**Problem P2.70:**
In petroleum refining, crude oil is separated into several different mixtures of hydrocarbons. One product stream is called the light alkanes, which contains mainly methane, ethane, propane, butane, and pentane. In one facility, the light alkane stream [1000 kgmol/h, 10 mol% methane (M), 30 mol% ethane (E), 15 mol% propane (P), 30 mol% butane (B), and 15 mol% isopentane (I)] is processed to produce five different product streams. The separation is done in a series of distillation columns, as shown.
Stream flow rates:
- Stream 4: 40 kgmol/h
- Stream 6: 100 kgmol/h
- Stream 11: 300 kgmol/h
Complete a DOF (Degrees of Freedom) analysis. Calculate flow rates and compositions of all process streams. Report your results in both mole and mass units, using a table format, with stream numbers as column headings and components as row headings.
**Diagram Explanation:**
This process diagram represents the separation of a mixture into multiple components using a series of mixers and separators.
- **Stream Inputs and Outputs:**
- **Stream 1:** Enters Mixer with components M, E, P.
- **Stream 2:** Outputs from Mixer to Separator with components M, E, P.
- **Stream 3:** Exits Separator leading to another Separator with P, B, I.
- **Stream 4:** Provides flow at P exiting a separator.
- **Stream 5:** Enters a Separator from another separator with M, E, P.
- **Stream 6:** Outputs from Separator containing M, E with 0.5% additional component.
- **Subsequent Streams:**
- **Stream 7:** With components M, E, P leading into another Separator.
- **Stream 8 and 9:** Outputs containing M, E, P with 2% and E with 1%, P with an additional component respectively.
- **Stream 10:** Branches off a Separator with P, B, I components.
- **Stream 11:** Outputs B, I from Separator leading to another Separator.
- **Final Streams:**
- **Stream 12:** Final](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff4dfc165-1571-419f-99fc-a4587d76c340%2F2b498e9b-1b01-45ac-b7d2-d0523503b9f1%2Fkhtxr8a_processed.png&w=3840&q=75)
