Energy efficiency of hydrothermal gasification

Подпись: Fig. 4.5.2. Heat balance of hydrothermal gasification. For the ideal process as shown in Fig. 4.5-2, the energy efficiency of hydrothermal gasification is unity.

This is to be noted since misunderstanding that energy efficiency of hydrothermal gasification is low due to the large amount of heat required to attain hydrothermal condition. When heat recovery is properly made, a high energy efficiency is possible.

Energy efficiencies higher than 70% including electricity and heat loss at the heat exchangers have been shown by a detail process calculation.
