V. Alessi et al., CAPROLACTAM PRODUCTION - A COMPARISON OF DIFFERENT LAYOUTS OF THE LIQUID-LIQUID-EXTRACTION SECTION, Chemical engineering & technology, 20(7), 1997, pp. 445-454
Two different layouts for the liquid-liquid ex:traction section of an
industrial caprolactam process are evaluated. Laboratory mass transfer
measurements on streams obtained from an industrial and a demonstrati
on plant with different extraction sections are interpreted by a model
describing the effect of surface contaminants on mass transfer coeffi
cients. Indications of the impact of these layouts on the complexity o
f the extraction section, quality of products and efficiency of the ex
traction processes are given.
