ANDRITZ services for white liquor plants

The challenge

The challenge for every mill is to continuously improve the overall production efficiency with lower life-cycle costs and reduced environmental impact. In the white liquor plant, the main challenges center around efficient conversion of green liquor to white, the purity of the cooking liquors, energy efficiency, and reduction of the volume of dregs to landfill.

The solution

ANDRITZ PULP & PAPER value-added services range from single replacement parts to comprehensive Overall Production Efficiency (OPE) agreements for a specific process, or an entire white liquor plant. To achieve higher capacity, higher product quality, lower costs, and extended equipment life, we provide rebuilds, upgrades, and optimization services for existing equipment. To determine the improvement potential of your processes and equipment, and to prioritize the key areas for further focus, we conduct inspections, audits, improvement studies, and other field services. To complement our service capabilities, we manufacture and stock a full range of replacement parts and engineered wear products for ANDRITZ and other OEM machines. We can assist in shut-down planning, on-site coordination, supervision, and with the actual shut-down work. We also offer specialized operator and maintenance training.
