Abstract
QUE COMPRENDE: a)PROPORCIONAR UNA FUENTE DE ABSORBENTE GRASO (FA) DE TEMPERATURA ENTRE 60 Y 150°C A UN ELIMINADOR DE OXIDO DE ETILENO (EO), QUE EN CONTACTO A TEMPERATURAS ELEVADAS CON UNA FUENTE DE GAS DE ELIMINACION SE OBTIENE UN ABSORBENTE MAGRO ELIMINADO (LA) Y UN GAS CON EO; b)PROPORCIONAR UNA O MAS FUENTES DE CORRIENTE DE PROCESO EXTERNO AL ELIMINADOR DE EO, EN UN LUGAR ENCIMA DE LA FUENTE DE FA A UNA TEMPERATURA ENTRE 10 Y 80°C, PARA CONCENTRAR EO EN EL GAS CON EO; Y, c)REMOVER LAS IMPUREZAS, TALES COMO HIDROCARBUROS CLORINADOS, POR UNA O MAS SALIDAS LATERALES DEL ELIMINADOR DE EO. LA CORRIENTE DE PROCESO EXTERNA SE SELECCIONA DE CORRIENTE DE FA, CORRIENTE DE AGUA O CORRIENTE DE EO, Y SUS FUENTES INCLUYEN FA DE UN ABSORBENTE DE EO PARA FORMAR (A) POR CONTACTO DE GAS CON EO Y VAPORES CON (LA) DE FASE ACUOSA, O INCLUYE FA DE ABSORBENTES DE GAS RESIDUAL (RA) PARA FORMAR FA POR CONTACTO DE EXTREMOS LIVIANOS CON (EO) RESIDUAL CON (LA). EL DISPOSITIVO INCLUYE: UN ELIMINADOR DE EO CON UNA ENTRADA DE FA, UNA ENTRADA PARA GAS DE ELIMINACION, SALIDAS PARA ABSORBENTE MAGRO ELIMINADO Y PARA EO, Y UNO O MAS ENTRADAS UBICADAS POR ENCIMA DE LA ENTRADA DE FA PARA UNA O MAS CORRIENTES DE PROCESO EXTERNA. UN CONDENSADOR INTERNO DE AGUA FRIA, SE SUMINISTRA EN LA PARTE SUPERIOR DEL CONCENTRADOR DE ELIMINACION DE EO QUE GENERA UN REFLUJO Y QUE CONCENTRA LA SOBRECABECERA. EL PROCESO ES PARTE DE UNO PARA CONVERTIR (E) EN EO, CON FORMACION DE H2O Y CO2, Y LUEGO EN ETILENGLICOL, O PURIFICAR EO
