Production process design using Multi-Criteria Analysis
Treitz, Martin - 2006
Intra- and inter-company production networks have gained increased importance in developed and industrialising countries. By reusing waste of industrial sites as a valuable input within the production network, material cycles can be closed and resource efficiency can be improved.In order to...

Targeting and design of chilled water network
Foo, Dominic C.Y.; Ng, Denny K.S.; Leong, Malwynn K.Y.; … - In: Applied Energy 134 (2014) C, pp. 589-599
Chilled water is a common cooling agent used in various industrial, commercial and institutional facilities. In conventional practice, chilled water is distributed via chilled water networks (CHWNs) in parallel configuration to provide required air conditioning and/or equipment cooling in the...

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...

Process integration in bioprocess indystry: waste heat recovery in yeast and ethyl alcohol plant
Rašković, P.; Anastasovski, A.; Markovska, Lj.; Meško, V. - In: Energy 35 (2010) 2, pp. 704-717
The process integration of the bioprocess plant for production of yeast and alcohol was studied. Preliminary energy audit of the plant identified the huge amount of thermal losses, caused by waste heat in exhausted process streams, and reviled the great potential for energy efficiency...
