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.

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.

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.
