Energy-use analysis and evaluation of distillation systems through avoidable exergy destruction and investment costs
Wei, Zhiqiang; Zhang, Bingjian; Wu, Shengyuan; Chen, Qinglin - In: Energy 42 (2012) 1, pp. 424-433
exergy analysis and an exergoeconomic evaluation to identify the potential energy savings in distillation processes. Methods … for calculating the avoidable/unavoidable exergy destructions and investment costs for distillation columns, and hot …-utility/cold-utility heat exchangers are proposed. For a distillation column, the unavoidable exergy destruction is estimated through the …

Analysis and characterization of an optical fiber for Carrol–Water liquid pair
Basurto-Pensado, M.A.; Romero, R.J.; … - In: Energy 36 (2011) 7, pp. 3952-3958
A system of energy recovery depends on the process operation conditions from which it receives the energy when a Carrol–Water pair is used. To improve the performance of the energy recovery system, the variables of temperature, pressure and concentration must be in balance. External sensors...
