1. An addition system for introducing particulate material into an industrial process, said addition system comprising:
(a) a vessel for holding the particulate material, wherein the vessel has a top and a bottom;
(b) one or more weighing devices;
(c) a controller for controlling operation of the addition system;
(d) a base plate to support the vessel and optionally the controller; and
(e) three or more legs, each leg having an uppermost section that connects to the vessel and a foot that is connected to the base plate, wherein
the one or more weighing device are mounted on the base plate and support the legs of the vessel;
the widest diameter of the vessel is less than the diameter of a circle drawn through the feet of the legs;
the vessel contains a sintered metal filter installed in the horizontal orientation to prevent dust emissions;
the vessel comprises a first and a second opening, the first opening of the vessel is connected to an exhaust path exiting the vessel and the sintered metal filter is installed and sealed in the first opening in the vessel, the sintered metal filter is installed and sealed such that exhaust passes through the sintered metal filter before passing to the exhaust path and then being exhausted to atmosphere; and
the second opening is installed on the vessel directly opposite the first opening and is utilized to support the sintered metal filter in a horizontal manner within the vessel.
