Single-Phase Paraffin Deposition Flow Loop

Single-Phase Paraffin Deposition Flow LoopThe single-phase paraffin deposition flow loop designed and constructed by PetroCanada and later operated by the Alberta Research Council was donated to Tulsa University in 1995 for use in a paraffin deposition JIP. This 200-foot long, horizontal, 1.7-inch diameter, fully jacketed flow loop permits testing a variety of crude oils under laminar and turbulent flow conditions. Outstanding instrumentation, precise temperature control and state-of-the art data acquisition generate outstanding data for evaluating and developing improved deposition models.

Multiphase Paraffin Deposition Flow Loop

Multiphase Paraffin Deposition Flow LoopAs part of the Paraffin Deposition JIP focus, a new multiphase flow paraffin deposition facility was constructed. The test section is 2-inch diameter stainless steel, high pressure (1,000 psi), fully jacketed, 75-foot long, and inclinable (0° to 90°). A waxy crude oil-natural gas mixture flows in the inner pipe, countercurrent to a chilled glycol mixture in the jacket annulus. State-of-the-art instrumentation, temperature control and a distributed data acquisition system permit obtaining outstanding data.
