Abstract

SE PRESENTA UN SISTEMA DE PROCESAMIENTO DE UN EFLUENTE QUE CONTIENE NITROGENO, A PARTIR DE UN PROCEDIMIENTO INDUSTRIAL EN EL QUE EL EFLUENTE ES ENFRIADO Y EL NITROGENO LIQUIDO SE AÑADE DIRECTAMENTE AL EFLUENTE ENFRIADO. EL CONTACTO DIRECTO Y EL INTERCAMBIO DE CALOR PRODUCE NITROGENO GASEOSO Y PRODUCTOS ORGANICOS LIQUIDOS, QUE SE UTILIZAN AMBOS PARA ENFRIAR EL EFLUENTE Y SON, POSTERIORMENTE, RECUPERADOS.
