The Solution: Control and Metering offered the Iso Flo 40 Bulk Bag Discharge system, utilizing an Isolation Chamber to guarantee containing any emissions to 0.01 PPM over an eight-hour period. A support base was custom designed to allow integration on a new mezzanine that was being constructed above the new charge tank. The TMA and Phthalic Anhydride ingredients flow fairly well, however the Adipic acid can set-up into a hard block. Control and Metering included a Bag Squeezer as an integral component of the Bag discharger to break up the set of the adipic acid bags.

The Iso Flo 40 discharger utilizes a Patented clamping arrangement that allows for clamping the bulk bag outlet spout to the down stream process thereby creating a closed discharge system. The system supplied to this customer incorporated pneumatic actuation of the clamping mechanism. The clamping arrangement is enclosed in our isolation chamber, which ensures that any ingredient that becomes airborne when the bag outlet is unclamped and the bag removed, is drawn completely out of the chamber. The chamber is maintained under a negative pressure via a single connection to a dust collection system. The combination of the Flo Super Clean and the isolation chamber completely eliminates emissions into the atmosphere. The Isolation Chamber utilizes a pair of openings with "letter slots" in a gum rubber membrane for operator access. The ingredients being discharged are supplied in either lined or unlined bags. The clamping arrangement supplied could be used for either type of bag.

The adipic acid has a tendency to form into a solid block that is impossible to get out of a bulk bag. A hydraulic bag squeezer is integrated as part of our support frame that allows the operator to squeeze the bag, thereby breaking up the ingredient in the bag, as it is being placed into the discharge hopper.
