Multi-effective Evaporator – Steam Optimization

Challenge

  • Includes frequent thermal breakdowns due to fouling

 

  • More than required steam consumption leading to sub-optimal operations

Solution

  • Create a soft sensor for overall heat transfer coefficient and set alarm limits
  • Benchmark and compare the real-time steam consumption with respect to the ideal consumption

Result

  • Steam optimization by ~ 15-20%

 

  • Reduction in unplanned maintenance by 55-60%

 

  • Reduction in cost of maintenance by 12-15%
