Section 1 System Introduction

The PNR-2LM-0(1) is a sampling system designedto sample light liquid hydrocarbons.

Operation of the system centers around the PNR-2Sample Pump, and control functions that are totallycustomer supplied. The pump is mounted on astainless steel panel, with a support tray for aportable sample. The pump and panel are shown inthe diagram on the following page.

The purpose of the YZ light liquid hydrocarbonsampling system is to capture a representativeliquid sample of the pipeline product. In order forthe system to function properly, a pipeline productmust be single phase, liquid product. By properlyadjusting both the sample size and the samplefrequency, the sample vessel will fill to 80% capacityat the end of the sample period.

The system operates on a simple concept. Eachtime the sample pump is actuated a preset volumeof sample is gathered at pipeline pressure andcollected into a portable sample vessel for transferto a lab for analysis.

Section 2 PNR Sample Pump

The PNR-2P Sample Pump is a positive displacementplunger pump designed to be mounted directly on thepipeline. It has an adjustable displacement of 0.25 to1.8cc and achieves proportional-to-flow samplingthrough adjustment of the customer supplied, andcustomer controlled pneumatic signal.

As the plunger returns upward after completing astroke, the pump chamber fills with product throughthe inlet check valve. The inlet check valve is a darttype valve designed to seat on an o-ring. The inletcheck valve is spring loaded to ensure a positiveseating action after every stroke. When the pumpis actuated, the plunger moves downward, displacingproduct through the discharge check valve knownas the balance valve.

The balance valve automatically senses pipelinepressure and adjusts to ensure that product is notallowed to free-flow to the product vessel. Whenthe pipeline pressure is greater than the pre-chargepressure on the accumulator vessel, the balancevalve dart is pushed up against the seat and the tophead of the balance valve. As the pump strokes,the pressure created in the pump chamber forcesthe balance valve dart off the seat, allowing productto be pumped to the accumulator vessel. Once thepump completes its stroke, the pressure across thebalance valve equalizes and the dart is returned to asealing position by its spring.

In the event that the accumulator vessel pre-chargepressure is greater than the pipeline pressure, thebalance valve dart and seat are pushed apart by theproduct pressure in the accumulator vessel. In thissituation the check valve wafer located between thebalance valve and the sample pump acts as a backcheck to prevent the escape of product previouslycaptured in the accumulator vessel. As the pumpstrokes, the pressure created in the pump chamberforces the check valve wafer off the seat, allowingproduct to be pumped to the accumulator vessel.Once the pump completes its stroke, the pressureacross the check valve equalizes and the wafer isreturned to a sealing position by its spring.

Section 3 Installation/Start-up/Operation

Panel InstallationThe sampling system should be located as closeas possible to the pipeline. 2" U-bolt assembliesare provided to mount the panel to a 2" vertical pole.

Pneumatic SupplyA 1/4" connection on the Pump is provided for apulsed pneumatic supply (40 - 60 psi). The neces-sary regulators, solenoid valve, control functions,etc. are customer provided. The pneumatic pulse tooperate the sampler typically will require 2-3 seconddwell time to assure proper pump operation.

Pump InstallationThe PNR-2 sample pump is designed to bemounted directly to a threaded connection on thepipeline. The probe tubing should be cut such thatthe tip of the probe will be located in the center 1/3of the pipeline after installation. After the pipelinehas been depressurized, the threads on the probebody should be taped and doped and the pumpinstalled into the pipeline connection. Next youmust install 1/4" stainless steel tubing between theconnection top of the pump, to the source of thepulsed pneumatic actuation, upplied by the cus-tomer. Finally connect 1/4" stainless steel tubingfrom the discharge connection of the pump balancevalve to the connection for product in from pump onthe 5-way cross.

Pump Sample SizeThe sample size is adjustable from 0.25 to 1.8 cc/stroke. The sample size is adjusted by loosening thelock/seal nut on top of the pump and turning the volumeadjustment screw in to decrease the sample volume orout to increase the sample volume. Once the newsample size has been set, the lock/seal nut should beretightened.

Sample Pump PrimingBefore the pump begins normal operation after initialinstallation or maintenance, the sample pump must bepurged of all air in the sample chamber. The purgevalve on the sample pump is used to evacuate the airfrom the chamber and to make sure the pump is liquid-packed. If the pump is not purged before being placedinto operation, it will not function properly.

To purge the pump, open the purge valve located onthe left side of the sample pump balance valve. Theproduct supply valve can then be opened to allowpipeline product to purge the air within the pump. Onceproduct begins exiting the purge valve, close the purgevalve. The sample pump is now ready to begin opera-tion.

Purpose: The DuraSite Portable Sample Vessel permits theuser to remove a liquid or gas hydrocarbon sample from apipeline or a sampling device. This is accomplished withoutchanging the pressure of the product or exposing it to a con-taminant fluid. If properly used and maintained the DuraSitewill provide many years of safe, accurate and clean sampling.

Use: The DuraSite is a very safe device to use. As with anyequipment dealing with flammable products, it is mandatorythat a good, thorough operator training procedure be establishedprior to use.

Typical use of the cylinder would be as follows:

Step 1: (In The Lab) Connect a regulated inert gas supply tothe pre-charge valve. The product valve should be open. Bycarefully controlling the pre-charge valve and the regulator, thecylinder can be slowly charged with pre-charge gas (NOTE:This should be done slowly to prevent slamming the pistondown to the opposite end). The pressure on the pre-chargepressure gauge should be brought to a reading of 10-50 psiabove the expected pressure of the product in the field . Closethe pre-charge valve and disconnect the gas supply. Checkthe pre-charge valve, relief device, and the pre-charge pressuregauge for leaks. Any leaks should be stopped before continuing.The vessel should be placed in a padded carrying case andmade ready for field use.Proceed to EITHER Step 2, or Step 3 as required for yourapplication.

STEP 2: FOR COLLECTION OF SAMPLE VIA SPOT SAMPLEOR FROM COMPOSITEACCUMULATOR VESSEL.

2a: Connect the product end of the pre-charged sample vessel tothe product supply. (Sampler product removal valve, or Pipelinesample probe)NOTE: the pre-charge pressure gauge reading should begreater than the product supply pressure reading. If not,repeat Step 1 above.

2b: Once the vessel is connected to the product supply, it isnecessary to vent a small amount of product prior to filling thevessel. This assures fresh product and removes any air orgas when dealing with liquids. This can be done by looseningthe product purge valve a very small amount until the product ispurged. After thorough purging, the product purge valve shouldbe tightened.

2c: The product pressure gauge reading should be 10-50 psibelow the pre-charge pressure gauge reading. By carefully openingthe pre-charge valve, the pressure becomes equalized, thenbegins to drop below the product pressure. The pre-chargevalve should be carefully controlled so as to not vent the pre-charge gas too fast.

2d: When the cylinder becomes a maximum of 80% full (seevolume indicator), all valves should be closed. The productconnection is slowly broken in order to vent any trapped product.After vessel removal, all connections should be checked forleaks and the pre-charge and product valve ports capped toprevent leakage.

2e: Pack the DuraSite in appropriate carrying case to meetD.O.T. guideline, with D.O.T.paperwork and transport to lab for analysis.

STEP 3: FOR DIRECT CONNECTION TO SAMPLER.

3a: Connect the sampler discharge port to the product inletport to the DuraSite using 1/8" stainless steel tubing.

3b: (Gas sampling) Connect the pre-charge port to theDuraSite to the pipeline for pre-charge pressure (Proceed tostep 3d), or configured like the liquid sample applicationbelow. (Step 3c)

3c: (Light sampling) Pre-charge the DuraSite as indicated inStep 1, then install a pressure relief valve to the pre-chargeport and open the pre-charge valve on the DuraSite. (The pressurerelief valve should have a relief pressure setting of approximately100 psi above line pressure.)

3d: Open the product inlet valve of the DuraSite and the purgevalve on the sampler. Next open the purge valve on the productend of the DuraSite and allow product to purge all lines andconnections out.

3e: Close purge valves and begin sample cycle.

3f: At the end of sample cycle, close product inlet valve on theDuraSite and remove the DuraSite. Pack the DuraSite in appropriatecarrying case to meet D.O.T. guideline, with D.O.T. paperwork andtransport to lab for analysis.

Step 4: (In The Lab) Prior to analysis, the product should bemixed. This is accomplished simply and efficiently by invertingthe cylinder end-over-end, causing the mixing ball to fallthrough the product. Approximately 10-12 trips of the mixingball through the product assures a homogenous solution.

Step 5: The regulated pre-charge gas should be reconnectedto the pre-charge side of the cylinder. The pre-charge gassupply should remain open during analysis.

Step 6: Purging a small amount of product from the vesselremoves unmixed product from the tee, relief device, gauge,etc. The unit can now be connected to a chromatograph andthe product analyzed.

Step 7: After analyzing, the remainder of the product shouldbe dumped and the vessel properly cleaned. Normal cleaningcan be accomplished by rinsing the product end with a petroleumsolvent and flushing with acetone. If a more thorough cleaningis required, the vessel should be disassembled.

WARNING: A portable sample vessel should never be filledto more than 80%. This allows a 20% pre-charge cushion toabsorb thermal expansion of the product.Shipping: Extreme care should be taken when preparing avessel for shipment. Both valves should be capped to preventpossible leakage. The vessel should be placed in asnug-fitting, well-padded and durable case. All applicableDOT regulations should be adhered to.
