Plasma arc melting (PAM) and zero emissions – do they go together?

Avoiding emissions with helium recycling

Titanium. Even in low concentrations, it gives steel high strength, toughness, ductility and malleability. Titanium alloys are particularly important in the aerospace industry; its low weight makes titanium indispensable for parts subject to extreme stress.

Titanium is produced in arc furnaces, specifically by means of plasma arc melting (PAM). A gas such as argon or helium is indispensable for this melting process in an inert gas atmosphere. Helium is a gas that is both rare and non-renewable. This means that the contaminated gas is not only a problem for the environment. Fluctuating availability is the next challenge. This is how you can remedy the situation:

With ReiCat’s special helium recycling system, gas consumption can be reduced by up to 98%. You can achieve a gas quality of up to 6.0 (99.9999%) even with originally lower values, all during operation. A wide range of impurities, dust and moisture are removed. And yes: zero CO2 emissions are achieved. All this with very good amortization times.
