Safety Nitrogen must be supplied in an approved Nitrogen gas cylinder and secured
to meet safety standards.
Do not use Nitrous Oxide cartridges as pressure sources for high-
temperature, high-pressure (HTHP) ltration. Under high temperature
and pressure, Nitrous Oxide can detonate in the presence of grease, oil,
or carbonaceous materials. Nitrous Oxide cartridges are to be used only
for Garrett Gas Train Carbonate Analysis.
Due to the high temperatures and pressures involved in this test, extreme
care must be exercised at all times. All safety precautions must be met,
especiallyinthecellbreakdownprocedureaftertheltrationprocedurehas
been completed.

1. Connect the heating well power cord to an appropriate power source.
Place a dial-type metal thermometer into the well in the heating jacket
and preheat to 10°F (6°C) above the desired test temperature. A pilot light
will come on when the heating jacket is at the desired temperature as
selected by the thermostat control knob.
2. Be sure all of the o-rings on the valve stems are in good working condition
(pliable with no nicks or cuts, etc.), and are not damaged during the
assemblyprocedures.Placeathinlmofsiliconegreaseonallo-rings.
Place an o-ring into one end of the test cell and place the screen on top of
itwiththeatsidefacingdown.Slowlypushoneofthecellcapsintothe
cell, making sure the arrow on the cap lines up with the arrow on the cell
body. Tighten the locking screws with the supplied allen wrench. Screw a
valve stem into the cell cap and tighten it completely.
Standard Buna N o-rings (#170-13) should be used only for tests up to
300°F (149°C). For tests over 300°F (149°C), use Viton®o-rings (#170-
13-3). After tests that come close to the maximum temperature, it will
probably be necessary to replace the o-rings.
If the cap locking screw seats are oval shaped and no longer
round, there is a possibility of stress failure and the cap should be
replaced.

5. Place the cell in the heating jacket. Rotate the cell in the heating jacket
so that the pin in the bottom of the heating well seats into the hole in the
bottom of the cell. This will anchor the cell inside the well and prevent the
cell from rotating as the valve stems are opened and closed. Transfer the
thermometer from the heating jacket to the thermometer well within the
cell.
6. Connect the pressuring assembly to the top valve stem and lock it in
place with the retaining pin. Place the back pressure receiver on the
bottom valve assembly and also lock it in place with the retaining pin.

7. Unscrew the T-screws (counter-clockwise) on the pressure manifold to
make sure both regulators are completely closed. Connect a nitrogen
cylinder (at least 1,500 PSI) to the center inlet on the pressure manifold.
Open the pressure release valve on the nitrogen bottle and note the bottle
pressure as registered on the middle manifold gauge.

8. Keeping the valve stems closed, adjust the two regulators on the nitrogen
manifold to the recommended back pressure for your test (refer to the
chart below). Open (loosen) the top valve stem ½ turn to pressurize the
sample.Maintainthispressureontheuiduntilthedesiredtemperature
is stabilized as indicated by the thermometer. The heating time of the
sample should never exceed one hour.
The upper and lower limits of the test pressure differential are determined
by the test temperature. As this temperature exceeds 212°F (100°C), the
back pressure must be increased in order to prevent vaporization of the
ltrate.The1,000PSIdifferentialpressuremustbemaintained,sothetop
pressure will have to be increased accordingly. The table below shows
the pressures recommended for various test temperatures.
