HYDRATE POST TREATMENT APPARATUS AND HYDRATE PARTICLE DIAMETER CONTROL METHOD

摘要

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.
