Praxair has secured the start-up of a new 125 tonnes per day non-cryogenic vacuum-pressure-swing-adsorption (VPSA) plant at the Montes del Plata pulp mill.
Under a long-term contract, Praxair will supply gaseous oxygen to the mill located in Punta Pereira, Uruguay.
In response to growing environmental regulation, pulp mills are eliminating the use of chemicals in the bleaching process. Oxygen delignification reduces the use of chemicals in the plant resulting in operational cost savings, environmental benefits and enhanced yield in pulp production.
“Oxygen is a critical product in processes that help pulp and paper manufacturers increase productivity and improve environmental performance,” said Domingos Bulus, president of Praxair South America. “It is our mission to develop innovative applications technologies that produce environmental benefits and drive business growth. With this in mind, we have developed and implemented state-of-the-art applications to ensure the safe, efficient and reliable delivery of oxygen to the Montes del Plata plant.”
