Continuous emission monitoring system (CEMS)

Home » Services » Continuous emission monitoring system (CEMS)

Integrated CEMS project Management

At Envira we supply complete CEMS monitoring system, performing turnkey projects and providing our customers with a multidisciplinary technical team that facilitates the comissioning of the system, avoiding production interruptions.

Study & Diagnosis

Solutions for every industry

We are aware that every industry is different. That is why we study in depth the sources of pollutant emissions and key requirements in each industry to carry out a diagnostic study that allows us to design an accurate and reliable continuous emissions monitoring system that allows us to optimise processes while complying with current regulations.

Therefore, we are able to obtain the maximum balance between production and emissions.

Our experience is proven in the following industries:

Automotive industry, power plants, chemical industry, cement industry, paper industry, metallurgical plants, petrochemical industry, pharmaceutical industry, waste treatment plants, food and beverage industry.

Design & Commissioning

We design the CEMS in our own facilities by using internationally recognised brands with type-accredited instrumentation to meet the most rigorous international approvals and standards.

Data Acquisition

Acquisition & Control System

We are committed to a different approach using state-of-the-art PLCs as the CEMS acquisition and control platform, offering significant advantages in industrial automation and guaranteeing a minimum 98% data availability.

In this way we offer a system with flexibility in programming languages, easily integrated with the cloud and IoT technologies and also allows the use of standardised industrial protocols:

· Ethernet
· Profibus
· Profinet
· Modbus + TCP/IP

Comprehensive CEMS Maintenance Plans

Our specialised technical service offers customised maintenance, verification and calibration plans for monitoring equipment based on Directive 2008/50/EC.

This service consists of predictive, preventive and corrective maintenance for gas and particulate analyzers of automatic measurement systems.

These plans include periodic calibrations and zero and span checks traceable to national and international reference standards, checking of operating parameters and replacement of fungibles so that the instrument operates according to the specific requirements of the QAL 1 certification.

We can guarantee high availability and agility of response to incidents or breakdowns. We also have all the necessary means for on-site adjustment, repair and calibration, as well as backup instrumentation for the replacement of equipment, facilitating maximum operability.

High availability
We have expert technicians distributed throughout Spain to respond as quickly as possible.
Precision and reliability
We perform periodic calibrations and zero and span verifications to ensure accurate and reliable data.
Continuous development
We have a team of engineers that allows us to offer an in-house electronic design and development service.
ENAC-accredited laboratory
At ENVIRA we have both in-house and mobile laboratory that allows us to carry out permanent and in-situ calibrations accredited by ENAC.
Official technical service
Our electronics and pneumatics workshop is endorsed by the brands we distribute, making us their official technical service.
Instrument replacement guaranteed
Redundant back-up instrumentation is always available at our sites to ensure equipment replacement in case of need.

NGC3 / QAL3 maintenance

In order to ensure the quality of data obtained by measurement systems in companies operating under EN 14181 standard, it is necessary to maintain strict quality control and quality assurance procedures, including maintenance, verification and calibration of measurement equipment.

In order to facilitate this task, ENVIRA has developed a specific computer application that allows an agile management of the maintenance and storage of the information corresponding to Quality Assurance Level 3.
