An apparatus and method are provided for containing particulate material e.g.: spent catalyst when evacuating an industrial reactor vessel used in hydrocarbon processing. A containment bag (3) isprovided one end of which is located adjacent the wall of the reactor housing (1) about an outlet (2) thereof. The bag (3) has a panel defining side walls (4, 5), and a top wall (6) and an end panel (7) and assumes a generally cuboid shape when inflated in use. A barrier wall (22) may be constructed in the vicinity of the outlet (2) to provide additional containment. In one embodiment, a vent outlet G is defined in the region adjacent the vessel outlet to permit venting of steam and air whilst discharged particulate material is contained within the bag. |
