Description

4 Fuel Oil CAS NO 68476-31-3 is a complex hydrocarbon mixture, primarily composed of residual fuel oils, designed for high-energy industrial applications. This product is critical for operations requiring a reliable and cost-effective source of thermal energy or power generation. It is essential for industries such as marine shipping, large-scale heating, and heavy manufacturing where consistent fuel performance is paramount.

Application

• Marine Fuel (Bunker Fuel): Primary fuel for large ocean-going vessels and cargo ships.
• Industrial Boilers and Furnaces: Used for steam generation, process heating, and thermal fluid systems in manufacturing plants.
• Power Generation: Fuel for stationary engines and turbines in dedicated power plants or for on-site industrial co-generation.
• Large-Scale Heating: Provides heat for commercial buildings, district heating systems, and institutional facilities.
• Cement and Lime Kilns: Serves as a high-temperature fuel source in heavy industrial processing.
• Blending Component: Used in the formulation of various fuel oil grades to meet specific viscosity and sulfur specifications.

Quality Control

Our 4 Fuel Oil is produced and tested to meet stringent industry specifications for viscosity, sulfur content, flash point, and water/sediment levels. Quality is assured through a rigorous analytical protocol, including methods such as ASTM D4294 for sulfur and ASTM D445 for kinematic viscosity. A Certificate of Analysis (COA) detailing key parameters is provided with each shipment to ensure compliance and performance consistency for our global clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, sparks, and open flames. Tanks and containers should be kept sealed to prevent water contamination and minimize evaporation. Follow all local and international regulations for the storage of combustible liquids.
