RECOVERY OF LOW-TEMPERATURE WASTE HEAT AND LNG COLD ENERGY

This paper has proposed a combined power system, in which low-temperature waste heat can be efficiently recovered and cold energy of liquefied natural gas (LNG) can be fully utilized as well. The generation of electric power using the Organic Rankine Cycle appears the most practical. It is found that less energy in the low-temperature waste heat can be converted to the power by organic Rankine cycle because boiling essentially take place at constant pressure and temperature in the evaporator.
