Subject:
CHEG 200 Project P3, due Monday, Mar. 26 at 1:00 p.m.
For Project P3, your team is to solve the six (or seven) problems given below. The memo of 18
January 2012 on the “CHEG 200 Internship Program” contains an attachment on team projects, which
addresses your responsibilities for completing the HYSYS problem, the four (or five) analysis problems,
and the laboratory problem in a team project. Your team must work cooperatively on these problems and
submit a team report. Please provide the problem solution summary for only Problems P3.A3 and P3.A4,
and attach all the worked out solutions for the assigned problems herein, per the guidelines give in
Appendices A to E of the provisional engineer handbook on the Development of an Engineering Project.
As a provisional chemical engineer in BEEF, Inc., you are expected to apply the company’s
documentation standards and practice professionalism.
For the first Monday of Project 3, your team is to complete the “Purpose” and “Equipment” parts and
have the conceptual and mathematical models of your assigned experiment in your laboratory notebook.
Please consult the electronic version of the “Encyclopedia of Chemical Engineering Equipment” for a
general description of your equipment. Also, your team members are to complete for the first Monday,
to the fullest extent possible, the conceptual model diagrams for Problems A1 to A4 (or A5). Randomlyordered diagram templates are available in the Blackboard CHEG 200 course.
Problem P3.H3
Using your assigned reactor inlet temperature as provide in the attachment, you are to complete
Problems SM.1 and SM.2 that appear in the blue manual entitled Chemical Process Simulation and
the Aspen HYSYS Software by Michael Hanyak. The first problem focuses on the reactor, the heart
of the process flowsheet that you will be developing, and the second problem looks at a cooler and
decanter. By the second Monday of this two-week project, each team member is to document
independently their HYSYS simulation for each of these SM problems in their project journal, per
the instructions given in each problem.
After all team members have independently documented these two problems, your team is to prepare
tables and graphs based on the reactor inlet temperatures and then answer the team questions, per the
instructions given in Problems SM.1 and SM.2. Your team’s documentation for these items
represents the solutions for the first two SM problems.
Problem P3.A1
A quantity of liquid chloroform is placed in an open, transparent, three-liter flask and boiled long
enough to purge all air from the vapor space. The flask is then sealed and allowed to equilibrate at
120°C. Visual inspection shows 100 mL of liquid chloroform present. What is the pressure in the
flask at equilibrium (explain your reasoning)? What is the total mass in grams of chloroform in the
flask? What fraction is in the vapor phase at equilibrium? Compare and contrast the answers to
these three questions using the ideal gas law, the Soave-Redlich-Kwong (SRK) equation of state,

Peng-Robinson Stryjek-Vera (PRSV) equation of state, and the law of corresponding states (Section
5.4b in the F&R textbook or the Lee-Kesler-Plocker equation of state in HYSYS). This problem addresses
the concepts of vapor pressure, the Antoine equation, and an equation of state for a pure component.
Problem P3.A2
Your team is to solve Problem 6.18 in the Felder and Rousseau textbook, 3rd Edition. You are also to
determine the dew-point temperature of the entering air. This problem addresses the concepts of
relative humidity and Raoult’s Law for a one condensable component.
Problem P3.A3
Hawbawg Chemical Co. wants to produce a new chemical insecticide to get rid of those annoying
gnats in the summer. The chemical is called ‘gnatBgone’ and has the following properties:
BCF = 3105, solubility = 0.3 ppm, KOC = 103
Hawbawg wants to discharge the waste stream from the process directly into the Susquehanna River
at a flow rate of 50 kg/day. The waste stream is 1% ‘gnatBgone’ by weight. The river flow rate is
300L/min, the fish density is 0.5 g / 1000L, and the suspended carbon concentration is 1g C / 1000L.
Once the river comes to steady-state, Hawbawg wants to know what is the mass composition of
‘gnatBgone’ in the river in ppm? What are the mass ratios of ‘gnatBgone’ in the water, fish,
suspended carbon (i.e., floating soil), and any other source? For some insight, see Pages 6-5 to 6-7
and 6-58 to 6-63 in the CinChE manual.
If Hawbawg were to use chrysanthemic acid instead of ‘gnatBgone’ as the insecticide, what would the
mass ratios be for the same discharge and river conditions? Use EPI Suite to obtain necessary
environment partitioning coefficients for chrysanthemic acid.
Problem P3.A4
Your team is to solve Problem 6.60 in the Felder and Rousseau textbook, 3rd Edition. This problem
addresses the concepts of distillation and Raoult’s Law for a binary system. The eLEAPS problem
session “P03 Distillation” provides valuable insights to help you solve Problem 6.60.
Problem P3.A5
Your team is to solve Problem 6.37 in the Felder and Rousseau textbook, 3rd Edition. This problem
addresses the concepts of atom balances and Raoult’s Law for a one condensable component.
Problem P3.L3
For Projects 2, 3, 4, and 5, your team will rotate through four laboratory experiments. For the current
project, the laboratory assignments are as follows:

For each experiment, the laboratory problem can be found in the Blackboard CHEG 200 course.
Also at this site, you can find a general description for the objectives of the laboratory experiments.
Your team must maintain a lab notebook for these experiments, and you must dress appropriately for
the lab. Your team can not enter the lab without a proper lab notebook or appropriate dress.
Final Remarks
If you have any questions or concerns about this project assignment, please contact your project
supervisors for further clarification. We conclude this memo with suggested readings, required
exercises, suggested quizzes, and suggested practice problems. You are encouraged to consult with your
teammates as you do these activities, but you must independently-document (ID) the second and third
activities, which are called ID items. This documentation must be contained in your technical journal.
