MINIVAP VPS or VPSH
MINIVAP VPS or MINIVAP VPSH
- the compact, portable and fully automatic instruments for the vapor pressure
determination of non-viscous liquids including, hydrocarbons and
solvents.
ROCKING PLATE
Vapor pressure measurements of crude oil cannot be performed
within a reasonable equilibrium time without stirring. Since a piston based
measuring cell cannot include a stirrer of any design, the instrument is placed
on the rocking plate to shake the sample inside the measuring cell. With this
method, the equilibrium time is between 10 and 20 minutes depending on the V/L
ratio.

FLOATING PISTON
CYLINDER (FPC)
Crude oil, especially life crude, is very sensitive
to loss of high volatiles and shall be introduced into the measuring cell under
pressure. The crude oil shall be contained in a pressurized floating piston
cylinder, with built-in manual stirring capabilities.
GRABNER INSTRUMENTS' new Floating Piston Cylinder
preserves the integrity of crude oil samples. This cylinder was specifically
designed for the new method for vapor pressure of crude oil . However, this
sample cylinder is also ideal for many other oil industry (ASTM VPCRx)
applications.
If you want to
measure the vapor pressure of crude oil according to the new ASTM method VPCRx
on-line, GRABNER INSTRUMENTS also has the perfect solution:
MINIVAP ON-LINE
MINIVAP ON-LINE is the first on-line application
of GRABNER INSTRUMENTS. It is based on the measuring principle of MINIVAP VPSH
in a nitrogen purged explosion-proof cabinet. Vapor pressure of gasoline, crude
oil, and LPG and Butane are determined on-line according to the new VPx, VPCRx
and LPG-Mini procedures. The vapor to liquid ratio temperature T(V/L=20) is
determined parallel to the vapor pressure of gasoline (ASTM D 5188). Three
different sample streams can be monitored alternately with automatic switching
between the streams. A sample conditioning system is installed below the
measuring unit and includes a fast sample loop with a flow indicator and a self
cleaning cyclon filter. A pressure regulator with minimum dead volume regulates
the high pressure of the product line to the pressure for the measuring
unit.
