Abstract
Patente de Invenção: <B>"RECUPERAçãO DO áLCOOL DE ALQUILA INFERIOR A PARTIR DE UMA MISTURA DE EXTRAçãO"<D>. Métodos para a remoção de um álcool de alquila inferior a partir de uma mistura de poliéster de poliol de ácido graxo e de álcool de alquila inferior compreendem: a) pór em contato a mistura de poliéster com uma mistura de extração compreendendo um gás inerte de extração, até cerca de 10.000 ppm de álcool de alquila inferior e até cerca de 2.000 ppm de oxigênio, em que, pelo menos uma parte do álcool de alquila inferior é transferida a partir da mistura de poliéster para a mistura de extração, aumentando por essa razão a concentração do álcool de alquila inferior na mistura de extração, b) separar a mistura de extração da mistura de poliéster. Os métodos compreendem ainda c) comprimir a mistura de extração para aumentar a pressão da mesma; d) resfriar a mistura de extração para reduzir a sua temperatura, condensando por esse motivo, pelo menos uma primeira parte do álcool de alquila inferior para o estado líquido, e) separar o álcool de alquila inferior condensado a partir da mistura de extração para reduzir a quantidade de álcool de alquila inferior na mistura de extração para uma faixa a partir de cerca de 1 ppm até cerca de 10.000 ppm, e f) direcionar a mistura de extração resultante para uma turbina de expansão na qual a temperatura e a pressão da mistura de extração são reduzidas. A energia que resulta a partir da redução na temperatura e na pressão da mistura de extração na turbina de expansão é usada para comprimir a mistura de extração separada da mistura de poliéster.
