Ammonia removal from delimiting effluent by stripping-reabsorption / Dennis J. O'brien in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXI (Année 1986)
[article]
Titre : Ammonia removal from delimiting effluent by stripping-reabsorption Type de document : texte imprimé Auteurs : Dennis J. O'brien, Auteur ; Gerard E. Senske, Auteur ; Michael Komanowsky, Auteur Année de publication : 1986 Article en page(s) : p. 125-136 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The removal of ammonia nitrogen from tannery deliming effluent was studied in a pilot scale stripping and reabsorption operations were carried out in columns packed with one-inch Tellerettes. Ammonia removal efficiency in the stripping column was a strong function of the liquid/gas flow rate ratio. At air loading rates of 630-830 cfm/ft² column cross-sectional area, high ammonia removal efficiencies (>95%) could only be achieved at liquid loading rates of 1.5 gpm/ft² column cross-sectional area or less. The effects of process variables are discussed and design data are presented.

Titre : An acoustic emission study of staking and fatliquor Type de document : texte imprimé Auteurs : Paul L. Kronick, Auteur ; Angela R. Page, Auteur ; Michael Komanowsky, Auteur Année de publication : 1993 Article en page(s) : p. 178-186 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The chemical treatment leather with fatliquor and physical treatment of staking produce similar esthetic results. The effects of two such different treatments on the structure of the leather, however, and perhaps various other responses to deformation, are expected to be different. The equivalence of fatliquoring and staking were investigated by comparing the effects of the treatments on the stress-strain curves and the acoustic emission observed during tensile testing. It was found that staking affects only the first 25% of the elongation at break, lowering the initial modulus, while fatliquors affect the whole stress-strain curve. The initial part becomes concave upward instead of downward, and the elongation and stress at failure are greater. Acoustic emission from leather that was merely staked was suppressed only at small elongations, while it was smaller at all elongations from leather that had fatliquor. The results are shown to be consistent with a domain model of deformation. A nondestructive determination of the elongation of leather at tensile failure, based on acoustic emission, is derived from the observations.

PerméabilitéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : We have constructed a model of air permeability taking into account appropriate parameters. Two of the parameters which represent the capillary radius and the amount of capillaries in a definite area of leather, respectively r and n have been deduced.
Researches on the locational differences in air permeability based on the model, show that different locations of leather have different values for r and n. The capillary radius of samples near the head location ranges from 452.9nm to 479.1nm, while the quantity of capillaries in the same sample is the greatest, from 7.948 x 1011/m2 to 8.617 x 1011/m2. The capillary radius (r) of a sample from a near centre location is the largest at 581.0nm and the capillary amount (n) is the lowest at only 5.262 x 1011/m2. The capillary radii of samples near the tail and centre of the leather are about 530nm.
Neither the thickness nor aperture ratio can successfully represent the air permeability of leathers. The air permeability process is rather complex. Using only the capillary radius (r) or the quantity of capillaries in a definite area (n) does not allow us to express the air permeability adequately.Note de contenu : - Foundation of the air permeability model and the deduction of parameters

Cuirs et peaux -- SéchageIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : This paper considers the physics and chemical engin-eering aspects of the drying process and how the drying characteristics of leather may be analysed.
To understand the drying process it is particularly valuable to look at the rate at which materials dry at various stages of the process. Drying rates give useful dues to the mechanism by which moisture moues and hence to the factors which will affect the quality characteristics of the product. A knowledge of the mechanisms of moisture transport also helps to establish the significance of the process variables, such as drying medium temperature and product thickness.Note de contenu : - Fig. 1 : Drying rate curves for non-porous hygroscopic, porous non-hygroscopic and porous hygroscopic materials (from Keey)
