Abstract

Spill pans for industrial-use chemical processing systems often experience ultimate leakage at the drain/pan interface. A monolithically constructed spill-containment pan achieves increased durability and dependability against leakage by admitting a sump pump through a controlled entry as described in the following. As seen in the end view drawing (Fig. 1) the pan 1 is constructed on a structural concrete slab 2. The pan 1 is a one-piece item supporting equipment module 3, which rests on equipment pad 4. The process chemicals used are pumped to equipment module 3 through an entry pipe 5. Any chemicals that spill into the pan are carried by an inclined pan slope 6 until they settle in a sump pit 7 where a drain sump intake 8 removes chemicals through sump drain pipe 9.

Monolithic Fiberglas/Grout Spill Containment Pan Utilizing Sump Drain Through Controlled Entry

Spill pans for industrial-use chemical processing systems often experience ultimate leakage at the drain/pan interface. A monolithically constructed spill- containment pan achieves increased durability and dependability against leakage by admitting a sump pump through a controlled entry as described in the following. As seen in the end view drawing (Fig. 1) the pan 1 is constructed on a structural concrete slab 2. The pan 1 is a one-piece item supporting equipment module 3, which rests on equipment pad 4. The process chemicals used are pumped to equipment module 3 through an entry pipe 5. Any chemicals that spill into the pan are carried by an inclined pan slope 6 until they settle in a sump pit 7 where a drain sump intake 8 removes chemicals through sump drain pipe 9. The sump drain pipe 9 exits pan 1 through a controlled entry opening 10. A raised section 11 prevents chemicals from entering the drain pipe except through intake
8. The sump drain pipe 9 is sealed against leaks by a top cover seal 12. The drain pattern is sloped from left to right, as seen by the arrow in the drawing, toward sump pit 7 where chemicals are pumped out. The pan is also sloped from front to back (not seen in drawing). A fiber fireproofing material 13 is designed such that if a fire melted the PVC piping 9 the fiber material 13 also melts to close the void. A poly sulfide rubber pourable grad...
