Liquefied Petroleum Gas (LPG)

Propane & Butane Mixture | Industrial & Fuel Grade | Persian Gulf Star Refinery | UN 1075 | Supplier: MizanPetroGas

Product Introduction

Liquefied Petroleum Gas (LPG) is one of the most versatile and strategic hydrocarbon energy sources in global trade, primarily composed of a mixture of propane ($C_3H_8$) and butane ($C_4H_{10}$). Under ambient conditions (standard atmospheric temperature and pressure), LPG exists in a gaseous state; however, under moderate pressure (approximately 8–10 bar) or refrigeration, it readily condenses into a liquid — a physical property that makes storage, long-distance transportation, and distribution highly efficient and economical. The liquid-to-gas expansion ratio is approximately 1:250, meaning one liter of liquid LPG expands into roughly 250 liters of gaseous fuel when depressurized.

The LPG supplied by MizanPetroGas Company is sourced directly from the Persian Gulf Star Gas Condensate Refinery — the largest gas condensate refining facility in the world. Characterized by an ultra-low sulfur content of under 50 ppm, complete absence of corrosive compounds, and zero heavy olefin contamination, this product serves as a clean-burning, high-efficiency, environmentally sound energy source. Compared to heavy liquid fuels such as heavy fuel oil and diesel, LPG significantly reduces $CO_2$, $NO_x$, and particulate matter emissions. The propane-to-butane blending ratio is fully customizable based on destination climate, seasonal temperature shifts, and operational requirements — ranging from winter grades with high propane ratios (60:40) for cold climates to summer grades with predominant butane content (30:70) for hot regions.

Leveraging an integrated supply chain, specialized pressurized gas logistics, and established international partners, MizanPetroGas supplies commercial volumes of LPG on FOB, CIF, and CFR terms from primary export terminals in southern Iran to regional and global markets.

Safety Considerations and Handling

• Ignition Sources: Maintain a minimum safety distance of 15 meters from open flames, sparks, smoking materials, and non-explosion-proof electrical apparatus. All processing equipment and vehicles must be properly grounded and bonded. Use non-sparking tools exclusively in handling areas.
• Ventilation: Storage must be restricted to open-air areas or spaces equipped with explosion-proof mechanical ventilation providing at least 12 air changes per hour. Install LPG gas detectors at ground level (within 30 cm of the floor) linked to automatic alarms and emergency isolation valves.
• Personal Protective Equipment (PPE): Wear cryogenic insulated gloves when handling liquid transfers to prevent severe freeze burns. Safety goggles, full face shields, flame-retardant anti-static clothing, and static-dissipative safety boots are mandatory.
• Cryogenic Burn Hazard: Direct skin or eye contact with rapidly expanding liquid LPG causes instant cryogenic frostbite (-42 °C to -0.5 °C). In case of contact: flush immediately with tepid water and seek emergency medical treatment — never rub the affected area.
• Emergency Leak Response: Unignited leak: eliminate all ignition sources immediately, isolate and evacuate the area, and disperse gas clouds using water fog/spray (never use solid water streams). Ignited leak: do not extinguish the flame unless the gas feed can be isolated immediately (to avoid explosive vapor cloud accumulation); cool adjacent storage vessels with continuous water spray.
• First Aid: Inhalation: move victim to fresh air immediately and administer artificial respiration or supplemental oxygen if needed. Eye Contact: flush thoroughly with water for $\geq 15$ minutes and obtain immediate medical examination. Ingestion: not considered a normal route of exposure; never induce vomiting.
• Chemical Incompatibilities: Keep strictly segregated from strong oxidizing agents (chlorine, fluorine, peroxides, nitric acid, nitrates) and extreme heat sources to prevent violent or explosive reactions.
• Periodic Tank Inspection: Pressure storage vessels must undergo annual integrity inspections covering shell corrosion, valve operability, pressure relief setting, and structural coatings, accompanied by hydrostatic testing in compliance with international pressure vessel codes.

Price Inquiries and Order Execution

LPG commercial pricing fluctuates based on international propane and butane benchmark rates (Saudi CP, Mont Belvieu, ARGUS FEI), VLGC ocean freight rates, destination port tariffs, and agreed contract volumes. The commercial desk at MizanPetroGas provides transparent pricing structures, customized logistics planning across multimodal networks, and coordinated third-party inspection arrangements (SGS / Bureau Veritas) tailored to your required delivery terms (FOB / CIF / CFR / DAP).
