Necessary Inhibitor Concentration Required in Liquid Phase to Reduce Hydrate Point Formula

X=100dMdM+2335X=\frac{100dM}{dM+2335}

Necessary Inhibitor Concentration Required in Liquid Phase to Reduce Hydrate Point calculates required inhibitor concentration in liquid phase for gas properties workflows in phase behavior and thermodynamics.

Calculate

How engineers use this formula

Use this formula when the listed inputs (d, M) are known and the assumptions behind the cited gas properties 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, X equals 12.052731 wt%.
