Help Me.... SRK for Method BP

Help Me.... SRK for Method BP

Help Me.... SRK for Method BP

(OP)
Serve the present one to salute to him, and encarecidamente to ask for to you all the possible aid that it can offer me concerning the method of determination of the bubble point. Which it is put in practices in a modest program designed by my person, which is very simple, but its result vary in a considerable percentage when I compare it with the Flash on the verge of bubble of Pro-II, the deviation this in a compared rank 3 to 5% with the dice in Pro-II, in the Resolution I apply the equation of state of Soave-Redlich-Kwong, which allows to also determine his me enthalpy, but that almost turns aside with mimo error margin, this first one I calculate that soon it is implemented in the rigorous method for separation of multicomponent in multistage, employee the method of bubble point, which gives I number of stages, taking the considerations made in the references bibliographies, which it gives therefore a deviation very pronounced when increasing I number of stages, taking the considerations made in the references bibliographies, from the components of the mixtures that put a noticeable separation in the values of the balance constant, took compounds of the same family to avoid this disadvantage, but the deviation even persists.

Although it is very brief east I outlined of my problem I hope that you can help me, in little that, I have understood that the Method of Muller but is recommended but nonstory with this information, and with respect to method BP for the distillation it is not specified to that conditions determine enthalpy.


Thanks.

RE: Help Me.... SRK for Method BP

Juan, (I am asking Juan to write his question in Spanish.)
Siento mucho pedirte que me expreses tu problema en Español. Yo me perdi leyendola en Ingles, por que esta un poco confusa de la manera que la expresastes. Escribeme a arbues@jorsm.com .

Sirva el actual para saludarle, y el encarecidamente para pedir a usted toda la ayuda que puede ofrecerme referente al método
de determinación del punta de burbuja y rocío.

El cuál a ser puesto en práctica en un modesto programa que e diseñado con el objetivo de determinar el punto de burbuja y de rocío, y luego de hacer una comparación, obtenemos un considerable porcentaje de error cuando comparamos con él con flash a punto de burbuja y rocío empleando en el Pro-II, esta desviación es del orden de 1. 5% del error relativo. En ambos casos se aplica ecuación estado Soave-Redlich-Kwong, para determinar las propiedades termodinámicas requeridas en dicho algoritmo.

Mi duda radica esencialmente. Si el error arrogado es por la ecuación de estado?. Si es como se puede corregir.?, donde puedo obtener dicho información.?...o si el el Algoritmo...Existe otro algoritmo ?... Cuál es?.. donde puedo conseguir información sobre él.?

Todo esto, solo es un preámbulo para el verdadera aplicación de este algoritmo, ya que el punto de burbujas, como las información que arroja sobre las condiciones termodinámicas que brinda serán empleadas en el método riguroso de destilación planteada por Wang-Henke, en el cual e error proveniente de punto de burbuja, tales como la Entalpía, Composición, constate de equilibrio, y temperatura repercuten fuertemente en el método riguroso.

Mi preocupación se basa que debo minimizar estos errores esencialmente de la Entalpía y de la temperatura que son los valores que influyen mayormente en los cálculos de la destilación rigurosa.

I think I could help you but you should repeat your question in a better English. I can also understand Spanish.
