Arauco’s operational efficiency ensured with new economiser

Arauco is a global manufacturer of forest products with operations around the world. It offers a comprehensive selection of composite panels including MDF, particleboard and HDF, premium plywood, millwork, lumber, and wood pulp.

In Argentina Arauco’s Puerto Piray plant produces MDF and operates a biomass plant which uses eucalyptus and pine as fuel to produce energy and has operated a boiler with an economiser supplied by E. Green & Son Ltd since 1980.

After more than 40 years of round the clock usage, some of the economiser’s tubes had deteriorated so Arauco needed to replace it to ensure efficient operations could be maintained.

Green’s, which is part of Heat Exchange Group, were asked to supply the replacement unit, as a trusted designer and manufacturer of finned tube economisers.

While the heating surfaces remained the same as the original 1980s design, the new unit required updates to the mechanical design to meet current ASME I standards.

From receiving the order, Green’s expert design, engineering and manufacturing teams designed the unit which comprised finned tubes, supports, headers and casing and manufactured it in their Wakefield factory in less than 5 months.

Esteban Guevara, Category Manager MRO at Arauco Argentina said: “Our previous economiser which was made by Green’s over forty years ago provided decades of reliable service and we are confident that the new unit their team made will perform similarly.”

This was the latest in a number of projects that Green’s has worked on for Arauco having previously supplied economisers and flue gas coolers for other plants in Argentina and Chile.
