The Cold Finger is used to examine the wax content of crude oil and condensate. The PSL Coldfinger CF 15 is equipped with up to 15 measuring places for multi-place testing. It facilitates simultaneous testing of different chemicals on a single sample or testing of different inhibitor concentrations with the same sample.The Cold Finger is simulating the temperature difference, a cooled part (finger) is inserted into the stirred and heated oil. The contained waxy components start to precipitate on the surface of the cold finger cell. By weighing the deposition after a time at a set temperature, the deposition rate can be calculated. The final amount of deposition gives the total wax content.The wax deposition rate depends not only on the finger temperatures, but on sample temperature and stirring speed, too.


Features:

• 15 measuring places for simultaneous test

DySL - Stress-Test of Oilfield Chemicals : The Dynamic Stability Loop (DySL) is designed for testing oilfield chemicals on long term stability under most rigorous conditions in laboratory. The DySL combines multi-loop testing of viscosity and filter blocking tests for low and high temperature under pressurized conditions.

In respect to extensive testing demands, the DySL is specially designed for multiple loop test runs.It comprises up to 6 test loops for parallel testing of different alternatives oilfield chemicals or different product types.Each loop is operated seperately Cleaning and refill is possible while other loops are still runnings.

Features:

• Up to 6 pressurized test loops.
• Hot and cold bath for stress test.
• Computer controlled, automated data acquisition.
• Easy handling
• Open and closed loop testing
• Small sample volumes.

 

Applications:

• Observation of scale in pipelines and water pipes.
• Development of inhibitors.
• Optimization of inhibitor concentartion.
• Optimization of water treatments.
• Quality control.

Note: Price may vary depending on configuration & accessories.

Wax Flow Loop by PSL Systemtechnik is a compact laboratory instrument to research deposition effects of waxes, paraffins and asphaltenes in pipelines.
The Wax Flow Loop simulates pipeline conditions by a test capillary, which the sample is pumped through.Only 50 ml of sample amount is sufficient to know 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 to execute Pipeline Restart Tests and Yield Stress Tests.The Wax Flow Loop is an instrument to examine wax deposition to the inner wall of the capillary via differential pressure and wax crystallisaion in the medium itself via differential temperature.The differential pressure and -temperature are continously measured and displayed as real-time diagrams on the monitor . This allows precise conclusions about development of wax depositions and crystallisation in the medium during a test run.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.

Features:

• Fully automated
• Exchangeable model pipeline
• Small sample volume is requied (50ml)
• Shock-cooling effect to maximise deopsition effect & shorten test time
• Real time diagrams

Applications:

• Research on deposition of wax, paraffin & asphaltene
• Analysis of wax crystallisation
• Testing of wax dispersants
• Testing of pipeline coatings
• Development & optimization of inhibiting agents & dissolvers
• Quality control

Note: Price may vary depending on configuration & accessories.
