A storage container for storing quantities of acids and other volatile liquids is described having a recirculation system that can include a recirculation pump and a recirculation line that goes from a bottom end of the container toward a top end of the container, where the recirculation line has a plurality of pressure relief valves spaced along its length. The storage container may also include a leak detection system and a high level warning system.

A holding container includes a plurality of pre-formed, releasably interlocking, load-bearing panels configured to form an at least partially curved, load-bearing wall extending around the perimeter of at least one storage area capable of containing at least 100,000 gallons of liquids, solids or a combination thereof. At least one among the width and length of each panel is less than 102 inches in a non-load-bearing state.

A piled grain surface management robot comprises an auger-based drive system, a memory, and a processor coupled with the memory. The processor is configured to control movement of the robot via the auger-based drive system. The processor is also configured to direct a traversal of a surface of piled grain in a bulk store, wherein a crust layer of the surface is broken up by auger rotation of the auger-based drive system during the traversal.

A bulk storage bin is provided for grain and particulate material and includes a hopper bottom formed by a plurality of trapezoidal panels, each having upper and lower edges and opposite side edges. Flanges extend outwardly along each edge of each panel to provide a bolted flanged joint for adjacent panels. Plate assemblies extend along the upper edge of each panel to form a continuous 360 compression ring when the panels are assembled. Each flange has a portion extending behind the plate assemblies, with interior bolt holes. An access hole is provided at each end of each plate assembly for access to the interior bolt holes.
