ABB's OPT800 Lime APC solution preferred by Andhra Paper; stock jumps ~2%

ABB India Limited informed that Andhra Paper Limited (APL), India’s largest integrated pulp and paper manufacturer, has installed an ABB advanced process control (APC) solution in their lime kiln at their Rajahmundry mill.

ABB India has integrated their OPT800 Lime APC solution into APL’s existing ABB Ability System 800xA distributed control system to assist in reducing the energy demands of the highly interactive lime kiln production process (DCS).

OPT800 Lime allows for greater control over the lime production process. Lime mud is calcined into quick lime, which is then processed to produce white liquor in the kraft recovery process. Because the process is endothermic, a significant amount of energy is required in the calcination process, which is one of the major contributors to the mill’s energy costs.

At its heart, OPT800 Lime employs a kiln process model to accurately predict process variable interactions and make real-time adjustments to process changes.

This results in a smooth and stable pulp mill operation and uniform lime quality, as well as lower energy consumption and emissions, increased reburned lime availability and decreased residual carbonate variations.

Post this development, ABB India’s counter was trading at Rs2,712.10 per piece, up by 1.66% from its previous closing of Rs2,667.90 on the BSE. The scrip touched intraday high and low of Rs2,740.50 and Rs2,679.25 respectively.
