Glycol Dehydration Still Column Diameter Formula

d=9.1qgd=9.1\sqrt{q_g}

Glycol Dehydration Still Column Diameter calculates still column diameter for well performance workflows in production engineering.

Calculate

How engineers use this formula

Use this formula when the listed inputs (q_glycol) are known and the assumptions behind the cited well performance relationship match the engineering case being checked.

Assumptions

  • Input values are representative for the well, reservoir, fluid, or equipment case being evaluated.
  • The declared units match the field-unit constants used in the formula.
  • The cited formula applies to the selected petroleum engineering workflow.

Limitations

  • The calculation does not replace a full engineering model or operating procedure.
  • Accuracy depends on the source correlation, assumptions, input quality, and unit consistency.

Common mistakes

  • Mixing unit systems without converting the inputs.
  • Using default example values as field recommendations.
  • Applying the formula outside the source assumptions.

Default example

Using the default inputs, d_still equals 18.2 in.
