To find the heat given to the feed for the flash vaporization process, we can use the following formula:
Heat given = (Residue / (Residue + Distillate)) * Enthalpy of Feed
Given:
Residue to Distillate ratio = 0.65
Enthalpy of Feed = 500 KJ/kmol
Enthalpy of Distillate = 800 KJ/kmol
Enthalpy of Residue = 200 KJ/kmol
Feed rate = 100 kmol/hr
Calculating the heat given:
Residue = Residue to Distillate ratio * Distillate
Residue = 0.65 * 800 KJ/kmol = 520 KJ/kmol
Heat given = (520 KJ/kmol / (520 KJ/kmol + 800 KJ/kmol)) * 500 KJ/kmol
Heat given = (520 KJ/kmol / 1320 KJ/kmol) * 500 KJ/kmol
Heat given = 0.3939 * 500 KJ/kmol
Heat given = 196.95 KJ/kmol
To find the total heat given to the feed, we need to multiply the heat given per kmol by the feed rate:
Total heat given = Heat given * Feed rate
Total heat given = 196.95 KJ/kmol * 100 kmol/hr
Total heat given = 19695 KJ/hr
Converting the heat given to KJ:
Total heat given = 19695 KJ/hr * (1 hr / 3600 s)
Total heat given = 5.47 KJ/s
Therefore, the heat given to the feed for the flash vaporization process is approximately 5.47 KJ/s.
The correct answer is option 'C' - 6363 KJ.
Note: There seems to be an error in the question options, as none of them match the correct answer. The correct answer should be approximately 5.47 KJ/s, not 6363 KJ.
Heat given = (Residue / (Residue + Distillate)) * Enthalpy of Feed
Given:
Residue to Distillate ratio = 0.65
Enthalpy of Feed = 500 KJ/kmol
Enthalpy of Distillate = 800 KJ/kmol
Enthalpy of Residue = 200 KJ/kmol
Feed rate = 100 kmol/hr
Calculating the heat given:
Residue = Residue to Distillate ratio * Distillate
Residue = 0.65 * 800 KJ/kmol = 520 KJ/kmol
Heat given = (520 KJ/kmol / (520 KJ/kmol + 800 KJ/kmol)) * 500 KJ/kmol
Heat given = (520 KJ/kmol / 1320 KJ/kmol) * 500 KJ/kmol
Heat given = 0.3939 * 500 KJ/kmol
Heat given = 196.95 KJ/kmol
To find the total heat given to the feed, we need to multiply the heat given per kmol by the feed rate:
Total heat given = Heat given * Feed rate
Total heat given = 196.95 KJ/kmol * 100 kmol/hr
Total heat given = 19695 KJ/hr
Converting the heat given to KJ:
Total heat given = 19695 KJ/hr * (1 hr / 3600 s)
Total heat given = 5.47 KJ/s
Therefore, the heat given to the feed for the flash vaporization process is approximately 5.47 KJ/s.
The correct answer is option 'C' - 6363 KJ.
Note: There seems to be an error in the question options, as none of them match the correct answer. The correct answer should be approximately 5.47 KJ/s, not 6363 KJ.
