Process analysers and CEMS

We turn the sample into reliable data: design, engineering and integration of process analysis systems and CEMS.

Process analysers and CEMS

We design and integrate analysis systems tailored to each plant and process, from chromatography to multi-parameter measurement in critical environments.

We specialise in process analysers and CEMS (Continuous Emissions Monitoring Systems) for highly demanding plants, especially in petrochemicals, energy and chemicals. We have an engineering department specialising in process analysis that supports each system from the study of the sample to commissioning.

How we work

  • Technical study of the sample and the components to be measured
  • Selection of the most suitable equipment (chromatographs, photometers, sensors, multi-parameter analysers…)
  • Design of the analysis system and sample conditioning
  • Calculation of flows, transport lines, materials and response times
  • Detailed engineering to ATEX and customer requirements
  • Integration of SAMs, analysers, lines, cabinets and racks
  • FAT: leak, functional, electrical and control tests
  • Installation or supervision on site, commissioning and validation
Analyser rack integrated by MIESA

SAD: our own data acquisition system

Our SAD software (Spanish acronym for data acquisition system) is designed for data acquisition, recording and traceability in CEMS: full integration with the emissions analysers, regulatory compliance, automatic reports and real-time data. It can also be integrated with artificial intelligence models to analyse trends, anticipate deviations and optimise the process.
