Load Cell Accessory Kit:
#170-00-4S-LC: Load Cell Assembly; Qty: 4
#170-00-4S-013: 4-Port USB Hub

Nitrogen must be supplied in an approved Nitrogen Gas Cylinder and secured to meet safety standards.

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, especially in the cell breakdown procedure after the filtration procedure has been completed.

Cell Corrosion
Test fluids under high tempreature and pressure can corrode the cell body and caps. Carefully inspect the cell body and calls for corrosion before and after each test.

Some materials are more susceptible to corrosion than other. Also, some fluids and additives are more corrosive than others. OFITE offers a variety ofcell materials for different levels of corrosion resistance and cost.

Setup

1. Remove the instrument from the crate and place it on a flat, stable surface.
2. Turn off the Nitrogen valve (horizontal). Turn off both Main Power switches and all four Heat switches. Make sure all regulators are backed off completely. Turn them completely counterclockwise.
3. Connect a Nitrogen source to the back of the unit. The inlet connector is ¼” NPT.
4. On the back of the unit is a power inlet configured for 115 VAC or 230 VAC. Plug the supplied power cord into an appropriate power source.

• #170-00-4S: 115 VAC, 50/60 Hz
• #170-00-4S-230: 230 VAC, 50/60 Hz

Operation

Although all four test cells share a single Nitrogen source, they each have two regulators for adjusting drive pressure and back pressure. Each cell also has a separate temperature controller.

There are two main power switches on the front of the instrument. The switch on the left controls power to the two cells on the left. The switch on the right controls power to the two cells on the right.

The valve on the front controls the flow of Nitrogen pressure to the regulators. When the valve is horizontal, the pressure is turned on. When it is vertical, the pressure is turned off.

Note

Tip

1. Before starting a test, make sure the Nitrogen valve is off (vertical). Turn off both Main Power switches and all four Heat switches. Make sure all regulators are backed off completely. Turn them completely counterclockwise.
2. Turn the Main Power switches on.
3. Press the up and down arrows on the temperature controller to set the desired test temperature.
4. Turn the Heat switch on. Each cell has a separate Heat switch. The light next to the cell will turn on when the heaters are engaged.
5. Be sure all of the o-rings are in good working condition (pliable with no nicks or cuts, etc.), and are not damaged during the assembly procedures. Place a thin film of silicone grease on all o-rings.
   Nitril-NBR (Buna N) o-rings (#170-13) are recommended for tests up to 250°F (121°C). For tests up to 400°F (204°C), Fluorocarbon/FKM (Viton®) o-rings (#170-13-3) are recommended. For tests up to 500°F (260°C), Perfluorocarbon (FFKM) o-rings are recommended. Also, for tests with water-based fluids containing no hydrocarbons, Ethylene propylene (EPM/EPDM) o-rings may be used up to 400°F (204°C).
6. Screw a valve stem into the test cell on the side opposite the cell cap. Tighten the valve stem completely.
7. Prepare the sample according to API specifications.
8. Carefully pour the sample into the cell. Do not fill the cell closer than 0.5″ 13 mm) from the o-ring groove to allow for heat expansion of the fluid. Be careful not to spill fluid in the o-ring groove.
9. Place an o-ring in the o-ring groove inside the cell. Place another o-ring in the recess in the cell cap.
10. Place a circle of filter paper on top of the cell o-ring and slowly push the cell cap into the test cell. Make sure the arrow on the cell cap lines up with the arrow on the cell body. Tighten the cap locking screws.
    Important
    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.
11. Screw another valve stem into the cell cap and tighten it completely. The cell is now completely sealed.
    
12. Place the cell in the heating jacket with the outlet or filter side of the cell pointed down. 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.
13. Transfer the thermocouple from the heating jacket to the thermometer well within the cell.
14. Connect the manifold block to the top valve stem and lock it in place with the retainer pin. Place the back pressure receiver on the bottom valve stem and lock it in place with the other retainer pin. Make sure both relief valves and both valve stems are closed.
    
15. Turn the Nitrogen valve on.
16. Set the top and bottom regulators to the recommended back pressure for your test.
    This instrument is equipped with check valves between the regulators and the pressure outlet to protect the regulators from backflow. If you increase the regulator pressure and then decrease it, there may be extra pressure remaining in the lines.
    

    Recommended Minimum Back Pressure
    Test Temperature	Vapor Pressure	Minimum Back Pressure
    °F	°C	psi	kPa	psi	kPa
    200-299	95-149	12.1-67	84-462	100	700
    300-374	150-189	67-184	462-1269	200	1400
    375-399	190-199	184-247	1269-1704	275	1900
    400-424	200-219	247-326	1704-2245	350	2500
    425-450	220-230	326-422	2245-2912	450	3100

17. Open the top valve stem by turning it one quarter turn. This will add pressure to the test cell. Maintain this pressure until the sample temperature stabilizes. The heating time of the sample should never exceed one hour.
18. When the fluid sample reaches the desired test temperature, increase the pressure on the top pressure unit to 500 PSI (3,448 kPa) more than the back pressure. Open the bottom valve stem to initiate filtration.
19. Collect the filtrate for 30 minutes. If the back pressure rises above the initial setting during the test, cautiously reduce the pressure by opening the valve on the receiver and drawing off some of the filtrate into the graduated cylinder.
20. At the end of the test, close (tighten) the top and bottom valve stems. This will seal the cell. Failure to close the valve stems before releasing pressure (step 22) will damage a regulator by drawing fluid into it.
21. Turn off the heat switch and set the temperature controller to the lowest setting.
22. Open the outlet valve on the back pressure receiver to collect all of the filtrate in the graduated cylinder. Open the relief valve on the manifold block. This will flush the pressure lines and ensure no test fluid has flowed back into them.
23. Slowly turn the regulators counterclockwise to close off the flow of pressurized gas.
24. Remove the top and bottom retaining pins and remove the manifold block and the back pressure receiver. Drain any residual filtrate collected in the receiver into the graduated cylinder.
25. Remove the cell from the heating jacket after once again checking that the cell valve stems are tightly closed. Allow it to cool to room temperature or quick cool the cell by immersion in cool water. Pressure inside the sample cell will still be approximately 500 PSI (3,450 kPa). Keep the cell upright and cool it to room temperature before disassembling. The cell must be cool for at least one hour at room temperature or at least 10 minutes in cool water before loosening the cap locking screws and removing the cell cap.
26. Correct the total filtrate volume collected to a standard filtration test area of 7.1 in2 (45.8 cm2 ) by doubling the filtrate volume collected in 30 minutes. Record this total filtrate volume (doubled), temperature, pressure, and time.
27. Using extreme care to save the filter paper and deposited cake, place the cooled cell upright with the outlet (cap side) or filter side down. Open (loosen) the inlet valve stem to bleed off pressure from the cell body. Pressure cannot be relieved from the cell by opening the outlet valve stem as the filter cake will seal off the cell. It is a good idea to open the valve stem with the cell inside a sink or with a rag over the valve stem in order to catch any liquid that might be ejected.
28. Loosen, but do not remove, the six cap locking screws, and separate the cap from the cell with a slight rocking motion. Discard the fluid inside the cell and retrieve the filter cake.
29. Wash the filter cake on the paper with a gentle stream of water. Measure and report the thickness of the filter cake to the nearest 1/32″ (0.8 mm).
30. Clean and dry the apparatus thoroughly after each use. Inspect and, if necessary, replace all of the o-rings.
31. After all testing is complete, make sure all four heat switches are off, the temperature controllers are set to 0, the regulators are backed off completely (counterclockwise), and both Main Power switches are off.

Load Cell Option

The Load Cell option (#170-00-4S-LC) consists of four low profile precision scales designed to take more accurate measurements of fluid dispensed from filtration tests. Information from each load cell is sent to the user’s computer via USB connections. The included software records the filtrate volume in each cell and graphs it with respect to time.

1. Set up Load Cells in their designated positions on the base of the 4-unit filter press making sure that the corners of the base plates meet with their correlated posts.
   Note
   Place load cells 1 and 2 to the left of their designated support rods and load cells 3 and 4 to the right of their designated support rods.
   
2. Run the USB cables through the grommets on the front panel and into the unit cabinet.
3. Plug the USB cables into the 4-Port Hub (#170-00-4S-013).
   Actual component may vary.
   
4. Plug the Filter Press into the computer with the supplied USB cable.

Software Setup

Before running the software, install the driver as described on page 15.

1. Select Setup on the Utilities menu.
   
2. Select a COM port for each cell.
   Each load cell is assigned a COM port the first time it is connected to the computer. This COM port will remain the same unless the computer or the internal electronics of the load cell are changed.
   Repeat the following procedure for each of the four cells:
   a. Under Cell X Com, choose a COM port from the drop-down list.
   b. Click OK.
   c. On the Main Screen, locate the Filtrate Volume field under Cell X. Place a weight on the load cell and watch the field for changes.
