LNG Cold Energy Recovery ASU
LNG Cold Energy Recovery Overview
Liquefied Natural Gas (LNG) releases significant low-temperature cold energy (-162°C, ~830 kJ/kg) during classification. Traditional vaporization methods waste this energy, while cold energy recovery technologies can improve energy utilization by 20%-40% and reduce thermal pollution.
LNG Cold Energy Recovery ASU
Principle of Cascading Cold Energy Utilization Matching LNG cold energy to demand scenarios by temperature gradients: a.Ultra-low temperature zone (-160°C~-100°C) Air separation, superconducting material production b.Mid-low temperature zone (-100°C~-50°C) Cold storage, dry ice manufacturing c.Low-temperature residual cold (-50°C~0°C) Cryogenic power generation, district cooling
