Oil Terminal Storage Tanks Equipment Pakistan
The oil terminal storage tanks and associated equipment manufactured in Pakistan are designed in compliance with international standards (e.g., API 650, API 620, ASME) for safe and efficient bulk storage of petroleum and petrochemical products. Pakistani manufacturers offer customised solutions for both vertical and horizontal storage tanks suitable for use at oil terminals, refineries, depots, and industrial facilities.
1. Pressure-Vacuum Relief Valves (PVRVs)
-
Maintain tank pressure within safe limits.
-
Prevent vapour losses due to minor pressure fluctuations.
2. Flame Arrestors
-
Prevent flames from entering the tank through vent openings.
-
Often installed in vent lines or near relief valves.
3. Floating Roofs
-
Internal Floating Roofs (IFRs) and External Floating Roofs (EFRs) minimise vapour space above the liquid.
-
Reduce emissions by limiting the surface area exposed to air.
4. Vapor Recovery Units (VRUs)
-
Capture and recycle vapours displaced during filling or breathing.
-
Commonly used at fuel terminals and petrochemical facilities.
5. Carbon Adsorbers
-
Use activated carbon to trap VOCs from vented gases.
-
Often paired with VRUs or used as a standalone system for low-throughput applications.
6. Thermal Oxidizers (Flares, Incinerators)
-
Burn off harmful vapours safely.
-
Common in large-scale or emergency vapour control.
7. Blanketing Systems (Nitrogen Blanketing)
-
Maintain an inert gas layer over the liquid to minimise oxygen contact and vapour emissions.
-
Also used to prevent explosions and contamination.
8. Emergency Relief Vents
-
Provide overpressure protection in abnormal conditions (e.g., fire exposure).
-
Help maintain structural integrity of the tank.
9. Desiccant or Condenser Systems
-
Remove moisture or condense vapours before venting.
-
Useful for reducing water vapour and capturing condensable hydrocarbons.
10. Tank Gauging and Monitoring Systems
-
Ensure safe fill levels and detect leaks or pressure deviations.
-
Integrated with control systems to trigger emission control responses.
