Ternary Diagrams in Crude Oil Classification

The video tutorial demonstrates the use of ternary diagrams for classifying crude oils. It focuses on type 4 aromatic-naphthenic crudes, highlighting their boundaries based on aromatic, naphthene, and paraffin content. The tutorial also covers group 5 aromatic-intermediate crudes and type 6 aromatic-asphaltic crudes, explaining how to identify these types using boundary lines on the ternary diagram.

What is the primary focus of using ternary diagrams in this tutorial?

• To classify different types of metals

• To explain the process of distillation

• To demonstrate the use of color theory

• To classify crude oils based on their composition

Which component must be greater than 50% in type 4 aromatic-naphthenic crudes?

• Naphthenes

• Sulfur

• Aromatics

• Paraffins

What is the significance of the horizontal line in the ternary diagram?

• It indicates the start of the diagram

• It separates type 4 and type 5 crudes

• It marks the boundary for paraffins

• It designates the boundary for aromatics

In the ternary diagram, where are naphthenes greater than 25%?

• Above the line

• Below the line

• To the left of the line

• To the right of the line

What is the combined condition for the orange triangle in the ternary diagram?

• Paraffins < 10% and Aromatics < 50%

• Aromatics > 50% and Paraffins > 10%

• Naphthenes > 25% and Paraffins < 10%

• Aromatics > 50% and Naphthenes > 25%

What is the third boundary line for type 4 crudes?

• Paraffins less than 10%

• Aromatics less than 50%

• Sulfur less than 5%

• Naphthenes less than 25%

Which region is identified by paraffins greater than 10% and aromatics greater than 50%?

• Type 6 aromatic-asphaltic crudes

• Type 4 aromatic-naphthenic crudes

• Type 3 paraffinic crudes

• Type 5 aromatic-intermediate crudes

What are the boundaries for type 6 aromatic-asphaltic crudes?

• Naphthenes less than 25% and Paraffins less than 10%

• Paraffins greater than 10% and Naphthenes less than 25%

• Aromatics greater than 50% and Paraffins greater than 10%

• Naphthenes greater than 25% and Aromatics less than 50%

Which type of crude is found in the gray shaded region of the ternary diagram?
