Cascaded Organic Rankine Cycles (ORCs) for Simultaneous Utilization of Liquified Natural Gas (LNG) Cold Energy and Low-Temperature Waste Heat

This scenario has the highest potential for energy efficiency improvement since it will benefit from waste heat recovery by the steam cycle and gas turbines efficiency increase

ORC performs better than the CO 2 cycle for LNG cold energy utilization since organic working fluid can condensate at a much lower temperature, while the transcritical CO 2 cycle

In an organic Rankine cycle, there are generally two ways to increase the net power output, namely increase thermal efficiency and increase the amount of waste heat recovered

Heating performance efficiency of the Trombe wall system based on the (a) stored energy, and (b) natural convection heat transfer

The working fluids with higher critical temperature show better ability to recover waste heat and the working fluids with lower critical temperature show higher ability

Parameters related to incoming waste, such as transport of food waste and DM share of incoming waste, had a significant impact on both the energy efficiency and environmental benefit

The heat integration between ORC streams and heat sources/heat sinks is optimized with the methodology proposed by Kalitventzeff and Maréchal (1999), which determines the maximum
