Abstract
LA INVENCION SE REFIERE A UN PROCESO PARA LA SEPARACION DE ACIDO (MET)ACRILICO A PARTIR DE LA MEZCLA DE REACCION DE LA OXIDACION DE FASES GASEOSAS CATALITICAS MEDIANTE ABSORCION EN CONTRA CORRIENTE CON UN LIQUIDO ORGANICO HIDROFOBO INERTE DE EBULLICION ALTA, EN DONDE LA MEZCLA DE REACCION SE GUIA A UNA COLUMNA DE ABSORCION EN CONTRACORRIENTE CON EL LIQUIDO ORGANICO HIDROFOBO INERTE DE ALTA EBULLICION QUE SUBE Y A CONTINUACION SE SEPARA DE MANERA RECTIFICATIVA EL ACIDO (MET)ACRILICO A PARTIR DEL CIRCUITO DE DESARROLLO DE LIQUIDO DE LA COLUMNA DE ABSORCION QUE CONTIENE EL ACIDO (MET)ACRILICO. EL PROCESO DE ABSORCION QUE SIGUE DE MANERA NATURAL A LA COLUMNA DE ABSORCION SE SOBRECARGA CON UN PROCESO DE RECTIFICACION DE TAL MODO QUE TIENE LUGAR, EN LA COLUMNA DE ABSORCION MEDIANTE CONTACTO CON LA ATMOSFERA DEL AMBIENTE, LA EXTRACCION DE LA CANTIDAD DE ENERGIA EN DISPOSICION DE CESION ENERGETICA NATURAL.
