Itech - Version VisualCEMS -Continuous Emission Monitoring Data Management System

Control Systems

• Combustion Processes
• Steel Ovens
• Turbogenerator monitoring
• Gas compressor stations
• Measurement of VOCs
• Incineration
• Biofermentation
• Monitoring air
• Granary monitoring
• Remains of O2 and measurement of gas purity

Calculations

• Emission Limit Value readings, daily, every hour, every half hour, 10 minutes, etc.
• Control of unavailability
• Abnormal operating conditions
• Totalers

Generation of documentation for the environmental department

• Data processing according to European technical instructions (UNE-EN 14181, EN 13284-2), US EPA and regional standards.

Alarms

• By content, time and amount
• Due to errors
• Breach of the Emission Limit Value
• Incorrect media
• Peripheral fault

To treat emissions in a way so that we can control parameters such as:

• Measured value
• Calibrated value
• Standardised value
  • To define measuring conditions which determine the peripherals
• Validated value
  • To define validation calculations
  • Confidence interval
• Validated semi-hourly average value
  • To define the amount of data needed to calculate the average hourly value
• % of validated semi-hourly average values which exceed the ELV
• Number of validated semi-hourly average values which exceed the ELV
• Validated hourly average value
  • To define hourly and semi-hourly data which can be lost while the day is still considered valid
  • To define the maximum number of non-valid days per year
• % of daily average CO values which exceed the ELV (50 mg/Nm3)

• % of ten-minute average values which exceed the ELV (100 mg/Nm3)
• Number of ten-minute average values which exceed the ELV (150 mg/Nm3)
• Average value (period between ½ hour and 8 hours) of Hg
• Hourly periods of abnormal operation
  • To define abnormal operation
• Start-up periods and shutdown periods
  • To define the conditions that characterise start-up or shutdown
• Flow diagram for each system tag in order to perform the required operations at all times, thus responding to any regulation that may arise
• Follow-up and compliance reports in accordance with EPA laws, UNE-14181, Royal Decrees, Decrees, Technical Instructions (TI) and Integrated Environmental Authorisations
• Sending files to the Council
• Systems redundancy
