured to receive crushed lignite from the mill, to dry the lignite by heat-exchange with steam and to discharge dried lignite; a condensing-precipitating evaporator in fluid communication with the dryer so as to receive vapor which is evaporated when the lignite is dried, and which is discharged from the dryer. The evaporator is configured to condense the vapor discharged from the dryer by heat-exchange with water. The coal dust contained in the vapor is precipitated into a condensed aqueous solution when the vapor is being condensed, and the condensed aqueous solution is discharged. The system includes a Mechanical Vapor Re-Compression (MVR) configured to receive steam generated from the condensing-precipitating evaporator, to compress the steam into superheated steam, and to supply the compressed superheated steam to the dryer.

An apparatus and system for producing fresh water from moisture-laden air. The apparatus has a frame supporting a plurality of condensation panels that each have a panel body defining a pair of condensation surfaces that will contact the moisture-laden air. A panel support mechanism supports each of the condensation panels in spaced apart relation to each other so each condensation surface contacts moisture-laden air. A flow channel inside the panel body defines a flow path for a cooling fluid that cools the condensation surfaces so the moisture-laden air will produce condensate thereon that collects as fresh water. The system includes a plurality of apparatuses, a chilling mechanism to cool the cooled fluid, inlet and discharge lines connecting the chilling mechanism and apparatuses, pumps to pressurize the cooled fluid, fans to move the moisture-laden air and water collecting surfaces to collect the fresh water.

Described are a high pressure carbamate condenser, urea plant, and urea production process. The high pressure carbamate condenser as described is of the shell-and-tube heat exchanger type with a tube bundle and has a redistribution chamber connected to tubes of the tube bundle and to a duct. The duct extends between the redistribution chamber and the shell.

The invention relates to an arrangement for a latent-heat exchanger chamber, usable in distillation devices, which comprises an evaporator in a capillary evaporation regime on the inner face thereof and a condenser in a capillary condensation regime on the outer face thereof, with a system for the dosed supply of liquid into microgrooves or micro undulations of the inner evaporator face, preventing the formation of thin films of water on the evaporator face, the arrangement achieving high latent-heat transfer coefficients.

The present invention consists of a method for producing heat transfer between two or more media and a device or system for carry out said method, usable for air conditioning a space, or any use that requires heat transfer between two or more media, and may be liable to be used for domestic, commercial or industrial use.

Apparatus for producing liquid water from the condensation of atmospheric water vapor includes a transportable housing defining a first air inlet, a second air inlet, and an air outlet; first and second doors operable selectively to open and close the first and second air inlets, respectively; and at least one water condensation unit located in the housing between the first air inlet and the air outlet, and between the second air inlet and the air outlet. The housing is configured so that, when at least one of the first and second air inlets is open, at least a portion of an air flow into the at least one open air inlet is passed through the at least one condensation unit and out the air outlet.

A mobile vacuum distillation unit for extracting, condensing, and collecting volatile organic compound vapor emissions from one or more polymer-containing articles includes a shell that defines an enclosed interior space and is mounted to a transportable support platform, a vacuum distillation vessel, a condenser, a condensate storage tank, and a vacuum pump system in fluid communication with a vacuum distillation chamber of the vacuum distillation vessel. The vacuum distillation chamber that includes the one or more polymer-containing articles from which the VOC vapor emissions are extracted may be heated by an exhaust gas heat exchanger if the transportable support platform is connected to and hauled by a tractor unit powered by a diesel engine. A method of using the mobile vacuum distillation unit to extract VOC vapor emissions from one or more polymer-containing article during transportation of the one or more polymer-containing articles between geographically separate destinations is also disclosed.

The invention provides several innovations relative to MVC thermal distillation methods and facilities in order to decrease their specific electricity consumption to values of only 2 to 4 kWh/m3 of distillate produced, as well as their manufacturing costs. The vapour transport system is reduced to its simplest expression and has a practically null total dynamic pressure loss. The compression system including the compressor motor) is completely integrated into the evaporator-condenser, installed in the inlet of the condensation zones, preferably provided with a system preventing overheating of the vapour, and driven at a high speed of rotation. Preferably, the auxiliary equipment is installed in the enclosure in a partial vacuum (hermetic chamber). According to one particular embodiment, the condensation zones have a section that decreases with the path of the vapour. The exchangers on the incoming and outgoing flows are supplied with continuously balanced heat loads. Heat losses are offset by auxiliary heating. Preferably, the facility can be made using a modular concept.
