Air Liquide supply air separation unit to Röhm


Following the signing of a long-term contract in 2004, Air Liquide has installed a new air separation unit to Röhms facility in Germany.

The new unit with a production capacity of 320 tonnes per day of oxygen was commissioned in order to fulfil the growing demand for oxygen caused by the increased demand in sulphuric acids.
