In process metallurgy, the melting and refining of metals within PAM processes, one is facing an ongoing shortage of helium. This is undeniably a major challenge for the valuable and non-renewable resource of helium. A study on the subject summarizes the ongoing bottlenecks in the global helium supply since 2006: From one shortage to the next. (Source: bgr.bund.de)

However, according to another market study, the global PAM market is showing steady and strong growth. This trend is expected to continue until 2030.

The perfect way to counteract the helium scarcity is a Helium Recycling System.

The helium used in the plasma arc melting process (PAM) is highly contaminated. However, the rare gas can be made usable again! Helium recycling with ReiCat can take place during and after melting.

The system shown has a volume of around 690 Nm³/h. It removes dust, oil, and chlorine and converts hydrogen. This is followed by the elimination of nitrogen and oxygen. In this way, the helium quality can be improved from 4.0 to 6.0 (99.9999 %). Our Closed-Loop System prevents any emissions. Redundant online gas analysis for O2, N2, Cl2, and H2O ensures a high gas quality.

Thus, ReiCat’s Helium Recycling ensures a reduction of the required gas of up to 98%, which is why the plant amortizesProz in no time and drastically reduces the CO2 footprint of a PAM process.
