STORAGE AND TRANSPORTATION OF A CATALYST FOR A PRODUCTION OF OLEFIN POLYMERS

摘要

The present invention relates to a pressure drum (1) for filling, storing, transporting and discharging a catalyst (3) for a production of olefin polymers. The pressure drum (1) comprises a cylindrical body (7) with a first end (9) and a second end (11). Furthermore, the pressure drum (1) comprises a first torispherical head (13) and a second torispherical head (15). The first torispherical head (13) is arranged at the first end (9) of the cylindrical body (7) and the second torispherical head (15) is arranged at the second end (11) of the cylindrical body (7). The first torispherical head (13) and the second torispherical head (15) are connected to the cylindrical body (7) by full penetration welding in such a way that the pressure drum is adapted for withstanding pressures between-0,5 and 9 bar g.
