Intro

This test determines the Partially Hydrolyzed Polyacrylamide (PHPA) concentration in mud filtrates. The test involves the measurement of the rate of ammonia generation while the mud filtrate is heated in the presence of sodium hydrox-ide solution. The ammonia is removed from the reaction vessel with a slow air purge and detected with a Dräger-Tube™. The approximate concentration of PHPA is determined by measuring the time required for the Dräger-Tube™ to turn blue. The procedure can be used to analyze all filtrates except those containing some types of lignosulfonates and acrylate filtration control additives.

Procedure

The unit must be calibrated (see page 4) in order to obtain accurate results.

1. Be sure the equipment is clean and dry.

2. Connect a power source to the power inlet on the back of the case. If you are connecting to a 230 VAC power source, be sure to use the supplied step-down transformer to avoid damaging the equipment.

3. Plug the pump and the hot plate into the two power outlets on the back of the case.

4. Obtain 10 mL mud filtrate using an API filter press.

5. Remove the reaction cylinder from the stainless steel beaker. Fill the stainless steel beaker with 800 mL of water and place it on the hot plate. Heat the water to 190° – 194°F (88° – 90°C).

6. Break both ends of the Dräger-Tube™ and insert it into the tubing on the far left-hand side of the case. Make sure the numbers increase from bot-tom to top. Attach the outlet tubing from the glass 250 mL cylinder.

7. Fill a 50 mL syringe with 40 mL of 20% Sodium Hydroxide (NaOH) solu-tion. Inject the NaOH into the reaction cylinder.

8. Add 10 mL of mud to the cylinder and seal it. Attach the cylinder to the apparatus.

9. Start the air pump and timer.

10. Record the time required for the blue color to reach the “70” mark on the Dräger-Tube™. Compare this time with the times on the calibration chart. Report the concentration of available polymer as pounds per barrel of product.

11. To clean the apparatus, remove the reaction cylinder and rinse it with water. The other cylinder may be attached directly to the air pump and flushed with air for several minutes. Both glass cylinders should be thor-oughly dried before the next test.

Calibration

The procedure is performed with an aqueous solution containing .5 g Partially Hydrolyzed Polyacrylamide (PHPA) polymer in 350 mL of water. Run the test on 10 mL of this fluid mixed with 40 mL NaOH. The air flow should be ad-justed using the adjustment at the base of the flowmeter and the excess flow valve, so that the time required for the blue color to reach the “70” mark is 24 to 25 minutes. This will require a flow of approximately 100 cc/min. There is some batch-to-batch variations in the Dräger-Tubes™, but one calibration should be sufficient for all Dräger-Tubes™ having scale lengths of 51 to 56 mm. The unit should be recalibrated for Dräger-Tubes™ having scale lengths less than 51 or greater than 56 mm. When it is possible, always use Dräger- Tubes™ from only one batch to obtain the best accuracy. Batch numbers for Dräger-Tubes™ are located on the outside of each box. All Dräger-Tubes™ have an expiration date stamped on the outside of the box and should be used prior to this date.
