摘要： A desalinization process and apparatus utilizing a humidity chamber having a saltwater structure; a cooling water structure and a salt-free water collection structure. Saltwater having a first temperature and cooling water having a second temperature are introduced into the humidity chamber. The temperature difference between the saltwater and the water running through the water coil create a temperature gradient causing salt-free water to distill from the saltwater. The salt-free water is then collected.

摘要： A method for removing a contaminant from a fluid feed stream containing the contaminant. The method includes the steps of providing a feed stream and heating it in a first step to at least partially remove some of the contaminants and recover energy from a concentrate and distillate generated. Further heating the feed stream in a second heating step in a heated separator generates a saturated vapor fraction and a concentrated liquid contaminant fraction. The vapor fraction may be compressed to generate a temperature differential in the reboiler exchanger with the vapor fraction being passed into contact with a reboiler exchanger to provide a stream of condensed vapor from the reboiler. The stream may be circulated through the reboiler exchanger and the heated separator to maintain from about 1% to about 50% by mass vapor in the stream. The apparatus includes a unique configuration of a vapor compressor, heated separator in combination with a forced circulation circuit to generate the decontamination result.

摘要： A device allows for continuous regulation of the composition of a fluid mixture that includes at least two components of different polarities. The device is designed, for example, to be inserted in a separation system that the device supplies with a carrier fluid of stabilized composition. The device includes a storage tank (3) receiving a mixture coming from the separation system and at least one auxiliary vessel (6) containing one of the components of the mixture. To control the transfer of this component from auxiliary vessel (6) to storage tank (3), the device further includes at least one tubular capacitive sonde (CS) totally immersed in the fluid mixture, a sonde (TS) for measuring the temperature of the mixture, and a sonde (LS) for measuring the mixture level in storage tank (3). A regulating unit (10) is connected to the various sondes to determine the volume of the component to be transferred to storage tank (3) from the at least one auxiliary vessel in order to restore a set composition for the mixture. The device can be used, for example, for the control of simulated moving beds, of distillation columns, etc.

摘要： An improved design of a vapor compression distiller which makes use of a rapid, highly turbulent flow through the heat-of-evaporation recovery, or primary, heat exchanger. The distiller may also include the use of turbulators to increase turbulence and mixing within the primary heat exchanger. The increased level of turbulence and mixing dramatically reduces fouling inside the primary heat exchanger and increases the heat transfer efficiency. The improvements in the distiller are maximized by recirculating the liquid to be evaporated at a high multiple of the flow rate of the liquid feed to the distiller. The distiller may also include a feed circulation loop with a secondary heat exchanger to increase the efficiency of heat-of-evaporation recovery in the evaporation/condensation cycle. Applications of the vapor compression distiller include purification of waste liquids, concentration of dilute liquid mixtures, and separation of liquid/liquid, liquid/gas, and liquid/solid mixtures.

摘要： A system and method for purifying liquefied corrosive gases of metallic impurities is described. The principle for this purification method relies on vapor-phase transfilling the vapor phase from a source container into a receiving container. This method has been observed to decrease metal concentrations by a factor of at least 1000 and, decreases the metallic impurity levels in the resulting condensate. The vapor transfer is accomplished by controlled differential pressure rather than mechanical pumping, thereby generating no particle or metal impurities.
