Overall Conversion Formula:
From: | To: |
Definition: Overall Conversion is defined as the ratio of difference of fresh feed and net product to the amount of fresh feed. It is defined for the overall process.
Purpose: It helps chemical engineers determine the efficiency of a recycle process by measuring how much of the fresh feed is converted to product.
The calculator uses the formula:
Where:
Explanation: The difference between fresh feed and net product is divided by the fresh feed amount to get the conversion ratio, then multiplied by 100 to get percentage.
Details: Calculating overall conversion helps optimize chemical processes, improve efficiency, and reduce waste in recycle systems.
Tips: Enter the amount of fresh feed and net product in moles. Both values must be ≥ 0, and fresh feed must be > 0.
Q1: What does 100% conversion mean?
A: 100% conversion means all fresh feed was converted to product with no remaining reactants.
Q2: Can conversion be negative?
A: No, conversion ranges from 0% to 100%. Negative values would indicate calculation errors.
Q3: How does this differ from single-pass conversion?
A: Overall conversion considers the entire process including recycle streams, while single-pass conversion looks at one pass through the reactor.
Q4: What units should I use?
A: While moles are shown here, any consistent mass or mole units can be used as long as both inputs use the same units.
Q5: What if my net product is greater than fresh feed?
A: This shouldn't happen in proper recycle systems. Check your measurements as this would give negative conversion.
