Definition: Molal Average Boiling Point (MABP) is defined as a measure of the boiling point of a mixture of compounds.
Purpose: It helps in characterizing petroleum fractions and other complex mixtures in chemical engineering processes.
The calculator uses the formula:
Where:
Explanation: The product of the characterization factor and specific gravity is raised to the third power to estimate the boiling point.
Details: Accurate boiling point estimation is crucial for refinery operations, distillation column design, and product quality control.
Tips: Enter the characterization factor (default 12.55) and specific gravity (default 0.82). All values must be > 0.
Q1: What is a typical range for characterization factor?
A: For petroleum fractions, it typically ranges from 10 to 13, with higher values indicating more paraffinic nature.
Q2: How is specific gravity measured?
A: It's measured as the ratio of the density of the substance to the density of water at standard conditions.
Q3: Why is the formula cubed?
A: The cubic relationship accounts for the non-linear relationship between molecular properties and boiling point.
Q4: Can this be used for pure compounds?
A: No, this formula is specifically designed for mixtures like petroleum fractions.
Q5: What are typical applications of MABP?
A: Used in refinery operations, crude oil characterization, and thermodynamic property estimation.
