MAZUT

Mazut is a heavy, low-quality fuel oil, which is typically used in generating plants and similar applications. It is a residue from the distillation of crude oil, known for its high viscosity and high sulfur content. Mazut comes in different grades, mainly determined by the levels of sulfur and viscosity, which affect its applications and handling.

Mazut 180 STS

Introduction

Mazut 180 STS (Straight Run Residue) is one of the lighter grades of Mazut fuel oil, with a lower viscosity and sulfur content compared to heavier grades. This makes it more suitable for certain industrial applications where these properties are required.

Properties of Mazut 180 STS

  1. Viscosity: Mazut 180 STS typically has a viscosity of about 180 centistokes at 50°C. This lower viscosity allows it to be pumped and handled more easily compared to heavier grades.
  2. Sulfur Content: This grade contains sulfur levels typically below 3.5%, which is lower than in heavier grades of Mazut.
  3. Density: Mazut 180 STS has a density of approximately 0.97 to 1.01 g/cm³, making it denser than light fuels but lighter than other grades of Mazut.
  4. Color and Odor: It is typically dark brown or black in color and has a strong odor characteristic of heavy fuel oils.

Benefits of Mazut 180 STS

  1. Ease of Handling: The lower viscosity of Mazut 180 STS makes it easier to pump, transport, and store, reducing operational costs and complexities.
  2. Versatile Applications: Suitable for a range of industrial applications where lighter fuel oil is required.
  3. Lower Emissions: With its lower sulfur content, Mazut 180 STS produces fewer sulfur dioxide emissions compared to heavier grades, making it slightly more environmentally friendly.
  4. Cost-Effective: It is more affordable than lighter distillates, providing a cost-effective fuel solution for industrial users.
