ANDRITZ to supply new pickling and galvanizing line and acid regeneration plant with ECOmode to Prosperity Tieh, Taiwan

The ANDRITZ scope of supplies and services includes the terminal equipment, a laser welder and a side trimmer at the inlet, a scale breaker, the pickling section, skin-pass mill #1, a direct-fired furnace (DFF) for heat-to-coat operation, the galvanizing section, skin-pass mill # 2 with tension leveler, the chemical coaters with drying section, and the electrical and automation equipment for the complete line.

The delivery will include the following sustainable ANDRITZ solutions:

• A new acid regeneration plant (ARP) to recycle the waste acid from the pickling line – including the proven ANDRITZ ECOmode process which reduces CO₂ emissions from the ARP by 25%.
• A heat recovery system for the furnace that will use hot exhaust gases from the furnace to heat the air needed for the drying process in the coating section.
• After heat recovery, the main off-gas streams from the DFF and ARP are combined for exhaust gas treatment using a DeNOx system to minimize the NOx levels in the exhaust gas. The dryer exhaust gas system in the post-treatment section is equipped with VOC treatment (volatile organic compound emissions).

With ANDRITZ’s state-of-the-art, sustainable technologies, this line will produce hot-dip galvanized (GI) or ZM-coated /(zinc-aluminum-magnesium) flat steel. ANDRITZ will also provide consultancy on the production of ZM-coated material.

This order confirms the long-lasting, good relationship between ANDRITZ and Prosperity Tieh. In 2004, ANDRITZ delivered and successfully commissioned a push-pickling line with ARP and in 2018, a 4-high cold-rolling mill to Prosperity Tieh. Additionally, ANDRITZ has performed various upgrades and modernizations on existing lines.

Established in Taiwan in 1985, Prosperity Tieh Enterprise Co. Ltd (PTEC) evolved from a traditional stripping, shearing, pipe and washer pressing mill to a manufacturer of professional hot-dip galvanized and pre-painted steel.
