## What is the single-pass conversion?

Single-Pass Conversion = reactant input to reactor – reactant output from reactor. reactant input to reactor. ×100%

## How is recycling ratio calculated?

A recycle ratio is a key profitability measure of the oil and gas industry. The ratio is calculated by dividing the profit per barrel of oil by the cost of finding and developing that barrel of oil.

How do you calculate stream recycling?

When we study recycle systems, we are often asked to calculate the recycle ratio. Usually, this is found by dividing the mass flow of the recycle stream by the mass flow of the “fresh feed” entering the system.

### What is a fractional conversion?

Fractional conversion is defined as the number of moles of a compound that reacted divided by the amount of the moles that were fed.

### When and why is autocatalytic reactor used?

R4. 2 Recycle Reactors Recycle reactors are used when the reaction is autocatalytic, or when it is necessary to maintain nearly isothermal operation of the reactor or to promote a certain selectivity (see Section 5.6. 6). They are also used extensively in biochemical operations.

What is optimum recycle ratio?

in a recycle reactor, there must be a particular recycle ratio R, which. is optimum so as to minimize the reactor volume or space-time. ▪ The optimum recycle ratio is found by differentiating the. performance equation for recycle reactor, Eqn.7-1 with respect to R. ▪

#### What is the difference between recycle and bypass?

A recycle stream is one where a portion of the outlet of a process unit is combined with fresh feed and sent into the same unit again. A bypass stream is one where a portion of the inlet to a process unit is split from the feed and instead of entering the process is combined with the outlet from that process.

#### What is bypass stream?

DEFINITION. A bypass stream is one where a portion of the inlet to a process unit is split from the feed and instead of entering the process is combined with the outlet from that process.

What is sludge recycle ratio?

Typical recycle ratio values : Conventional activated sludge process = 0.25 – 0.50 ; Contact – Stabilization = 0.25 – 1.0 ; Extended aeration = 0.75 – 1.5 (used to control concentration of MLSS)
