A systematic Design Methodology for Multicomponent Membrane Systems
Bamigbetan, Opeyemi Olayinka (Master thesis, 2015)Abstract Fossil fuel predominantly dominates the world energy supply. With energy demand set to increase, especially for developing countries, CO2 emissions tax and the environmental impact of high CO2 concentration in ... -
Experimental investigation of the performance of a hydrocarbon heat pump for high temperature industrial heating
Bamigbetan, Opeyemi Olayinka; Eikevik, Trygve Magne; Nekså, Petter; Bantle, Michael; Schlemminger, Christian (Chapter, 2018)A 20 kW heat pump test rig has been built to investigate and validate heat delivery up to 110 °C using a vapour compression cycle. The heat pump is a cascade cycle with propane as the working fluid in the low temperature ... -
High temperature industrial heat pumps utilising natural working fluids
Nekså, Petter; Bantle, Michael; Schlemminger, Christian; Bamigbetan, Opeyemi Olayinka (Chapter, 2019)There is a large demand for heat typically in the temperature range 100-200⁰C in different industries. This is today often covered by fossil fuel burning or direct use of electricity. Heat pumps has to a lesser extent been ... -
Performance of high temperature heat pump for simultaneous and efficient production of ice water and process heat
Schlemminger, Christian; Svendsen, Eirik Starheim; Foslie, Sverre Stefanussen; Bantle, Michael; Bamigbetan, Opeyemi Olayinka; Nekså, Petter (Chapter, 2019)Industrial processes like milk production often require simultaneous cooling and heating at temperature of 1 °C to 10 °C and 90 °C to 120 °C, respectively. High temperature heat pumps (HTHP) with natural working fluids are ... -
Review of Vapour Compression Heat Pumps for High Temperature Heating using Natural Working Fluids
Bamigbetan, Opeyemi Olayinka; Eikevik, Trygve Magne; Nekså, Petter; Bantle, Michael (Journal article; Peer reviewed, 2017)The use of high temperature heat pumps (HTHPs) operating with natural fluids has been shown to be a potential environmentally friendly solution to increase energy efficiency in industrial processes. Industrial processes ... -
The development of a hydrocarbon high temperature heat pump for waste heat recovery
Bamigbetan, Opeyemi Olayinka; Eikevik, Trygve Magne; Nekså, Petter; Bantle, Michael; Schlemminger, Christian (Journal article; Peer reviewed, 2019)Waste heat is an abundant resource that if recovered with a heat pump would increase energy efficiency in industrial processes. This will provide improvements in heat utilization and reduce the environmental impact of ... -
Theoretical analysis for charge reduction in a 200 kW hydrocarbon hight temperature heat pump
Bamigbetan, Opeyemi Olayinka; Eikevik, Trygve Magne; Nekså, Petter; Bantle, Michael; Schlemminger, Christian (Chapter, 2018)Hydrocarbons with thermodynamic properties similar to synthetic fluids are alternative working fluid for high temperature heat pumps without the negative environmental impact of greenhouse gases. Though hydrocarbons have ...
