ABB and Andhra Paper (APL) have joined hands. Andhra Paper has deployed an ABB advanced process control (APC) solution at their Rajahmundry mill’s lime kiln. To help reduce the energy requirements of the highly interactive lime kiln production process, ABB India has integrated their OPT800 Lime APC solution into APL’s existing ABB Ability System 800xA distributed control system (DCS).
OPT800 Lime enables tighter control of the lime production process. In the kraft recovery process, lime mud is calcined into quick lime which is then further processed to create white liquor. The process being endothermic, a great deal of energy is required in the calcination process and is one of the leading contributors to mill’s energy costs.
ABB India is a leading global technology company that energizes the transformation of society and industry to achieve a more productive, sustainable future.
