   Sammanfattning : The process industry is responsible for a significant share of the final industrial energy use in Sweden. In particular, the pulp and paper industry accounts for more than 50 %. In this context, a number of studies have shown that there is a substantial potential for energy savings in the pulp and paper industry. LÄS MER

5. 4. Process Utility Performance Evaluation and Enhancements in the Traditional Sugar Cane Industry

   Författare :Eyerusalem Deresse Birru; Andrew Martin; Catharina Erlich; Hailong Li; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sugar cane; energy saving; heat loss; steady state; transient state; CO2 emission; absorption chiller; pellet; bagasse drying; energy perfor-mance; traditional mills; modern mills; waste water; surplus power; Energy Technology; Energiteknik;

   Sammanfattning : The need to achieve sustainable development has led to devising various approaches for the efficient utilization of natural resources. Renewable energy technology and energy efficiency measures feature prominently in this regard, and in particular for industries such as sugar production:  the sugar cane industry’s eponymous feedstock is a renewable resource, and mills have potential for increased energy savings via improvements to cogeneration units, electric drive retrofitting, and other measures.
