Video description

Se va a eliminar el 86.4% del H2S que contiene un agua amarga, utilizando una columna empacada con arreglo en contracorriente, que trabaja a presión y temperatura constante, y esta instalada a nivel del mar. Las condiciones de operación son de 75ºC y Pman=31.3 lb/in2. Para ello, se alimenta por el domo, la fase líquida con 3 667 partes por millón en peso de H2S. Esta corriente se pone en contacto con metano libre de H2S, que a la salida tiene una composición de 1 283 mm Hg. La fase líquida sigue la Ley de Henry y a las condiciones de operación de la columna, la constante tiene un valor de H=1 254 atm/fracción mol fase líquida. La fase gaseosa se puede considerar ideal. Los pesos moleculares son: 34 para el H2S, 16 para el metano y 18 para el agua. La densidad de la fase líquida se puede considerar constante en cualquier punto de la columna, siendo la gravedad específica de 0.98. Calcular: La composición de H2S a la salida de la fase líquida, en porciento peso. El porciento de exceso utilizando de fase gaseosa. El caudal de fase gaseosa alimentada (medido a 1.2 atm y 25ºC), por cada kilogramo de H2S recuperado. Los kmol de fase líquida alimentada por cada kmol de mezcla gaseosa que sale de la columna. La composición máxima a la que puede alimentarse la fase gaseosa, en mm Hg.
