Travis Richards sits down with Matt Parrott, the President of K2 Controls, Inc. K2 Controls boasts 30+ years of industry experience and serves production, pipeline, and distribution customers seeking accuracy and dependability in their measurement and odorization applications. In this episode, Travis and Matt talk about equations of state, the benefits of getting the correct representative samples, and maintaining accuracy in the equations of state. 

 

Topics Covered:

• The equation of state
• The hydrocarbon dew point
• The benefits of getting the correct representative sample
• How to maintain accuracy in the equation of state
• Gas sample conditioning systems

 

Equations of State (EOS) are mathematical correlations that link hydrocarbon properties to pressure, temperature, and fluid composition. People in the oil and gas industry understand that efficient engineering calculations require the properties of both gases and liquids. An EOS, therefore, is basically a fluid model utilized when determining the properties and the phase conditions of hydrocarbon mixtures. 

 

If you’re a total novice in this field, the second crucial term you must understand is the phase envelope. The phase envelope is the result calculated by the EOS that describes the liquid phase area, the two-phase area, and the gas phase area. During gas sampling, our primary focus area should be the gas regions. However, this often proves a difficult challenge due to the fact that numerous factors affect a specific hydrocarbon dew point.

 

A hydrocarbon dew point, on the other hand, is the pressure and temperature at which hydrocarbon components begin to condense out of the gaseous phase. During sampling, the HCDP is used as a quality parameter due to its sensitivity to specific gas stream components. 

 

So, why do we need to take the correct representative sample during oil and gas transactions? The correct representative sample of a hydrocarbon product is crucial when accounting for transactions and efficient product processing. Essentially, the producer, processor, and distributor need to verify the exact composition of the product from an economic and product treatment standpoint. Most experts assert that any investment made in a system designed to obtain an optimum sample will quickly be recouped by the savings made when correctly determining hydrocarbon composition. Furthermore, the potential for disputes in the business will be greatly reduced if the best sampling procedures are followed.
