Data Analytics for the Pulp & Paper Industry

Reduce Production Costs with Data Analytics Software

Achieving a high rate of pulp and paper production while still maintaining consistency and quality can be a challenge. The pursuit of higher productivity puts a lot of stress on the equipment. Interruptions can be very costly, and a high variability is bad for quality. Thus, any measures to keep production consistent – or even improve it – without exhausting or damaging the hardware can mean big savings.

Data analytics software offers an alternative way for pulp and paper mills to reduce costs and improve quality without purchasing expensive new equipment. Using software to achieve process optimization and control can bring big returns – including reduced waste, improved efficiency and prolonged equipment lifespans.

Optimize Production Processes

SIMCA® Multivariate Data Analysis (MVDA) software provides a way to adjust production processes in order use raw materials more efficiently, increase output, and reduce wear and tear on equipment. SIMCA® uses historical process data such as yield, output and quality parameters to create a model of the production process at optimal performance. It can also help optimize steam and power generation, including recovery boilers, resulting in additional savings on fuel, as well as keeping emissions under control.

Keep Processes Under Control

One of the most effective ways to ensure your processes stay within their ideal parameters is with real-time process monitoring and control. Being able to take corrective action immediately helps reduce waste and improve efficiency. With SIMCA®-online, you’ll gain confidence in your production processes and achieve more consistent product quality.

Achieve Predictive or Even Prescriptive Control

Another advantage of real-time monitoring is predictive control. SIMCA®-online is able to predict how a process is developing and determine whether it’s deviating from an optimal model. This provides an opportunity for prescriptive action, changing the variables early on, which can be done automatically in the form of a closed loop, or manually by an operator.

Data analytics software costs far less than investments in capital equipment, typically doesn’t require permits and is quick to implement compared to installing new equipment.

Capital Investments (Compared to Software)

  • Entail extensive formal budget reviews and high costs
  • Involve extensive time to implement with multiple vendors
  • Need permitting and regulatory requirements may apply
  • Demand new personnel and / or extensive training
  • Slow or interrupt operations during implementation

ROI and Savings Results

The return on investment (ROI) for pulp and paper mills that have implemented SIMCA® and SIMCA®-online for process optimization and control is six times to nine times or more, per year. In short, companies can save millions of dollars in just a few months with the software.

Three Pulp and Paper Company Examples

Improved Recovery Boiler Efficiency

The goal for one pulp and paper company was to improve recovery boiler efficiency and save fuel cost.

  • The plant manager had calculated that a 1% improvement in black liquor solids content through better evaporator performance was worth over $200,000 a year in saved fuel
  • By improving the process with SIMCA®, the increase in solids achieved was 0.5%
  • Expected improvements over the next year were estimated at 1 - 2%

Real-Time Assessment of Product Quality

Two paper specialty companies implemented SIMCA® and SIMCA®-online for real-time assessment of product quality.

  • By assessing quality in real-time, and thus reducing the dependence on lab tests, the company was able to reduce start up time when doing grade changes by up to 50% while increasing output by up to 25 tons on one machine
  • This has led to savings close to €300,000 on one machine
  • In another case, the number of failed trial runs for new customers or new products could be reduced to 0 out of 50 runs, thus saving considerable cost and time for rework as well as being beneficial for the company’s reputation

Save On Chemicals Consumption

A customer reduced soda waste and lowered material costs using SIMCA®-online

  • Controlling the pH of the clarifier allowed exact and timely dosing of sulfuric acid to maintain constant, ideal level
  • Savings of sulfuric acid and soda loss were calculated to be in excess of USD 120,000 per year

Optimize and Control Processes

Data analytics software helps you optimize your processes and keep them under control during manufacturing.

  • Reduce unplanned downtime
  • Improve overall equipment efficiency (OEE)
  • Improve raw material utilization
  • Monitor a single control chart instead of multiple screens
  • Identify defects quickly
  • Model strategies and predict outcomes

Reduce Unplanned Downtime

You can use data coming from your instruments and analyzed in a multivariate way to manage the long-term operational health of production equipment, reduce unscheduled downtime, and prevent breakdowns. With a statistical analysis of all the factors that lead to wear and tear, you can get insights into the operational settings or processes most likely to extend the life of equipment or shorten downtimes between processes, and even implement predictive maintenance.

Improve Overall Equipment Efficiency

Overall equipment efficiency (OEE) is the gold standard and a best practice for measuring manufacturing productivity. It provides an objective measurement for the percentage of manufacturing time that is truly productive. By measuring OEE and analyzing underlying losses and bottlenecks, you will gain important insights on how to systematically improve your manufacturing process.

Improve Raw Material Utilization

The right data analytics tool can help you assess the composition of chemicals, minerals and other raw materials to make sure they meet production requirements. This can help prevent inferior raw materials from being used that could affect the quality of your final product or ruin batches. It can also help you find the right volume, temperature, composition or any other relevant property of raw materials to optimize your process and produce the best quality product with the least waste.

Get a Unified Control Chart

With typical process monitoring applications, your operators will have a number of different control charts they need to watch and monitor for deviations. Combining multiple charts into a single control chart to monitor all variables simultaneously and get alarms when a process starts deviating from the optimal path can be a huge benefit, especially when you are operating with less than normal staff. Drill-down capabilities will allow you to identify root causes for deviations immediately.

Identify Defects Quickly

With statistical process monitoring in place, you’ll be able to more quickly identify any defects in your products, materials, equipment or processes. Ultimately, that will mean an improvement in your overall production quality, reduction in process deviations and fewer ruined batches.

Model Strategies and Predict Outcomes

The multivariate analysis model provides a basis for predicting quality parameters over time. It lets you predict the final critical quality attributes with a high degree of confidence. Manufacturers can use advanced data analytics to compare and measure the effect of various production inputs – often finding surprising and unexpected dependencies that are impacting output.
