Expertise: Simulation and Optimisation
 With pre-commission testing of new equipment - and improving the efficiency of existing plants - Beca AMEC's simulation and optimisation expertise helps ensure the overall project performs to design (or better) specifications.
In an increasingly competitive market, pulp and paper mills are under pressure to improve efficiency, produce more (often with increased product diversity) from existing equipment, under tighter raw material and environmental constraints. Selecting the best strategy for achieving these goals can be fraught with risks, but Beca AMEC has a range of technical skills, capabilities and modelling techniques that simplify the decision-making. They allow plant managers to analyse processes more easily, improve designs, speed up initial start-ups, test plant control and improve operators' skills. The selection of Beca AMEC's tools includes Mass and Energy Balances, Dynamic Process Modelling, Process Control Analysis, Capacity Modelling and Mill Optimisation. Capacity Modelling and Auditing establish the true capacity of a plant. Benchmarking, duration curve analysis, and bottleneck identification establish the capacity gains/reductions that occur by changing the process, product mix and other variables. Mill optimisation is a proven methodology Beca AMEC uses to gain the maximum capacity and /or efficiency from a complete mill or its individual plants. The methodology uses performance audits, benchmarking and problem solving to identify capacity and quality gains. Capex reviews determine which capital expenditure option provides the biggest capacity or quality gain, while production planning verifies that the proposed sales demand can be met. These techniques allow management to quantify capacity gains resulting from different process or operational changes, and identify the capex required to achieve different targets.
