Title: Distillation device
Inventor: UEDA SADAJI
IPC: B01D61/10
Filed: 1980-12-01
Abstract: PURPOSE: To make components which are more volatile than water to be sepa- rable from the bottom liquid of a distillation device by incorporating a reverse osmotic membrane type separator into an ordinary distillation device.  
     CONSTITUTION: The distillation bottom liquid is pressurized by a pump 11 and fed to the reverse osmotic membrane type separator 9 through heat exchangers 12, 13. In the separator 9, the bottom liquid is separated into a concentrated liquid in which the components more volatile than water are concentrated, and a permeated liquid in which the components are diluted. Then, the permeated liquid is discharged via a discharge pipe 15, while the concentrated liquid is fed back to a heating drum 2 after its pressure is lowered to a predetermined pressure. Accordingly, by only supplying energy enough for pressurizing the distillation bottoms, the separating effect is enhanced remarkably and problems of an azeotropic composition in carrying out the separation can be overcome. This device is extensively used for the distillation of a solution in which water is a higher-boiling component, for example, an aq. alcoholic solution.

Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To enable alloying at high speed by specifying a dew point at reducing atmosphere from a specific temp. at the time of recrystallize-annealing to a specific temp. in a cooling stage after reaching the max. temp. and a dew point just before dipping into a galvanizing bath, and executing galvanizing and alloying. SOLUTION: The dew point from 600 deg.C at the time of recrystallize-annealing to 700 deg.C in the cooling stage after reaching the max. temp., is regulated to 0 deg.C-20 deg.C, and the dew point just before dipping into the galvanizing bath is regulated to <=-20 deg.C. It is desirable to use a steel containing >=0.01 wt.% P. The suitable atmosphere at the time of executing anneal-reduction, is an N2 atmosphere containing <=2% H2 , and the dew point of <=700 deg.C at the temp. of anneal-heating is ordinally the one between the dew point at 700 deg.C and the dew point just before galvanizing, because the dew point just before galvanizing is regulated to <-20 deg.C. However, any dew point is not surely regulated. The productivity can be improved by quickening a line speed and the deterioration of the galvanized quality can be prevented.
