NEW METHOD
MINIVAP LPG is a stand-alone unit for fully automatic vapor pressure
determination of liquified petroleum products. The measuring principle utilizes the
built-in piston for automatic sample introduction and sample chamber volume
adjustment. It offers safe and easy operation and reduces pollution of the
environment. A printer with a serial interface can be connected directly for
immediate printout of the measured data. In the field, the tester is powered from a
vehicle battery and the measured data are stored in the internal memory for later
documentation.
principle of operation
SIGNIFICANCE AND USE
(from ASTM D 1267)
Information on the vapor pressures of liquefied petroleum gas products under
temperature conditions from 37.8 to 70°C (100 to 158°F) is pertinent for the
selection of properly designed storage vessels, shipping containers, and
customer utilization equipment to ensure safe handling of these products.
Determination of the vapor pressure of liquefied petroleum gas is important for
safety reasons to ensure that the maximum operating design pressures of
storage, handling, and fuel systems will not be exceeded under normal operating
temperature conditions. For liquified petroleum gases, vapor pressure is an
indirect measure of the most extreme low temperature conditions under which
initial vaporization can be expected to occur. It can be considered a semiquantitative measure of the amount of the most volatile material present in the
product.
EQUIVALENT TO ASTM D 1267
The test results are equivalent to ASTM D 1267 but with a significant smaller
sample volume and a striking simplified and reliable measuring procedure. The
procedure of filling to 3.3 or 3 mL and expansion to 5 mL with a final vapor/liquidratio of 1:2 or 2:3 is consistent to the purging and filling procedure of ASTM D
1267 (33.3% or 20% upper chamber).
PROTECT THE ENVIRONMENT
Only 10 mL of LPG are disposed off during the filling and measuring procedure.

MINIVOL LVR is a tester for the automatic determination of the Vapor/LiquidRatio temperature. Nonviscous liquids like gasoline, solvents and other highly
volatile compounds can be tested with high precision in a range of 20 to 80°C (68
to 176°F). The nominal pressure for the test can be adjusted between 50 kPa and
200 kPa.
FULLY AUTOMATIC
The instrument performs fully automatically with a sample volume of 5 mL
only.The syringe is filled with the sample and inserted into the Luer-lock on the
right hand side of the instrument.
principle of operation
SIGNIFICANCE AND USE(ASTMD 5188)
The tendency of a fuel to vaporize in automotive engine fuel systems is indicated
by the Vapor/Liquid-Ratio of the fuel. Automotive fuel specifications generally
include T(V/L=20) limits to ensure products of suitable volatility performance.
Studies of vapor lock behavior are best performed by measuring multiple point
measurements at different nominal pressures.
TEST METHOD
The measuring chamber with a volume of 15 mL is evacuated and heated above
the expected temperature. After flushing the chamber with sample and further
evacuation, the exact amount of liquid for the first point is injected and the
temperature is decreased until the nominal pressure (e.g. 101.3 kPa) is observed.
The results are calculated according to
V/L=(V - v)/v
V... Volume of the test chamber
v... injected sample volume
MULTIPLE POINT MEASUREMENT
For multiple point evaluation, the test is started with V/L=100 and the next steps
of V/L=80 down to V/L=4 are measured consecutively by adding the respective
amount of sample.
MAGNETIC STIRRER
A magnetic stirrer inside the measuring chamber serves for fast equilibrium and

NEW DESIGN
MINIVAP VOC is an instrument for the automatic determination of the vapor
pressure of pure and contaminated organic compounds and low vapor pressures
of various substances, even solids, at test temperatures of 10 to 100°C (50 to
212°F).The generally low vapor pressures can be measured up to 100 kPa (14
psi, 760 mm Hg). The minimum detectable vapor pressure is 0.5 kPa (0.05 psi).
Dissolved and entrained fixed gases are removed from the sample by evacuation
at a low temperature to minimize composition changes.
principle of operation
APPLICATIONS
(From ASTM D 2879-86)The vapor pressure of a substance reflects a property of
the sample as received, including most volatile components, but excluding
dissolved fixed gases such as air. Vapor pressure is a thermodynamic property
which is dependent only upon composition and temperature for stable systems.
Government regulations require vapor pressure values forpractically all liquids
which are stored or shipped because of safety and environmental protection
reasons.
ASTM D 2879 (ISOTENISCOPE)
An isoteniscope is the standard instrument for measuring low vapor pressures.
This method is very tedious to use and needs highly skilled and experienced
personnel especially for the outgassing procedure. The measurement is time
consuming and not very reliable. In MINIVAP VOC the outgassing procedure is
performed at a low temperature and it can be assumed with high confidence that
the composition change of the substance is minimized.
AUTOMATIC PROCEDURE
The sample is filled into the sample cup. The temperature program together with
the outgassing procedure is performed fully automatically.
MAGNETIC STIRRER
Stirring is vital for the outgassing procedure and is accomplished during the whole
measuring procedure.

CERTIFIED TECHNOLOGY
The measuring principle is based on the patented triple expansion method of
Grabner Instruments´ worldwide approved and accepted laboratory vapor
pressure tester for gasoline and crude oil: MINIVAP VPS. The US-EPA declared
MINIVAP as the official reference instrument for the USA in 1993.
ONE INSTRUMENT FOR ALL RELEVANT ASTM STANDARDS
With MINIVAP ON-LINE, the vapor pressure of gasoline (D 6378 / D 5191), crude
oil (D 6377 / D 323), liquid petroleum gas (D 1267) and the vapor-liquid ratio
temperature of gasoline (D 5188) can be determined.
With possible connection of up to 3 different sample streams, all of these
measurements can be performed with one single instrument.
ON-LINE CONVENIENCE LABORATORY PRECISION
The advanced MINIVAP method considerably improves the quality of your
measurement and leads to a much better accuracy. This offers the possibility to
blend as close as 0.3 kPa (0.05 psi) to the official limits, saving refineries
thousand of dollars each year.
REMOTE CONTROLLED
The data is transferred safely via Fiber-Optics to the central controller outside the
explosion sensitive area. The controller continuously displays the actual vapor
pressure and can forward the results to a LIM-system via the analog outputs.
principle of operation
AUTOMATIC CALIBRATION
A fully automatic calibration of the measuring unit is performed with a vapor
pressure measurement of neo-hexane, or other standard liquids. It can either be
started manually, or automatically in programmable intervals.

MINIVAP ON-LINE consists of four main parts:
1. Sample conditioning system:
The sample conditioning system is mounted on a stainless steel plate consisting
of a manual input and output valve for the connection to the sample stream. The
liquid flows in the sample loop with a minimum flow rate of 2 L/min and a
maximum pressure of up to 7000 kPa (1000 psi).
The sample passes through a flow-indicator to a self-cleaning bypass-filter with a
desirable, small secondary volume. The sample pressure after the filter is
regulated with a pressure regulator having two pressure gauges for inlet and
outlet. Then, the sample is fed via the sample outlet valve directly to the sample
input of the enclosure for measurement.
An atmospheric drain outlet for the sample waste disposal and a second drain
outlet with less than 100 kPa (14 psi) for the pressure relieve valve of the
pressure regulator is mounted on the plate. The standard calibration liquid is
contained in a 250 mL bottle secured in a stainless steel box. Up to three sample
streams can be connected and monitored consecutively.
2. Purging system:
The purging system is mounted beside the measuring system. It is a
pressurization or purging system which operates on a supply of compressed inert
gas.
It is designed to regulate and monitor the pressure of a sealed (protected)
enclosure, in order to prevent ignitable dust accumulation or remove and prevent
flammable vapor accumulation within the enclosure. In Class 1 Areas, the system
is designed to accomplish programmable air exchanges and maintain a "safe"
pressure on the enclosure.
In addition, the system includes an electrical power control unit (EPCU) that
monitors system operation and controls enclosure power. All start-up
requirements must be satisfied before the EPCU will energize the power to the
enclosure. These processes reduces the Hazardous (Classified) Area Rating
within the enclosure, in accordance with the CENELEC 1/IIB, EN 50016
(European system) or the NEMA Class 1, BCD, Div2, Type "X", T6 (US system).
3. Measuring system:
http://www.grabner-instruments.com/m_online.htm
6/25/01
MINIVAP ON-LINE - Grabner Instruments - innovative automatic quality control instrum.. Page 3 of 3
The heart of the equipment is the measuring system with the measuring unit and
the controller.
The measuring unit consists of the measuring cell which is heated and cooled by
peltier elements, the piston with the pressure transducer and the piston drive. It
rests on a hinge of a heavy aluminum plate and is connected to the system with 4
unmistakable connectors. The sample inlet and outlet are linked via two
Swagelok quick connectors to the magnetic valves. These valves are connected
to the sample conditioning system and to the calibration fluid container and
control the sample flow trough the cell.
The maintenance is very easy since the measuring units can be exchanged in
less than one minute. The measuring units are interchangeable since the values
for pressure and temperature are stored in a FLASH-RAM installed in the
measuring unit. As soon as the microprocessor-controller is connected, the
values are transferred. The controller with its large display is mounted on two
hinges and can be turned out from the enclosure for easy access. The complete
measuring system is housed in a stainless steel enclosure which is continuously
purged with nitrogen.
4. Central Controller
The central controller is placed in a non-hazardous area and is connected via a
glass fiber optic cable to the measuring system for remote control. Furthermore,
the measured values are displayed and prepared for further data transfer. The
unit is housed in a 19"/4HU (450x185x260 mm) rack with a built-in power supply
and up to 6 controller inserts. For each measuring channel one insert with its own
display is installed. All inserts are serially connected to a fiber optic modem, which
is installed in the power supply. A complete remote control of the measuring
system is possible.
Two standard RS 232 interfaces for direct connection of a printer and for remote
control are incorporated in each controller.
Additionally, each controller unit accommodates independent inputs and outputs:
1 analog output 0 to 20 mA
Analog signal for the measured vapor pressure or vapor-liquid-ratio temperature
(calibrated by the user)
4 digital inputs freely programmable for remote control
6 digital outputs (2 A relays) freely programmable for alarm and control.
Alarms can be programmed in the central controllers directly. The analog output
may be used for simple process regulators.

FLOATING PISTON CYLINDER (FPC250)
The new Floating Piston Cylinder (FPC250) was designed in cooperation with
Norwegian offshore personnel specifically for ASTM D 6377. A mechanical stirrer
is included to ensure uniform samples. No valve stems or handles protrude from
the cylinder, reducing hazards.
ROCKING PLATE
MINIVAP is placed on the Rocking Plate to shake the sample inside the
measuring cell, reducing the equilibrium time significantly.
STOP WASTING YOUR TIME WITH SAMPLING PROCEDURE
OF ASTM D 323
The pressurized crude oil from the FPC or pipeline is directly transferred into the
measuring chamber and the vapor pressure is measured against vacuum by a
single expansion.
The derived precision is significantly better than the classical method of D 323.
Cooling and air saturation are NOT required!
