Abstract: The tank type container of the present invention comprises a long, horizontally placed, drum-shaped tank 3 and a parallelopiped container frame 5 surrounding the tank 3. The tank 3 is provided with a charging tube 20 at the top of the longitudinal front end, a discharging tube 21 at the bottom of the longitudinal back end, and, at the outside, an air-supplying apparatus for supplying compressed air into the tank to discharge polycarbonate resin pellets. The tank 3, the charging tube 20, the discharging tube 21 and the air-supplying apparatus are accommodated in a space surrounded by the container frame 5. The container frame 5 is provided with metal fitting members 6 for locking engagable with a locking mechanism possessed by the bed of a trailer. Therefore, the present tank type container is usable as a large-capacity container for land transportation and sea transportation, allowing for improved efficiency in transportation of polycarbonate resin pellets.

Abstract: Fine particles which electrostatically adhere to synthetic resin pellets are separated from the pellets by bringing the pellets/fine particles mixture into contact with an ionized gas. The ionized gas eliminates the electrostatic adhesion between the synthetic resin pellets and the fine particles. The resulting fine particles may thereafter be readily separated from the pellets and the freed fine particles may be withdrawn in a gas stream. Removal of the fine particles to less than 40 ppm is possible. Apparatus for carrying out the method is also described as is a system for stocking synthetic resin pellets using the described apparatus.
