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.Type: GrantFiled: February 7, 2007Date of Patent: October 16, 2012Assignees: Siemens Ltda., Dedini S/A Industrias de BaseInventors: Flávio Martins De Queiroz Guimarães, Carlos Eduardo Fontes Da Costa E Silva, Adler Gomes Moura

Patent number: 8273220Abstract: 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.Type: GrantFiled: July 14, 2011Date of Patent: September 25, 2012Assignee: UOP LLCInventor: Paul A.

Patent number: 8252148Abstract: 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.Type: GrantFiled: June 15, 2011Date of Patent: August 28, 2012Assignee: Columbia Energy & Environmental Services, Inc.Inventors: Stephen Wolfe, Brian Brendel

Patent number: 8246793Abstract: Processes for the continuous fractional distillation of a mixture comprising morpholine (MO), monoaminodiglycol (ADG), ammonia and water from a reaction of diethylene glycol (DEG) with ammonia, the process comprising: (i) separating off ammonia from the mixture at a top of a first distillation column K10; (ii) feeding a bottom fraction from the first distillation column to a second distillation column K20, wherein water and an organic product are separated off at a top of the second distillation column at a top temperature of 45 to 198° C. and a pressure in the range from 0.1 to 15 bar; (iii) feeding a bottom fraction from the second distillation column to a third distillation column K30, wherein morpholine and an organic product having a boiling point of <140° C. (1.013 bar) are separated off at a point selected from a top and a side offtake of the third distillation column, and monoaminodiglycol and an organic product having a boiling point of >190° C.

Patent number: 8246816Abstract: 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.Type: GrantFiled: March 4, 2009Date of Patent: August 21, 2012Assignee: UOP LLCInventors: Michael A. Schultz, Xin X. Zhu
