PIK-WFL Wax/Deposition Testing Facility

PIK-WFL is a closed, isolated hydraulic system operating under overpressure, which prevents sample degassing and ensures the validity of experiments. The circulation loop is designed to simulate solid-phase deposition in a pipeline section. The refrigerant cools the test pipe section, while the main system maintains an elevated temperature. This creates a temperature differential that initiates deposit formation. The measured values of the pressure differential across the capillary and the inlet/outlet temperatures of the loop allow for the calculation of fluid viscosity, changes in flow area, deposit thermal conductivity, and WAT (Wax Appearance Temperature).

The precise dosing system allows the inhibitor to be introduced into the test loop directly during testing.

Experiments can be conducted in either open-loop or closed-loop mode. In open-loop mode, the sample is directed from Tank 1 to the waste tank 2. Closed-loop mode is suitable for long-duration experiments. In this mode, the sample is recirculated back to sample tank 1.

The system supports both automatic and manual control modes, enabling both standard and custom specialized experiments.
