The programOil Blendingcovers calculations in US customary and Metric units.

You can select from the drop-down list the way of calculations: in US customary units or in Metric units:
In calculations in **Metric units** you can select from the drop-down list which table to use for calculation of VCF (CTPL) by
selecting either Table 54A for"**Crude**", or
Table 54B for "**Product**", or Table 54D for "**Lube**":
In calculations in **US customary units** you can select from the drop-down list which table to use for calculation of VCF (CTPL)
by selecting either Table 6A for "**Crude**", or
Table 6B for "**Product**", or Table 6D for "**Lube**":

In addition to the quality parameters of the blend you can calculate the
price of the blend, if you fill in the price of each componenet either in US dollars per US
barrel or per Metric ton in air as shown on the above pictures.

In both options of calculations (**"Metric units"** or **"US customary
units"**), you can calculate the following quality parameters of the oil blend.
Some parameters may have several different methods of calculations and you can select the method to be used
from the drop-down list:
You can select an option of taking into account olefin and aromatics content while calcu-

lating Octane numbers (RON or MON):
Youcan also calculate the density of the blend of the heavier component with a lighter diluent.
The big difference in densities of the heavier component and of
the diluent usually result in shrinkage which is taken into account in calculations. Such calculations allow up to 6 iterations
of calculations:
For your convenience in **Oil Blending** you can use a built-in interpolation
calculator of volumes allowing to take into account simultaneously product level (ullage or innage) and the trim
or list correction:
As you can see, this program has a lot of useful features designed to automate and facili-

tates the calculation of quality
parameters of the blend and its price.

We only showed some of useful capabilities available in our oil blending program.

There is also a converter of temperatures and viscosities, like the calculation of the visco-

sity at
the different temperature knowing viscosities at two different temperatures or
knowing only one viscosity at a certain temperature by means of a beta-factor either for a light or a dark product.
