Abstract

"This thesis deals with the desing and construction of reactor-litle mil for the haired-leather tanning at EL ALCE tanning factory in the Guano canton which will serve for the product diversification. Though the experimental metod a pilot equipment was constructed; tests were carried out to demostrate the process effectiveness. The following materials were used: a recycled PVC tank, a stainless steel base, piping and a pump. On the basis of preliminary tests this Batch type reactor was constructed with 0.222 m3 capacity,0.87 m high,0.57 m diameter and 1 Hp power pump.The lab tests show values higher than 2.5 % chromium oxide absorption in the leater tanned in all the stops; due to the fact that in the country a Leather Norm of this type has not been elaborate the Emvironmental Reference System (SIRAC) used in the tanning sector of Colombia in which: 2.5% minimum for and efficient tanning is established, as a Norm has been adopted. The skins tanned in this reactor meet the above norm thus demonstrating its effectiveness. The country tanning industries are recommended to incorporate this reactor to their industry and artisan plants for product diversification and economy."
