Protection of Storage Tanks in Tank Farms

Protection of Storage Tanks in Tank Farms

for Refineries and Chemical Processing Plants with Flame Arresters, Valves and Tank Equipment

Protection of floating-roof storage tanks

Floating-roof storage tank with

  • floating-roof drainage system SE/K,
  • roof valve D/SR,
  • stem-actuated valve AL/DK with deflagration flame arresters EB,
  • rim vent P/EB.

Protection of fixed-roof storage tanks

Fixed-roof storage tank for flammable liquids with

  • UB/SF pressure relief and vacuum diaphragm valve,
  • LDA-F end-of-line liquid product detonation flame arrester,
  • DR/ES inert-gas blanketing with DV/ZT.

Protection of fixed-roof storage tanks

Fixed-roof storage tank for flammable liquids with

  • separate P/EB pressure relief pallet valve and SV/E vacuum relief pallet valve,
  • LDA-W or LDA-W-F liquid product detonation flame arrester in the filling and emptying line (as applicable),
  • SA/S floating suction unit,
  • DR/ES detonation-proof gas displacement connection.

Protection of fixed-roof storage tanks for non-flammable liquids

Fixed-roof storage tank for non-flammable liquids with

  • VD/SV pressure/vacuum valve and
  • ER/V emergency vent relief valve instead of pressure relief joint.

Protection of fixed-roof storage tanks for flammable liquids

Fixed-roof storage tank for flammable liquids with VD/SV-HRL pressure and vacuum relief valve, UB/SF pressure and vacuum relief diaphragm valve, connection to vapour manifold system with DR/ES detonation flame arrester and DV/ZT or DV/ZW pressure and vacuum relief pallet valve, LDA-W and LDA-WF liquid product detonation arrester in the filling line and emptying line, respectively.

Protection of underground storage tanks

Underground storage tank with

  • LDA-F safety valves in the filling line,
  • DR/ES detonation flame arrester in the drain line, and
  • DR/ES with VD/SV in the vent line.

Protection of aboveground storage tanks

Aboveground tank for flammable liquids with

  • pressure and vacuum safety relief valve PV/EBR,
  • liquid detonation flame arrester LDA in the filling line and an additional detonation flame arrester DA-G ensures that the tank is not emptied,
  • detonation proof foot valve for suction line EF/V,
  • detonation flame arrester DR/ES in vapour return pipeline.
