Reference no: EM13938536

You are invited as an engineer to perform a study for a newly built community to cover their power need of 30 MW. You are told that there are two options for you to consider: (a) a natural gas fueled steam (actual Rankine cycle based) power plant and (b) a hot geothermal water (at 190^oC) driven isobutane Rankine power plant. You are now requested to study these two systems energetically, exergetically, environmentally and economically to make recommendations.

1) Follow the following procedure:

Design both power plants (by considering example 10.2 and problem 10.25)
Make problem statement
Show the cycles on a T-s diagrams with respect to saturation lines
Make CONCEPTUALLY CORRECT assumptions and approximations for each plant
Identify physical laws (FLT or SLT)
List properties in the table for each plant based on the state points
Write balance equations (mass, energy, entropy and exergy)
Do calculations through EES software for all mass flowrates, heat and work rates, efficiencies for all components and the entire system
Discuss results (with reasoning and verification)
Make recommendations on how to improve the efficiency.

2) Perform a comparative cost assessment for both power plants by considering the energy resources.

3) Perform a comparative environmental impact assessment for both power plants by considering the energy resources.

4) Prepare a report for submission (one per group).
