Abstract
METODO PARA OBTENER HIDROCARBUROS DE C2 A PARTIR DE LOS VAPORES DE CABEZA DE UNA COLOMNA DESMETANIZADORA, CARGADA CON UNA COMPOSICION QUE CONTIENE HIDROCARBUROS DE C2 EN MEZCLA DE HIDROGENO, METANO E HIDROCARBUROS DE C3+. COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, CONDENSAR UNA PORCION DE LOS VAPORES DE CABEZA, PROCEDENTES DE LA COLUMNA DESMATANIZADORA (11), EN EL CONDENSADOR DE REFLUJO PRINCIPAL (15); SEGUNDA, EL LIQUIDO CNDENSADO, DESPUES DE SER SEPARADO DE LOS VAPORES, EN EL SEPARADOR DE FASES (16), ES DEVUELTO A LA COLUMNA DESMETANIZADORA; TERCERA, LOS VAPORES NO CONDENSADOS, SEPARADOS EN EL SEPARADOR DE FASES (16), QUE CONTIENEN HIDROCARBUROS RESIDUALES C2 SE INTRUDUCEN EN UN DELFLEGMADOR (21), DONDE SE ESTABLECE UN INTERCAMBIO DE CALOR INDIRECTO CON UN FLUIDO REFIGERANTE, EFECTUANDOSE UNA CONDENSACION DE PARTE DE LOS COMPONENETES DE LA CORRIENTE DE VAPOR, LO QUE DA LUGAR A LA FORMACION DE LA CORRIENTE DE LIQUIDO DE REFLUJO QUE FLUYE HACIA ABAJO.
