Abstract

Un método y un aparato para determinar la cantidad de diversos materiales en una muestra líquida. Como el aparato es particularmente elástico, se lo puede utilizar de manera repetida con muestras líquidas muy agresivas tales como aguas de bota [boot water] de una refinería de petróleo. El aparato utiliza por lo menos un método óptico de análisis independiente del volumen y/o la concentración para determinar por lo menos uno de: el pH, cantidad de cloruro, y/o cantidad de hierro en la muestra. La propiedad óptica puede ser colorimétrica, de fluorescencia o ambas y puede ser el resultado del agregado de tinturas, agentes complejantes, compuestos inductores de turbidez, y otros reactivos que afectan ópticamente a la muestra. Como las mediciones son independientes de la concentración y el volumen se puede realizar de manera continua, rápidamente, y se evita el inconveniente de los procedimientos de arranque y parada de los regímenes de medición del arte anterior. El método además incluye el uso de una celda BDD para oxidar materiales (tales como los compuestos sulfoxi) que otra manera podrían interferir con el análisis óptico y/o el burbujeo de la muestra con gas.
