111 m3/min of hydrogen measured at normal conditions and nitrogen at a 300% excess enter an isobaric reactor. The inlet gases at 490°C are reacted in the presence of a catalyst to synthesize ammonia. The process has an efficiency of 33%. The exhaust gases are cooled to -40°C to condense the ammonia. Assume that the Cp of the gas phase species can be used in the temperature range, and that Cp NH3 (l) = 0.071938 kJ/mol K. Calculate the overall heat flow of the system in kW.

You have a hot gas that enters a pipe at 140c and ethylene entering the same pipe at 30 C to make an ethylene mixture.

I need to figure out equations for U (overall heat transfer coefficient) as a function of mass flowrate M and the exit temp of the ethylene as a function of mass flowrate.

How do you go about designing these equations?

Part 1. Getting to know your sedimentary rocks (40-50 min)

The lecture notes covered some basics of the textures and mineralogy used to name sedimentary rocks as well as information concerning the formation and transportation of sediments. In addition to this information you will also need the following to complete this part of the lab:

Mineral and rock set (plus the accompanying booklet for reference)

Rock and Mineral ID charts

Any other notes or textbook you want for reference

Couple of drops of vinegar

Mineral 19. Sandstone (although more appropriately referred to as Quartz Sandstone) and Mineral 21. Arkose

1. Both of these sedimentary rocks consist of sand sized grains cemented together. What is the major difference between them?

2. Given the difference noted in Q1, and your knowledge of chemical and mechanical weathering (refer to notes and textbook as needed), which of these two rocks had sediments that underwent a higher degree of weathering and transportation prior to lithification? Explain your reasoning.

Mineral 20. Shale

3. The sediment size in shales is {very large, large, medium, small, very small}. Choose one.

4. Given this grain size, and what you know about sediment transportation, what would the relative velocity of the water that deposited these sediments? (I don’t need an actual speed, just a general fast/slow/medium/etc.)        

5. Give an example sedimentary environment/location where the sediment that makes up this shale could have been deposited (refer to the textbook if you need some help with sedimentary environment examples).

Mineral 22. Conglomerate and Mineral 23. Breccia

6. Both of these sedimentary rocks can have the same wide range of clast size. What is the main difference between a conglomerate and a breccia? I.e. in looking at them both, how would you identify one vs. the other?

7. Given your answer in the question above, what does this imply about how far the sediments had travelled prior to being cemented into these rocks? Explain your reasoning. (hint: read about transportation and rounding in the textbook)

Mineral 24. Limestone (depending on your specific sample, this may or may not contain fossils)

8. Unlike the other sedimentary rocks in this rock set, this limestone is not a clastic sedimentary rock. What type of sedimentary rock is it?

9. What mineral is limestone composed of?

10. Because of the mineral composition of limestone, if you were to place a couple of drops of acid (HCl) on the limestone what should happen? (it may help you to refer to the mineral ID chart)

A fluid with constant viscosity and density flows in radial direction from R1 radius surface to R2 radius surface in the annular region, which consists of porous horizontal cylinders with coaxial R2 (outer) and R1 (inner) radii. (V = V (r)).

Make your simplifications using the continuity equation and motion equations by specifying your required assumptions.

Since the fluid is incompressible and is in laminar flow, obtain the steady pressure profile P(r) in terms of velocity in the outer radius vr(R2) and pressure P(R2) in the outer radius.

In the hydrodealkylation of toluene to produce benzene, a stream of toluene is mixed with a recycle stream and enters a reactor along with a stream of pure hydrogen. The reaction products at 530°C enter a condenser where they are cooled to 45.0°C. A vapor stream containing 0.55 mol CH4/mol leaves the process, and a liquid stream containing 0.75 mol benzene/mol and 0.25 mol toluene/mol enters a distillation column. The distillate of the column leaves the process at 800.0 mol/hr and contains 0.9000 mol benzene/mol and 0.1000 mol toluene/mol. The bottoms of the column contain 0.15 mol benzene/mol and 0.85 mol toluene/mol and is recycled back to the fresh feed. Hydrogen is fed into the process at 1850 mol H2/hr. This process is carried out at 760 mmHg. Draw the process flow diagram and describe (label) it fully by solving for the unknown variables for all the streams. Calculate the Single Unit and Overall Conversion (%) of toluene.
