  • Patent number: 8496787
    Abstract: A method and apparatus for eliminating brine effluent from desalination plants by distillation, is disclosed. To eliminate the brine the salt is converted into a solid and all of the water in the brine is converted to distilled water. The key to achieving this is reducing or eliminating the scale formation in the heating chamber. In one embodiment the process can be used to reduce or eliminate scale formation in a vapor compression sea water desalinization system and there-by use this system to produce drinking water. This process requires no chemical additives but relies entirely upon separation of the process of vaporization of the fluid involved, from the process of heating of the fluid. In one embodiment of this apparatus sea water can be desalinated and the resulting products can be dry salt and pure water leaving no brine return to the ocean.

  • Patent number: 8287698
    Abstract: The present invention relates to a process and a system for producing alcohol by distillation with energy optimization using split-feed technology. The process of the present invention comprises the steps of: a) splitting a stream of wine to feed two depuration columns , the depuration column generating a stream of phlegma and the depuration column generating a stream of phlegma and a stream of vinasse; b) feeding the stream of phlegma into at least one rectification column generating a top flow and a stream of hydrated alcohol; c) effecting the heat exchange between the top flow from at least one rectification column and the stream of vinasse from the depuration column in at least one heat exchanger; and d) feeding the stream of phlegma into a rectification column generating a stream of hydrated alcohol. The present invention further relates to hydrated alcohol produced by the process described above and to a process for producing anhydrous alcohol.

  • Patent number: 8273220
    Abstract: A distillation column is disclosed. The column includes a plurality of rectification zones and corresponding stripping zones. Each rectification zone is linked to a heat pump or a stage of a heat pump. Overhead material from the top rectification zone is compressed and used to heat bottoms liquid from the bottom stripping zone. Similarly, overhead material from a lower rectification zone is compressed and used to heat liquid taken from the uppermost or top stripping zone. Optionally, overhead material from a middle rectification zone is compressed and used to heat liquid from a middle stripping zone. A single multiple stage heat pump compressor may be utilized as opposed to a plurality of heat pumps. Because the heat exchanger from each rectification-stripping zone pair has a lower duty, economical stab-in heat exchangers may be utilized.

  • Patent number: 8252148
    Abstract: A mobile waste processing system and method is disclosed for processing materials in a tank, typically an underground storage tank. A mobile fluid processing module is disposed adjacent to or over the tank, and sealingly connected to the tank through a tank riser. Support equipment, which may include an electric power module, a chiller module, a heating module, and a control and monitor module, are disposed a distance from the processing module, and connected thereto. A pump and optionally a dispersal nozzle are deployed from the processing module into the tank, and effluent is extracted for processing. The processing trailer includes effluent processing equipment such as an evaporator and demister, condenser, vacuum pump, and interim storage tank. The effluent is processed, and at least a portion is removed. Some of the processed effluent may be returned to the tank.

  • Patent number: 8246816
    Abstract: One exemplary embodiment can be a separation zone for separating a plurality of naphtha components. The separation zone can include first and second columns. The first column may include a dividing imperforate wall with one surface facing a feed and another surface facing a side stream. Typically, the wall extends a significant portion of the column height to divide the portion into at least two substantially vertical, parallel contacting sections. Also, the second column can communicate with the first column so as to provide a feed to or receive a feed from the first column. Generally, the second column is non-divided. The separation zone may provide at least four product streams.

  • Patent number: 8231765
    Abstract: A method and a plant are disclosed for purifying lactams, particularly lactams obtained by cyclizing hydrolysis of aminonitrile. The purification of ?-caprolactam obtained by cyclizing hydrolysis of aminocapronitrile is described which includes eliminating the ammonia from the reaction medium of the hydrolysis, then recovering the lactam from the medium in purified form. The recovery is carried out by performing at least a distillation of the lactam in the presence of a base producing optionally a fronts fraction having compounds more volatile than the lactam, a fraction having the lactam to be recovered to the degree of desired purity and a distillation tails having the lactam and compounds less volatile than the lactam. The distillation tails are treated by various processes such as evaporation in thin layers to recover the major part of the caprolactam and recycling the latter in the purification process.

  • Patent number: 8192588
    Abstract: Water is removed from oily water produced during operation of a separation column by withdrawing the oily water from the column during separation into an external separator where the oily water is separated into a water phase and an oily phase. The oily phase is then heated to a temperature effective to produce a density differential that drives the oily phase back into the operating column.
