IIR GL2020 conference: Range of CO2 applications
Almost half of the presentations at the IIR Gustav Lorentzen conference in Kyoto focused on CO2, in commercial refrigeration systems but also in many other applications. Overview of these...
IIR Rankine Conference 2020: Which alternative working fluids for ORC systems?
HFOs (hydrofluoroolefins), HCFOs (hydrochlorofluoroolefins) and hydrocarbons were the main alternatives to HFC245fa presented during the IIR Rankine Conference 2020.
Latest progress of the LNG industry in Africa
Africa is expected to increase its share of LNG production by 2050. Emerging infrastructures and gas-specific regulations suggest that the region will become a major LNG hub.
