Low-grade heat conversion into power using organic Rankine cycles – A review of various applications

Nowe materiały i procesy w konwersji oraz przechowywaniu energii – wybrane zagadnienia

“…Różne zastosowania organicznego cyklu Rankine'a (ORC) zagospodarowujące niskotemperaturowe ciepło przedstawiono w artykule [53]. W kolejnych publikacjach zostały omówione czynniki robocze i wybór ekspandera [2] oraz techniczno-ekonomiczna analiza [48] dla ORC.…”

Organic Rankine cycles in waste heat recovery: a comparative study

“…Although the idea of using waste water injection brine is relatively new, ORCs driven by geothermal heat are well researched and are in commercial operation, as summarized by Tchanche et al [6]. Nguyen et al [11] studied a typical North Sea oil and gas platform.…”

“…The fluids modelled are dry or isentropic, as recommended by Tchanche et al [6]. Dry fluids have a positive vapour saturation curve, whereas isentropic fluids have a vertical saturation curve.…”

“…Tchanche et al [6] present a review of ORCs by application. The technical differences of ORC systems and the maturity of existing ORCs are assessed for each application.…”

Power Generation Targets from Hot Composite Curves

“…Low to medium temperature heat source streams can be found in many systems including industrial processes, geothermal energy, biomass, and solar energy [4]. Particularly in the processes of the basic materials industries, many heat source streams exist that transfer excess heat into cold utilities such as cooling water or air at different temperatures.…”
