An approach to obtain Heat Integration scheme with higher viability for complex system

Chen, Xiaohui; Zheng, Danxing; Chen, Juan - In: Energy 78 (2014) C, pp. 720-731

Focused on the problem of low viability of Heat Integration (HI) scheme for complex system, a strategy and a method of hierarchical Heat Integration (HHI) were proposed in this paper. The practical limitations and energy target were combined stage by stage to determine the number of hierarchy...

Targeting and design of CWNs (cooling water networks)

Shenoy, Akshay U.; Shenoy, Uday V. - In: Energy 55 (2013) C, pp. 1033-1043

CWNs (cooling water networks) are targeted and designed in this work by an analytical approach requiring no graphical procedures. The key basis for the approach is the conversion of the cooling duties to equivalent inlet–outlet (demand–source) pairs. The UTA (Unified Targeting Algorithm) is...

Applying exergy and total site analysis for targeting refrigeration shaft power in industrial clusters

Hackl, Roman; Harvey, Simon - In: Energy 55 (2013) C, pp. 5-14

Process cooling below ambient temperature is an energy demanding part of many chemical production processes. Compression refrigeration systems operating at very low temperatures consume a lot of high quality utility such as electricity or high pressure steam to drive the compressor units. In...

A double-pinch criterion for regenerative Rankine cycles

Zebian, Hussam; Mitsos, Alexander - In: Energy 40 (2012) 1, pp. 258-270

A double-pinch criterion for closed feedwater heaters (FWH) of regenerative Rankine cycles is presented. The FWHs are modeled as counter-current heat exchangers. Thus, two potential pinch positions in the FWH exist: (i) at the exit of the bleed (drain) and (ii) at the onset of condensation. For...
