Plants retrofits

LAB Service is a specialist of existing installation retrofit in need of performances improvement.

LAB Service offers complete solutions with short lead time, less than 12 months, for flue gas treatment, heat recovery and combustion improvement with more than 30 years of experience in retrofit projects and a list of references including all available technologies.

Our solutions include:

  • Adapted process design
  • Detail engineering
  • Procurement
  • Erection
  • Commissioning and fine tuning

Key technical areas of LAB Service retrofit catalog

  • Combustion optimization, air control and CO management
  • Reagent consumption optimization (such as patented process VapoLAB™)
  • Utilities consumption reduction (Zero Water release)
  • NOx reduction improvement (such as with patented process TermiNOx, SNCR, SCR)
  • Emission Limit Value reduction


LAB has developed a mobile demonstration unit DemoLAB which can be easily installed on any site. The DemoLAB demonstrates the efficiency of our proposed technologies. Fed with installation continuous raw gas, DemoLAB is a complete industrial Flue Gas Treatment system addressing acid gas abatement, de-dusting, Nox and dioxins reduction with the same efficiency than a scale 1 installation.

  • 40% Reagent consumption reduction and availability increase from 60 to 90% on 2*14t/h plant.
  • Fluidized bed combustion optimization and CO reduction, High performance deNOx from SNCR installation, Zero liquid release, Semi dry or Wet FGT replaced by dry high performance VapoLAB™ process.
