Recycle Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Recycle Ratio = Volume Returned/Volume Discharged
R = V_R/V_D
This formula uses 3 Variables

Variables Used

Recycle Ratio - Recycle Ratio is defined as volume of feed, returned to the reactor entrance divided by the volume of the leaving streams.
Volume Returned - (Measured in Cubic Meter) - Volume Returned is the volume of the fluid returned to reactor entrance.
Volume Discharged - (Measured in Cubic Meter) - Volume Discharged is the volume leaving the system.

STEP 1: Convert Input(s) to Base Unit

Volume Returned: 40 Cubic Meter --> 40 Cubic Meter No Conversion Required
Volume Discharged: 133.33 Cubic Meter --> 133.33 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = V_R/V_D --> 40/133.33

Evaluating ... ...

R = 0.300007500187505

What is recycle in chemical engineering?

The essentials of the recycling method are that the mixture of both reacted and unreacted products reaches a separating system beyond the reactor where these products are separated from each other; then the unreacted part mixes with the fresh feed stock and the resulting mixture is passed into the reactor.

Why is chemical recycling important?

Chemical recycling could reduce the amount of plastic that ends up in landfills, thereby potentially reducing the release of harmful chemicals into the environment. Chemical recycling can also produce high-quality raw materials, thereby decreasing demand for fossil fuels and other natural resources.

How to Calculate Recycle Ratio?

Recycle Ratio calculator uses Recycle Ratio = Volume Returned/Volume Discharged to calculate the Recycle Ratio, The Recycle Ratio formula is defined as the volume of feed returned to the reactor entrance divided by the volume of the leaving streams. Recycle Ratio is denoted by R symbol.

How to calculate Recycle Ratio using this online calculator? To use this online calculator for Recycle Ratio, enter Volume Returned (V_R) & Volume Discharged (V_D) and hit the calculate button. Here is how the Recycle Ratio calculation can be explained with given input values -> 0.300008 = 40/133.33.

FAQ

What is Recycle Ratio?

The Recycle Ratio formula is defined as the volume of feed returned to the reactor entrance divided by the volume of the leaving streams and is represented as R = V_R/V_D or Recycle Ratio = Volume Returned/Volume Discharged. Volume Returned is the volume of the fluid returned to reactor entrance & Volume Discharged is the volume leaving the system.

How to calculate Recycle Ratio?

The Recycle Ratio formula is defined as the volume of feed returned to the reactor entrance divided by the volume of the leaving streams is calculated using Recycle Ratio = Volume Returned/Volume Discharged. To calculate Recycle Ratio, you need Volume Returned (V_R) & Volume Discharged (V_D). With our tool, you need to enter the respective value for Volume Returned & Volume Discharged and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Recycle Ratio?

In this formula, Recycle Ratio uses Volume Returned & Volume Discharged. We can use 3 other way(s) to calculate the same, which is/are as follows -
