Abstract:
A differential vapor pressure (DYP) cell is disposed in a divided wall column that receives a feed comprising a first, second, and third component. A separation section on the feed side of the divided wall column separates the feed in a vapor comprising the first and second component, and a liquid comprising the second and third component. The DYP cell is disposed in the divided wall column at a level below the point where the feed enters the column, and the DYP cell measures the concentration of the first component.
Abstract:
Described is a method for recording the boiling curve of liquids, in particular petroleum products and/or solvents, in which a sample amount of the liquid to be analyzed is evaporated and subsequently condensed, wherein the vapor temperature and the respectively evaporated amount of liquid are monitored, the sample amount is dosed by a a pump, for example, wherein the pump and the condensate collection chamber are brought to a defined, and preferably identical, temperature level. The condensed volume is determined volumetrically and the distillation residue of the sample amount is determined by weighing.
Abstract:
A control apparatus and control method for controlling the separation in a dividing wall distillation column of at least two feeds into at least three products is disclosed. The apparatus uses a temperature measuring device to measure the temperature of fluid in the column, a controller, and a means for adjusting the temperature of fluid in the column. The temperature measuring device may be on either side of the dividing wall or above or below the dividing wall, and more than one such device may be used. The apparatus and method may be used in the production of alkylaromatic hydrocarbons by alkylating aromatic hydrocarbons with olefinic hydrocarbons.
Abstract:
The invention relates to a sea water desalination installation that employs an evaporation-condensation system which operates continuously at a low temperature and which enables the recovery of energy released. The inventive installation comprises a cylindrical evaporator having a large evaporation surface and a concentric condenser with a large surface area. Sea water is used to cool the condenser and said water is subsequently sent to the evaporator. A static high-pressure ventilator is used to: (i) drive the vapour/air in a closed circuit between the evaporator and the condenser and (ii), using a calibrated nozzle, create a pressure gradient that is equivalent to the pressure of the saturated vapour at working temperature between said two zones. The aforementioned evaporator and condenser are thermally insulated in relation to one another and to the external environment.

Abstract:
A distiller (10) that employs a rotary heat exchanger (32) introduces water to be evaporated into evaporation chambers (56). During most of its operation, it collects the water that has passed through the evaporation chamber (56) without evaporating, and it reintroduces the thus-collected liquid back into the evaporation chamber, where it also adds a minor amount of unrecirculated feed liquid to make up for evaporation and concentrate removal. Simultaneously, a minor amount of feed liquid is fed into one side of a transfer pump (116). During this mode of operation, the impurities concentration in the recirculating liquid tends to increase as a result of the evaporation of pure water vapor. Periodically, the erstwhile recirculating liquid is redirected to the other side of the transfer pump (116), where it causes the feed liquid stored in the transfer pump's first side to be fed without accompanying recirculant liquid into the rotary heat exchanger's evaporation chambers. After a short time, the normal flow is restored, and the liquid from the rotary heat exchanger that had been redirected into the transfer pump's other side is discharged slowly as distiller concentrate. The resultant impurities concentration in the concentrate output can be as much as nearly twice the average impurities concentration experienced by the heat exchanger's evaporation-chamber surfaces.

The manifold is designed to create a suction in the drain line to enhance draining of the boiling tank.
Abstract:
A process and device for purifying organically polluted waste water utilizing a primary system and a closed secondary system. The primary system includes a first heat exchanger, a second heat exchanger and a cyclone located between the two heat exchangers. The first heat exchanger evaporates the waste water into a waste water vapor and a waste water sump solution. The heat for evaporating the waste water in the first heat exchanger is obtained primarily from raw water in the secondary system. A second heat exchanger in the primary system condenses the waste water vapor and in the process causes evaporation of raw water in the secondary system. The level of waste water in the primary system is monitored as is an operational parameter in the secondary system. With the data obtained from this monitoring, the drawing off of the waste water sump solution is controlled.
Abstract:
A water purification device mounted within a housing adapted to be positioned on an existing water cooler/dispenser has a valve control member extending from the base of the housing and is positionable within the water reservoir of the dispenser to control the release of purified water from the device to the reservoir. The device includes a feedwater tank into which supply water is fed and which feeds water to a water level control tank which communicates with the bottom of a boiler which is maintained at the same level as the water in the control tank. The control tank includes a control valve which maintains the water in it to a predetermined level above the level of the heating element in the boiler. The boiler is connected to condenser coils for condensing vaporized water from the boiler to form distilled water which is directed through a carbon filter to a distillate storage tank where the purified water is stored until required by the water cooler/dispenser. Baffles above the boiler heating element preclude heated water from being driven into the condenser.
