Calsep Joins Tulsa University Hydrate Kinetics JIP

In June 2008 Calsep joined the Tulsa University hydrate kinetics JIP . The JIP membership gives Calsep access to experimental hydrate kinetic data recorded in the Tulsa University flow loop facility since 2004. As part of the JIP Calsep has to deliver a flow loop hydrate kinetic simulator.

FLOWASTA VALIDATION

Flowasta can simulate hydrate growth in pipelines using the hydrate kinetics growth model of Skovborg and PVTsim thermodynamics. Calsep has already validated the Skovborg model using experimental data for agitated tanks. The next step is to validate Flowasta in flowline scenarios.

This is the basis for Calsep entering as a sponsor in the Tulsa University hydrate kinetics JIP where “The overall project objective is to conduct experimental flow studies […] to quantify the amount of hydrates that could form in a pipeline and determine whether the hydrates formed would block a pipeline” . Such data will play a central role in the Flowasta validation work to come.

FLOW LOOP OPERATION AND SIMULATION

To learn how the Tulsa flow loop is operated and how to interpret the loop data Jacob Sonne from Calsep visited Tulsa University for one week in early July this year. During this very fruitful visit the Tulsa University hydrate group and Calsep also agreed on the best way to simulate the flow loop.

NEXT JIP MEETING

The next JIP Advisory Board Meeting will be held in Tulsa September 16th 2008. Here the Tulsa University hydrate group will present the progress in the project. Calsep will outline its modeling work and how Flowasta is to be modified to enable flow loop simulations. Once the loop simulator is functional, Flowasta can be benchmarked against the experimental flow loop data.
