発の大幅な抑制が可能である。Here, the generated gas rises in the raw material liquid as bubbles, passes through the gas permeable membrane, and is taken out from the outlet IA to the outside of the reaction tank. Evaporation of the raw material liquid occurs only at the rising bubble interface. In conventional equipment, the surface of the raw material liquid is in contact with the gas phase, so the evaporation of the raw material 2-propertool is
This occurs on the surface of the raw material liquid and on the surface of bubbles in the liquid. Since the pressure inside the bubble in the liquid is higher than in the surrounding area, evaporation on the surface of the raw material liquid is much greater than evaporation between the bubble and the surface. On the other hand, in the device of the present invention, the gas permeable membrane acts as a wall when viewed from the liquid (therefore, the only interface where the liquid can evaporate is the surface of the bubbles in the liquid generated by the reaction, making it possible to significantly suppress evaporation. It is.

Since the heat lost due to raw material evaporation is reduced, thermal efficiency can be significantly improved.
