Pipeline conditions are realistically simulated in the Gas Hydrate Autoclave. The effectiveness of hydrate-inhibitors can be reliably checked and optimized in a pressure range of up to 200 bar /2,900 psi (GHA 200)or up to 350 bar / 5,075 psi (GHA 350).Pressure-resistant sapphire-glass windows in the Gas Hydrate Autoclaves allows the use of one or multiple boroscope-camera which enables observing the processes inside the autoclave.  Thereby gas hydrate formation can be recorded as during an experiment. Up to six autoclaves can be operated simultaneously via one PCThe Gas Hydrate Autoclaves can easily be opened and 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, are possible.
