Description

Gases (Petroleum), Methane-Rich Off is a specialized hydrocarbon gas mixture derived from petroleum refining processes, characterized by a high concentration of methane. This product is a critical industrial feedstock and energy source, valued for its consistent composition and reliable performance in demanding applications. It is primarily utilized by the petrochemical, energy, and manufacturing sectors for chemical synthesis, fuel blending, and as a process gas.

Application

• Chemical Feedstock: Serves as a primary raw material for the synthesis of hydrogen, methanol, ammonia, and other valuable chemicals via steam reforming or partial oxidation.
• Industrial Fuel Gas: Used as a clean-burning fuel for industrial furnaces, kilns, boilers, and on-site power generation due to its high calorific value.
• Refinery Fuel & Process Gas: Employed within petroleum refineries to fuel process heaters and provide hydrogen for hydrotreating and hydrocracking units.
• Town Gas / Supplemental Gas: Can be blended into natural gas distribution networks to supplement supply or adjust heating value specifications.
• Metal Processing: Acts as a reducing atmosphere or fuel in heat treatment and metal fabrication processes.
• Glass & Ceramics Manufacturing: Provides a controlled, high-temperature flame essential for melting and forming processes.

Quality Control

Our Gases (Petroleum), Methane-Rich Off is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Composition is rigorously analyzed using gas chromatography (GC) to verify key parameters such as methane content, higher hydrocarbon levels, and inert gas concentrations. Certificates of Analysis (COA) detailing the specific composition and properties are provided with each shipment to support your quality assurance processes.

Storage

This product is a highly volatile, gaseous mixture under pressure. Preserve in a tightly closed container, protected from light. Cylinders or bulk storage vessels must be kept in a cool, well-ventilated area away from direct sunlight, heat sources, and ignition points. Storage temperature should not exceed 50°C (122°F). Ensure containers are properly secured and segregated from oxidizers.
