Can we calculate the Total Calculated Volume (TCV) as a target quantity for our crude oil MQCI conversion group?

The definition of the Total Calculated Volume (TCV) is:

TCV equals gross standard volume (GSV) plus free water (FW) – API MPMS Chapter 12.1.1.

TCV = GSV + FW ( in appropriate UoM, e.g. FW and GSV in barrels)

You utilize a QuantityWare BCP crude oil conversion group, that is configured to calculate gross and net quantity values (see separate FAQ) . You want  the TCV quantity being calculated as additional quantity value.

Example:

The free water (FW) volume is given as 10 barrels at 60 °F.

For our ethanol DCF conversion group, we need to calculate the dehydrated ethanol volume. Is this possible?

For your MQCI DCF ethanol conversion group, you wish to enter two additional input parameters for the quantity conversions

  1. the weight % fraction of pure ethanol in your ethanol product
  2. the absolute density of pure ethanol – e.g. 0.78924 g/ml (= 789.24 kg/m³) @ 20 °C

such that the system calculates, in addition to the existing UoM in your UoM group, the liter @ 20 °C value of pure ethanol. That calculation shall be based on the following formula:

Volume @ 20 °C (pure ethanol) [L]

 = weight of product [kg] × weight fraction (pure ethanol) ÷ absolute density (pure ethanol) [kg/L]

Depending on your business process design and configuration (e.g.

How can we calculate the GSV from TCV (Total Calculated Volume) using QuantityWare BCP?

The definition of the Total Calculated Volume (TCV) is:

TCV equals gross standard volume (GSV) plus free water (FW) – API MPMS Chapter 12.1.1.

Thus, GSV = TCV – FW ( in appropriate UoM, e.g. FW and GSV in barrels)

You utilize a QuantityWare BCP crude oil conversion group, that is configured to calculate gross and net quantity values (see separate FAQ) . You want to enter a TCV value as transaction quantity and the FW value for the calculations.

Example:

The free water (FW) volume is given as 120 barrels at 60 °F.
