    Summary: Effect of the pulsation plates frequency and solvent ratio on thecolumn extractor efficiency has been examinated.Efficiency of theseparation of phenol from water using butylacetate as a solventhas been investigated in the column extractor with perforatedpulsation plates.From the relations between process parametersconclusions could be drawn about the interaction of the solventratio and frequency of the plates on the NTU,interface and theefficiency of separation.
    Keywords: Pulsation,plate,solvent ratio,efficiency,column extractor.

    Title: THE INFLUENCE OF PLATE GEOMETRY ON THE SEPARATION EFFICIENCY OF THE PULSED COLUMN EXTRACTOR

    Summary: A study of the influence of plate geometry on the separationefficiency of the pulsed column extractor was performed.Fourforms of plates,with different hole diameters and placements wereused so thed free area space varied from 13 % to 35 %.The systemwater-phenol-buthyl acetate was investigated.The obtained resultspoint to the conclusion that process parameters are highlydependent on the hole diameters and their placement on the platesof extraction column.Increased values of the solvent ratio causean increase of NTU.Efficiency of the separation process using "A"type plates led to the expected saturation.Plates with 22 % offree area space (type"C") gave the best results and could belinearly regresed.Variations on the curves representing changesof effciency for plates of "A" and "D" types will be the subjectof furher investigations.Process parameters are highly dependenton the hole diameters and their placement on the plates ofextraction column.The best results were reached with perforated"C" type plates.
    Keywords: Pulsed column extractor,efficiency,separation,plate geometry.

    Title: THE INFLUENNCE OF PLATE GEOMETRY ON THE SEPARATION PROCESS USING PULSED COLUMN EXTRACTOR

    Proceedings title: PROCEEDINGS
    Language: engleski
    Place: BARCELONA, Španjolska
    Year: 1993
    ISBN/ISSN: D.L.:B-32.328
    Pages: from 151 to 152

    Held: from 10/18/93 to 10/20/93
    Summary: A study of the influence of plate geometry on the separationefficiency of pulsation column extractor was performed.Thelaboratory deisgned apparatus with dimensions: diameter 0.05m,hight 0.80 m and 16 perforated plates was used.Four shapes ofplates,with different hole diameters and placement were used,andfractional free area of plates was changed from values 13 % to 35%.The capacity rate and mass transfer coefficient for systemwater-phenol-buthylacetate was investigated.Concentration ofphenol in feed was approximately up to the 0,001 kg/kg.Fromobtained results one could concluded that changing of values ofthe solvent ratio and plate geometry are mean parameters for thedescription of the investigated separation process.The bestresults in this research work were obtained with the perforatedplates whose fractional free area was 22 % for choosen solventratios and plate frequency.
    Keywords: exstraction,plate geometry,mean diameter,capacity coefficient,mass transfer coefficient,efficiency.
