PSL systemtechnik's Sapphire rocking cell is a laboratory instrument which provides to research on low dosage hydrate inhibitors (LDHI), anti-agglomerates (AA) & kinetic hydrate inhibitors ( KHI). Deepwater conditions can be simulated with the up to 200 bar (2,900 psi) covering test cells. Depending on the setup it is possible to use up to 20 sapphire cells at the same time. With the ball run-time measurement the pumpability of the dispersed gas hydrate can be tested and conclusions about viscosity changes can be drawen. The measuring principle of the Rocking Cell is based on the constant tilting (rocking) of temperature-controlled, pressurized test cells (rocking cells). By tilting a inserted ball rolls through the entire length of the test cell and mixes the contained fluid-gas mixture. The ball movement induces strong shear forces and turbulences inside the test cell which simulated the conditions inside a pipeline. A typical experiment can be divided into the three phases flowing conditions, shut-in and restart flowing conditions.For testing the test chambers are filled with a sample fluid (water or other) and a certain amount of inhibitor. The test chambers are cooled down to a given test temperature. Subsequently, the central gas supply is used, to fill each chamber to the individually required pressure of up to 200 bar (2,900 psi) for multiple tests with different starting conditions. As alternative all chambers could be run with the same pressure.
