Wax Flow Loop

Examine wax deposits in pipelines

Wax Flow Loop WL

The fully automated Wax Flow Loop (WFL) from PSL Systemtechnik is a compact laboratory measuring device for analysing the precipitation and deposits of waxes, paraffins and asphaltenes in pipelines.

All important features of WFL

Application Areas of Wax Flow Loop

Wax, paraffin and asphaltene deposits

Wax crystallisation

Wax dispersion

Testing of pipeline coatings

Develop and optimise inhibitor chemicals and solvents

Quality control

Design of Wax Flow Loop

The Wax Flow Loop simulates the conditions in the pipeline using a model pipeline through which the sample is channelled. During a test, the sample is preheated to the desired initial temperature and pumped through a temperature-controlled pipeline. The powerful cooling and heating systems enable short tempering times and therefore faster test results.

With the Wax Flow Loop, you can use one device to analyse the development of wax deposits on the inner walls of the model pipeline via the differential pressure and the formation of wax crystals in the medium itself via the differential temperature.

The differential pressure and the temperature of the medium are continuously measured by sensors above the temperature-controlled pipe section. The value curves are displayed on the screen in real-time diagrams. This makes it possible to make precise statements about the development of wax deposits and crystal formation in the medium as early as the test runtime. Shock cooling can be switched on to maximise the deposition effects and shorten the duration of the experiment.

Thanks to the compact design, a footprint of only 90 x 60 cm is required.

Wax Flow Loop 20040 High Pressure with Thermostat

Small sample quantity - Many test options

Only 50 ml of sample amount are sufficient to come to conclusions about the efficiency and effectiveness of wax inhibitors.The Wax Flow Loop also provides the possibility to assay the efficiency and effectivenes of dissolvers. This feature allows you to execute Pipeline Restart Tests and Yield Stress Tests.

Flexible test conditions

The flexible Wax Loop offers various possibilities for experiments. So the test capillarycan be exchanged and thus be varied in length and diameter. This way, different approaches for test runs are permitted. Shorter test capillaries enable to observe effects in differential pressure, as well as in differential temperature. By changing the pump rate you can measure the deposition at different shear rates.

Experiments can be run with open or closed loop mode. In open loop mode the sample is lead to a waste container. The closed loop mode is suited to run long-time experiments. In this mode, the sample is pumped back to the sample container.

The integrated control-PC and the operation software WL_Control enable an easy usage of the instrument. The software supports the definition and management of standardized experiment runs. So repeated and similar tests can be run time-saving and in quick succession.

To clean the test capillary from remains of chemicals, it is possible to execute an automatic cleaning after every test run.

We can adapt the Wax Flow Loop to your requirements.
