Selective Non-Catalytic Reduction (SNCR)

  • Application of innovative solutions for NOx abatement to achieve significant savings in capital and operating costs
  • This solution may be applied in combination with other INERCO NOx reduction technologies, hence resulting in the optimisation of both results and investments costs
  • Cutting-edge technology with differential capabilities to enhance the operation of conventional SNCR solutions:
    • Zonal reagent injection based on local combustion conditions characterised by ABACO-Opticom technology and pyrometry
    • Possible closed-loop operation
    • Design of nozzles to achieve maximum injection coverage based on CFD fluid dynamic studies
    • On-line monitoring of ammonia slip
    • Adaptability to high temperature scenarios and substoichiometric conditions
  • Additional Services:
    • Optimisation of existing SNCR systems
    • Development of tests with a portable pilot plant for reagent injection to assess the scope and potential of SNCR technology in any combustion facility in terms of NOx reduction and associated costs
  • Main results::
    • NOx reductions: 30-50%
    • Minimisation of ammonia slip
    • Reduced reagent consumption
    • Reduction of investment costs in the range of 30%-50%
    • Reduction of operating costs in the range of 40%-60%
