Abstract

Procedimiento para la extracción de lanolina de la lana y planta para la realización de dicho procedimiento. Comprende las fases de: paso de una mezcla extractora formada CO{sub,2} o un hidrocarburo de cadena corta a alta presión y entre el 5 y el 40% en peso de un cosolvente polar, preferiblemente acetona o etanol, a través de lana comprimida a una densidad aparente comprendida entre 106 y 460 kg/m{sup,3}, dentro de una cámara extractora (1, 2), formando una disolución de lanolina extraída en la mezcla extractora; separación, en un primer separador (3), de la lanolina de la mezcla extractora; recirculación del gas y del cosolvente a la cámara extractora; evaporación de la mezcla extractora, en un evaporador (4); expansión y condensación del gas separado y de la mezcla extractora, en un expansor- condensador (5); recirculación del cosolvente o de la mezcla extractora; y compresión de la mezcla extractora. La extracción se realiza a una presión comprendida entre 70 y 500 bar y a una temperatura comprendida entre 30 y 80º C.Procedure for the extraction of lanolin from the wool and plant for performing said procedure. It comprises the phases of: passing an extractive mixture formed CO {sub, 2} or a short chain hydrocarbon at high pressure and between 5 and 40% by weight of a polar cosolvent, preferably acetone or ethanol, through wool compressed at an apparent density comprised between 106 and 460 kg / m {sup, 3}, within an extractor chamber (1, 2), forming a lanolin solution extracted in the extractor mixture; separation, in a first separator (3), of the lanolin from the extractor mixture; gas and cosolvent recirculation to the extractor chamber; evaporation of the extractor mixture, in an evaporator (4); expansion and condensation of the separated gas and the extractor mixture, in an expander-condenser (5); recirculation of the cosolvent or extractor mixture; and compression of the extractor mixture. The extraction is carried out at a pressure between 70 and 500 bar and at a temperature between 30 and 80º C.
