Title
(ES) PROCEDIMIENTO PARA LA PREPARACION DE ALQUIL ETERES Y MEZCLAS DE LOS MISMOS.
Abstract
(ES)
LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE PREPARACION DE ALQUIL ETERES TERCIARIOS, EN PARTICULAR MTBE, ETBE O MEZCLAS DE DICHOS ETERES CON ETERES MAS PESADOS. SEGUN DICHO PROCEDIMIENTO, LA CORRIENTE DE ALIMENTACION QUE CONTIENE HIDROCARBUROS SE ALIMENTA A UN SISTEMA REACTOR DE DESTILACION CATALITICA, EN EL CUAL LAS ISOOLEFINAS, ESPECIALMENTE LAS ISOOLEFINAS C 4 A C 7 DE LA CORRIENTE, SE HACEN REACCIONAR CON UN ALCANOL, EN PRESENCIA DE UNA RESINA DE INTERCAMBIO CATIONICO, A FIN DE PRODUCIR PRODUCTOS DE ALQUIL ETER TERCIARIOS. EL PRODUCTO DE REACCION QUE CONTIENE DICHOS ETERES SE ELIMINA DEL SISTEMA DE DESTILACION COMO PRODUCTO DE FONDO Y, SI ES NECESARIO, SE SOMETE A UN TRATAMIENTO ADICIONAL PARA PRODUCIR UN COMPONENTE DE GASOLINA. EL ALCANOL QUE NO HA REACCIONADO SE ELIMINA COMO PRODUCTO DE LA PARTE SUPERIOR DE LA COLUMNA DE DESTILACION. SEGUN LA INVENCION, EL DESTILADO RETIRADO CONTIENE PRINCIPALMENTE UN AZEOTROPO DE HIDROCARBUROS C 3 Y ALCANOL, CUYA CANTIDAD DE C 3 CORRESPONDE AL MENOS APROXIMADAMENTE A LA CONCENTRACION DE HIDROCARBUROS C 3 DE LA CORRIENTE DE ALIMENTACION HIDROCARBONADA. UNA CANTIDAD CONSIDERABLE DEL ALCANOL QUE NO HA REACCIONADO SE ELIMINA EN FORMA DE AZEOTROPO. POR MEDIO DE ESTA INVENCION SE ELIMINA LA NECESIDAD DE UNA UNIDAD DE LAVADO DE ALCANOL SEPARADA EN EL APARATO, LO CUAL REDUCE CONSIDERABLEMENTE LOS COSTES DE INVERSION DEL SISTEMA.
