Abstract:
This work presents a mathematical model for retrofitting the steam power plants in a refinery site. This problem is formulated as a mixed-integer nonlinear program (MINLP). Feasible retrofit alternatives suggested by experienced field engineers are investigated in sequence to examine the saving of those possible modifications. Furthermore, techno economic simulation of water and energy recovery systems from boiler flue gasses has been examined to obtain the optimal condition of these systems. For heat recovery, a systematic model for using organic Rankine cycle has been developed and results showed that toluene is the best possible working fluid in this case. Finally, water absorption cycle with ethylene glycol has been simulated and results showed that up to 75 present of water vapor could be recovered
