Nitrogen Generator Membrane Area Sizing Formula calculator computes Membrane Surface Area in m^2 using the defined engineering formula and the input values provided. Membrane Surface Area is expressed in m^2. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Oxygen Removal Flow Rate = 0.05
  • Stage Cut = 0.2
  • Oxygen Permeance = 1.0E-6
  • Feed Pressure = 500000
  • Permeate Pressure = 101325
  • Oxygen Enrichment Factor = 1.5

Expected Result:

  • Membrane Surface Area = 0.066888233941598

Engineering Interpretation:

Under the given input conditions, the calculated result is: Membrane Surface Area = 0.066888233941598 m^2.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

membrane surface area = (oxygen removal flow rate * (1.0 - stage cut)) / (oxygen permeance * (feed pressure - permeate pressure) * oxygen enrichment factor)
