Removing CFCs from the air: state<br />
Customers apply the DuoCondex process to treat waste gases or to<br />
recover solvents from waste gases. The Slovakian company Elektro Recycling<br />
is now the first user to deploy this technology to purify the gases emitted by<br />
its refrigerator recycling plant. on air spoke to Plant Director Václav Trubač<br />
about his firm’s cooperation with <strong>Messer</strong>.<br />

on air: You are the first customer in Slovakia to apply<br />
<strong>Messer</strong>’s waste gas treatment process. Are you collaborating<br />
on any other joint projects?<br />
Václav Trubač: To date we have been recycling some<br />
75,000 fridges a year and the numbers are increasing<br />
steadily. So, to meet this demand, we have been<br />
cooperating with a team of <strong>Messer</strong> specialists to<br />
examine the feasibility of doubling the plant’s operating<br />
time from its original 8 to 16 hours, and even<br />
switching to continuous operation. Currently, the<br />
Elektro Recycling management team is considering<br />
expanding operating times in individual situations to<br />
boost processing capacity if required.<br />
on air: Why did you decide to collaborate with <strong>Messer</strong>?<br />
Václav Trubač: I was already familiar with <strong>Messer</strong><br />
from my previous employer – where our experience<br />
had been very positive. There we applied nitrogen<br />
in bio-technological production, particularly for<br />
isolating penicillin.<br />
At Elektro Recycling we were convinced by the<br />
DuoCondex’s ability to efficiently remove chlorofluorocarbons<br />
(CFCs) from the waste gas emitted by the<br />
refrigerator crushing plant. We purchase liquid nitrogen<br />
and gaseous oxygen.<br />
on air: Do you require much expertise on industrial<br />
gases to deploy these gases?<br />
Václav Trubač: Taking delivery of liquid nitrogen requires<br />
only minimal supervision on our part. The automatic<br />
telemetry monitoring system of the 30 cm 3 container<br />
ensures that <strong>Messer</strong> replenishes our supply of<br />
nitrogen as soon as levels in the container fall below<br />
a certain limit. We use the oxygen to dispose of mercury-containing<br />
lamps – at which we are specialists.<br />
For us the gases are an indispensable means to an end.<br />
