Operational History

Operational History
The Glenn Extreme Environments Rig successfully demonstrated the ability to reach and operate at Venus surface conditions for 24 days in November 2014. A custom gas mixer was used create the Venusian atmosphere containing 96.5% CO2, 3.5% N2, 180 ppm SO2, 23 ppm CO, 0.4 ppm HCl, 0.05 ppm HF, 4.4 ppm OCS and deliver it to the vessel.

After 2.5 days of heating at 7C/hr., the vessel reached Venus surface conditions of 460C and 1334 psia while maintaining a leak free seal.

The system boundaries were tested by increasing temperature and pressure to 470 C and 1400 psia where the vessel remaining for 24 days. Over this period of time, the heaters and setpoints were varied to gain operational experience and knowledge of the system.
