This is an open-book. closed-notes exam. To receive full credit on these problems you need to use the problem solving methods presented in the text and used in class. You must also clearly label all equations that you write and identify your answers by drawing a box around them. Ethylene glycol (EG) is produced by the reaction between ethylene oxide (EO) and water C_2H_4O + H_2Orightarrow C_2H_6O_2 Ethylene glycol can further react with ethylene oxide to form diethylene glycol (DEG)...

Problem #1: Haber-Bosch process. The Haber-Bosch process is an equilibrium-limited catalyzed reaction that converts nitrogen (N2) and hydrogen (H2) into ammonia (NH3). The process won Haber a Nobel Prize since it provided a way to produce fertilizer for millions of people at the beginning of the 20th century. However, this process typically has very low single pass conversion due to a low equilibrium at the prevailing temperature and therefore a recycle stream is required to achieve a high overall conversion....

Problem 1 An absorber-stripper process is used to remove carbon dioxide (CO2) and hydrogen sulfide (H2S) from a feed (stream 1) consisting of 25% CO2 and 15% H2S in nitrogen. In the absorber, a solvent selectively absorbs hydrogen sulfide and carbon dioxide. The absorber overhead (stream 2) contains only 2% CO, and the balance Nitrogen with no Hys. Ny is insoluble in the solvent. The rich solvent stream leaving the absorber (stream 3) is flashed in a flash separator: the...

This assignment is for my Engr dynamics systems class.
Consider the electromechanical dynamic system shown in Figure 1(a). It consists of a cart of mass m moving without slipping on a linear ground track. The cart is equipped with an armature-controlled DC motor, which is coupled to a rack and pinion mechanism to convert the rotational motion to translation and to create the driving force for the system. Figure 1(b) shows the simplified equivalent electric circuit and the mechanical model...

(1 point) Consider the two tank apparatus shown in the figure. Each tank has capacity 750 liters and initially contains 150 liters of fresh water. At time t = 0, the well-stirred mixing process begins. Suppose that the concentration of brine flowing into Tank 1 via the top tube is 0.75 kilograms per liter, and that the flow rates are r = 13 = 3 liters per minute, and r2 = 14 = 10 liters per minute. (a) Determine the...

how to do this problem
An Extraction-Distillation Process A mixture containing 50,0 wt% acetone (A) and 50.0 wt% water (W) is to be separated into two streams-one rich in acetone and the other in water. The separation process consists of extraction of the acetone from the water into methyl isobutyl ketone (MIBK or M), which has a much higher affinity for acetone than it does for water. The process is shown schematically below. M (solvent) M (solvent) Feed Raffinate 1...
