従って、内部冷却器１４及び中和混合器１６の容器壁に要する機械的強度は小さいので、内部冷却器１４及び中和混合器１６の容器壁は薄くて済み、経済的である。
With the configuration described above, in the present embodiment, the pressure of the reaction product in the
Therefore, since the mechanical strength required for the container walls of the internal cooler 14 and the neutralizing
