Maximising Cold Energy: Innovating In LNG Regasification Efficiency
During production, natural gas undergoes compression and chilling to convert it into LNG, primarily to reduce its volume for easier transportation. LNG is transported in insulated cryogenic ship tanks at atmospheric pressure, requiring cooling to approximately -160°C at 1 atm. Around 500 kWh/t of LNG is needed for compression and refrigeration, making cold energy exploitation thermodynamically appealing. Currently, less than 1% of this potential is utilised.
In this white paper, Exergy explores how ORCs can efficiently harness the cold energy potential in LNG while facilitating natural gas regasification. The white paper outlines the advantages of LNG regasification through ORCs compared to conventional technologies and introduces Exergy’s patented innovation: an ORC-based Cold Energy Plant that achieves high efficiency using the proprietary Exergy Radial Outflow Turbine combined with a Multilevel Condensation Cycle.
The company also presents the advantages of Exergy’s new solution over traditional ORC systems employed for cold energy recovery, along with a practical case study from a 1 million tpy LNG regasification plant, highlighting significant improvements in power production and the estimated reduction in carbon dioxide emissions.
