Many times the designer is given the mole fraction of each component in the feed stream but is not given the mole flow rate for the stream. It may be necessary to estimate the total number of moles in the feed stream (F) from an expected stock tank oil flow rate. As a first approximation, [...]]]></description>

The liquid flow rate in moles per day for a given inlet stream can be determined from Equation 3-17. In our example, for an inlet stream rate of 10,000 moles per day, the liquid flow rate is:


The liquid flow rate in barrels per day can be derived from:


where Q1 = liquid flow rate, bpd

Remembering that the weight of each component is the number of moles of that component times its molecular weight (pounds = MW X moles), the specific gravity of the liquid is given by:



Column 5 lists a specific gravity for each component in the liquid phase at standard conditions except as noted. It would be more [...]]]></description>

Derivation of Equation 3-13

		<description><![CDATA[In the absence of any laboratory data, correlations exist that relate viscosity  and temperature, given the oil gravity. The following equation  relating viscosity, gravity, and temperature was developed by Beggs and  Robinson after observing 460 oil systems:


The data set from which this relationship was obtained included a range of between 16° and 58° API and [...]]]></description>

		<description><![CDATA[This property of a fluid indicates its resistance to flow. It is a dynamic property, in that it can be measured only when the fluid is in motion. Viscosity, therefore, is simply the ratio at any shear rate of the shear stress to the shear rate. There are two expressions of viscosity, absolute (or dynamic) [...]]]></description>
