Name: SR-Code: Section: Date: ChE 414 – Separation Process (EXERCISES NO. 1) 1.A. HENRY’S LAW Kanchou’s Valentine’s day took an unexpected turn when Luna rejected his confession during their date. Upon returning home, disheartened by the turn of events, he consoled himself that there’s no point in crying over spilled milk. Instead, he decided to make one pitcher of milk to drown all the bitterness away. During preparation while looking at the warm water, his chemical engineering instincts kicked in, prompting him to contemplate the composition of the liquid and gas phase for a mixture of air and the warm liquid water at 158 oF at 1 atm. Before he became consumed by the additional sorrow resulting from miscalculating the phase equilibrium problem he bothered himself with, help him solve the problem instead.
1.B. HENRY’S LAW
Working relentlessly on the previous problem for hours, Kanchou eventually drifted into sleep without even finishing what he’s supposed to do – drink milk. By the time he woke up, the warm water he had prepared had already cooled down to 293K and the barometer indicated a reading of 101.3 kPa. Filled with revitalized energy from oxygenated blood running through his veins , Kanchou, eager to to redeem himself from his previous setback, sets out to challenge himself once again. This time, to determine the mole fraction of oxygen in the now room temp water but exposed to dry air instead. Before solving the problem, he recalls that the Henry’s law constant for oxygen dissolved in water is 4.06 x 109 Pa (mole of O2 Per total mole solution) at 293K.
3. EQUILIBRIUM CONSTANT & RELATIVE VOLATILITY
Raiden Mei is someone with a long history of neglecting her own feelings and she was used to silently accepting her loneliness within the home. Despite still having a soft heart, she often put her guard up when people approached. It was only after Kiana Kaslana innocently bombarded her with requests for food (despite her lack of skill at the time) that she began to soften again. This would be the start of her love for cooking. For her cooking needs, Mei procures LPG Shiki-chan’s shop, where the typical components include propane, n-butane & isobutane. Intrigued by her curiosity, she desired to: a. Calculate the individual components’ equilibrium constant i. at 70oF and 2 atm (as ideal system) ii. at 70oF and 2 atm (using De-Priester Chart) b. Compute the relative volatility of propane and n-butane at the same above conditions / cases.
