Abstract
(EN)
A dispersing plate is provided in a fluidized bed reactor in which hydrate particles are kept in a fluid state by a hydrate forming gas introduced from below. The upper part in the dispersing plate functions as a fluidized bed part, and the lower part in the dispersing plate functions as a fluidizing gas introducing part. Further, a hydrate particle discharge port is provided in the dispersing plate, and a takeout conveyor is provided below the hydrate particle discharge port. Differential pressure detection means for detecting the differential pressure between the fluidized bed part and the fluidized gas introduction part is provided in the fluidized bed reactor. When the pressure in the fluidized bed part has become higher than the pressure in the fluidized gas introduction part, the rotation speed of the takeout conveyor is increased. On the other hand, when the pressure in the fluidized bed part has become lower than the pressure in the fluidized gas introducing part, the rotation speed of the takeout conveyor is lowered.

La présente invention concerne une plaque de dispersion installée dans un réacteur à lit fluidisé, dans lequel les particules d'hydrate sont conservées à l'état fluide à l'aide d'un gaz, formant de l'hydrate, introduit par en dessous. La partie supérieure de la plaque de dispersion sert de partie lit fluidisé et la partie inférieure de la plaque de dispersion sert de partie introduisant un gaz fluidisant. En outre, un orifice d'évacuation de particules d'hydrate est disposé dans la plaque de dispersion et un transporteur de sortie est installé sous l'orifice d'évacuation de particules d'hydrate. Les moyens de détection de pression différentielle, destinés à détecter la pression différentielle entre la partie lit fluidisé et la partie introduction de gaz fluidisé, sont placés dans le réacteur à lit fluidisé. Lorsque la pression se trouvant dans la partie lit fluidisé dépasse la pression présente dans la partie introduction de gaz fluidisé, la vitesse de rotation du transporteur de sortie augmente. En revanche, lorsque la pression se trouvant dans la partie lit fluidisé descend en dessous de la pression présente dans la partie introduction de gaz fluidisé, la vitesse de rotation du transporteur de sortie baisse.

 ハイドレート粒子が下方から導入されたハイドレート形成ガスによって流動状態に保持される流動層反応器に分散板を設け、該分散板の上方を流動層部とし、その下方を流動化ガス導入部とし、更に、前記分散板にハイドレート粒子払出し口を設けると共に、該ハイドレート粒子払出し口の下方に取出しコンベアを設け、且つ、前記流動層反応器に前記流動層部と流動化ガス導入部との差圧を検出する差圧検出手段を設け、流動層部の圧力が流動化ガス導入部の圧力よりも高くなった時は前記取出しコンベアの回転速度を上げ、流動層部の圧力が流動化ガス導入部の圧力よりも低くなった時は前記取出しコンベアの回転速度を下げる。
