Gas Hydrate Autoclaves GHA 200 & GHA 350

The Gas Hydrate Autoclaves GHA 200 and GHA 350 by PSL Systemtechnik are hydrate test cells for research the effectivity and efficiency of kineticand thermodynamic gas hydrate inhibitors, as well as anti-agglomerates. 

Pressure-resistant sapphire-glasswindows in the Gas Hydrate Autoclaves allows the use of one or multiple boroscope-camerawhich enables observing the processes inside the autoclave.  Thereby gas hydrate formation can be recorded as photo or videoduring an experiment. Up to six autoclaves can be operated simultaneously via one PC. 

The Gas Hydrate Autoclave GHA 200 is equipped with one borescope camera, it is mounted in the autoclaves' head and observes the sample surface from topview.

The new developed Gas Hydrate Autoclave GHA 350 has two additional cameras on the sides. With these cameras the hydrates behaviour can be observed in the liquid phase(bottom side camera) as well as at the phase boundary(upper side camera).

The autoclaves are all equipped with an integrated magnetic stirrer to simulate turbulent mixing conditions by the use of stirrer bars. Much higher turbulences and shear forces are accessible with the overhead stirrer in combination with different types of rotors.

The overhead stirrer is connected to a torque sensor. By this you can perform torque measurementsand get conclusions of the samples viscosity changes. The GHA 200 can be used with either camera or overhead stirrer, changing from camera to overhead stirrer (and vice versa) can be done between experiments. With the GHA 350 you can use three cameras and overhead stirrer simultaneously.

The Gas Hydrate Autoclaves can easily be openedand closed by a specially designed mechanism. An integrated double jacket, temperature and pressure sensor, as well as the integrated stirrer enable a full control of experiments. Even small leakage losses are prevented by double seal sets. Thus, long-run experiments of 30 days or longerare possible. The insulation of the Gas Hydrate Autoclave supports a quick heating and cooling as well as good temperature stability at test conditions.

A practical display-box(D-Box) is available optionally. It provides the pressure values of up to six Gas Hydrate Autoclaves at a glance. 

On request we adapt the Gas Hydrate Autoclaves to your requirements.
