Reducing Operational Losses
Scientific management & technological upgrades — effectively curb hydrocarbon evaporation & leakage in oil storage
Upgrading Sealing Equipment
- High-efficiency sealing gaskets replace aged components → drastically reduces vapor leakage risk.
- Floating roof tanks — ensure tight rim seals to minimize evaporative losses from rim space.
- Fixed roof tanks — check & calibrate breather valve set pressure to prevent unnecessary venting due to pressure fluctuations.
- Source control — curbing vapor escape at the primary sealing interface improves overall containment.
Optimizing Operating Procedures
- Night/low-temperature scheduling — perform receiving & dispatching during cooler hours to reduce thermal breathing losses.
- Controlled flow rate — avoid violent agitation of liquid surface, minimizing vapor generation and mixing.
- Smooth operation — reduces frequency of internal pressure changes, maintaining stable tank atmosphere.
- Minimized ullage space — strategic scheduling lowers vapor release potential and product loss.
Strengthening Daily Maintenance
- Regular inspections — tank welds, flange connections, and seals checked for leaks; immediate corrosion remediation.
- Breather valve cleaning — prevent clogging to ensure proper pressure/vacuum relief, avoiding overpressure or tank damage.
- Equipment integrity — proactive maintenance prevents accidental emissions and unplanned losses.
- Leak detection & repair (LDAR) — systematic monitoring identifies hidden loss points before they escalate.
Applying Recovery Technology
- Vapor recovery units (VRU) — condensation, adsorption or membrane separation convert emitted vapors back into liquid product.
- Economic & environmental synergy — reduces direct product loss while lowering VOC emissions and carbon footprint.
- Automated recovery systems — continuous operation ensures maximum capture efficiency during loading/unloading.
- Sustainability compliance — technological upgrades align with strict environmental regulations and circular economy principles.
