Business Challenge

Operators struggled to consistently achieve ultra-high purity levels (10 ppb) required for semiconductor-grade products. Due to concerns over potential purity loss, they were reluctant to adjust ASU loads, especially during fluctuating demand. This led to frequent product venting and yield loss, as manual control lacked the precision and confidence needed for real-time optimization

Solutions Deployed

Automatic Sequence Transition

  • Automatic “one-button” ASU start-up from cold condition
  • Automatic transition between single & dual main air compressor mode

Linear Model Predictive Control

  • Optimization of efficiency & change plant load

Benefits

  • 40% reduction in power consumption, significantly lowering operational costs.
  • 30% decrease in GAN blow-off, enhancing product yield and process efficiency.
  • 25% faster Plant start-up,  improving responsiveness.
These improvements collectively delivered an annual savings of $2.5M USD.
