PROJECTS
Excellent ROI with Paper Machine Optimization in South African Customer
-
The paper machine performance in terms of Product Quality and Runnability has improved dramatically
-
Improved DCS control utilization from 57% to 84%
-
Improved loop performance index about 25%
-
Improved Stock Stability which provided more stable stock to paper machine by 67%
-
Improved the QCS Response index which provided more stable by 69%
-
Basis weight and Moisture variability and improved recovery from upset by >70%
Successful Auto Grade Change Tuning reduces >50% grade change time in Indonesian Customer
>50% reduced grade change rejects and reduced rejections due to upset, machine start up etc
OPTIPID Optimization Services Guide further Blending Control improvement at South Indian Customer
The Blending performance in terms of steady state variation and transition time to target has improved
-
Improved all the loop performance by > 70%
-
Mixing Chest level variation is reduced from peak to peak +- 1% to +/- 0.15%.
-
Improved stock stability which provided more stable stock to paper machine
-
Control valve life must be improved by reducing unnecessary oscillations.
Progress exactly according to plan - Sheet Break Analysis
The major issues for the instability of the Paper Machine are identified as
-
Wet end variability, which was causing the product variability and also taking longer time to stabilize after sheet breaks.
-
Chemical variability, which was causing product chemistry and variations and also can create sheet breaks.
-
Vacuum variability, which was causing instability in retention, drainage etc. and can create fluctuation in the sheet draw, tension which will definitely causing breaks.
-
Headbox variability, which was causing instability in head box stock delivery and can cause breaks.
-
Steam and Condensate variability, which was causing instability in moisture variations and can cause sheet breaks.
