1. Organisk Rankine cykel i konfiguration med naturgasdrift.
M1-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)Sammanfattning : Organisk Rankine cykel är en förångningscykel med användningen av en organisk fluid för att få bättre lågtempererade egenskaper än vid användningen av vattenånga. Naturgas är ett bränsle som används inom industrin och sjöfarten, den förvaras mycket kallt i vätskeform för att spara utrymme. LÄS MER
2. Techno-Economic Analysis of Organic Rankine Cycles for a Boiler Station : Energy system modeling and simulation optimization
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The Organic Rankine Cycle (ORC) may be the superior cycle for power generation using low temperature and low power heat sources due to the utilization of high molecular mass fluids with low boiling points. They are flexible, simple, easy to operate and maintain, and offer many possible areas of applications including waste heat recovery and power generation from biomass, geothermal and even solar energy.

3. Thermoeconomic analysis of LNG physical exergy use for electricity production in small-scale satellite regasification stations
Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : Liquefied natural gas (LNG) cold utilization in small scale regasification stations is a novel topic in the industry, while such systems have been proven feasible in large scale LNG facilities. Cold recovery and utilization in LNG regasification facilities would increase the thermodynamic efficiency and reduce cold pollution. LÄS MER
4. Performance evaluation in post integrated organic Rankine cycle systems : A study on operational systems utilizing low grade heat
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Organic Rankine cycles can be integrated with district heating systems and in applications of biogas digestion. Evaluating the performance of the installations by Againity AB in Ronneby and Norrköping, Sweden, is a unique opportunity which can support the establishment of ORC technology in the waste heat recovery market, unveiling its feasibilities and limitations.

5. Perspectives for Power Generation fromIndustrial Waste Heat Recovery
Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This thesis work was carried out at Siemens in Germany in the department of Steam Turbines, and aims to raise awareness of the potential for broader deployment of waste heat recovery (WHR) from industrial processes for power generation. Technologies available to recover heat are presented and sorted out according to the features of the heat source. LÄS MER
