【題組】 (2) What are the production rates of the overhead and bottom products after the tuning to the new reflux ratio ?
Problem 7
A chemical engineer designs a continuous unit for separating a liquid feed with a flow rate of 200 kg/min. The compositions (in weight percentage, wt%) of the feed are constant with time: 50.0 wt% of Component A, 48.0 wt% of Component B, 1.5 wt% of Component C and 0.5 wt% of other traceable components (denoted as Component D). A fractionation distillation column is employed for this separation, and the target composition of the overhead product, as collected by a total condenser, is 95 mol% of Component 'A and the target composition of the bottom product is 95 mol% of
Component B.
The molecular masses of Component A, B and C are 100 g/mol, 150 g/mol and 32 g/mol, respectively. Component D is mainly CH2O with an estimated molecular mass of 30 g/mol. Knowing that Component C and Component D are relatively more volatile than Component A and B, the engineer chooses to use a flash distillation to completely remove Component C and D prior to the fractionation distillation column. The equilibrium data, based on a binary system of Component A and Component B, are
summarized in a record book, showing the temperatures of bubble points are 120 ℃,110 ℃, 100℃, 90℃, 85 ℃ and 80 ℃ when the molar fractions of A (xA) are 0, 0.2,0.4, 0.6, 0.8 and 1.0, respectively. The temperatures of dew points are 120 ℃, 115 ℃,110 ℃, 100 ℃, 95 ℃ and 80 ℃ when the molar fractions of A (xA) are 0, 0.2,0.4, 0.6,0.8 and 1.0, respectively.
Please provide your answers to the followings:
(c) Continued on (b): Due to the demand from the customer, the chemical engineer further increases the targeted molar concentration of the Component A to be 98% in the overhead product by increasing the reflux ratio. The target composition in the bottom product is the same (i.e., 95 mol% of Component B).

二、建築設計部分：
⑴尊重生態環境與保存歷史文化，已經是廿一世紀的建築師的專業責任了，建築設
計正是表現建築師對這方面的知識、專業、以至於做為一個專業者的基本素養。
以下的題目是台灣社會中的真實基地，但是為了做為考題，我們加入了一些假設
條件，為的是測試應考者對環境的敏感度與相應的建築設計能力。
在前述的建築計畫書的基礎上，今要求建築師提供一能表達構想，與業主能溝通
的「建築設計構想圖」（schematic design）。
⑵試繪建築設計構想圖（基地面積及比例尺可自訂，未提供之測繪圖可假設與已經
提供之圖面類似），此設計圖須包括下列各項：（70 分）
【題組】剖面圖或是剖面透視圖、投影圖。
