Do You Require a Continuous Emissions Monitoring System (CEMS)?

Majority of carbon adsorption systems are equipped with a monitoring system that determines the carbon bed breakthrough or saturation of beds. They also help maintain environmental compliance by limiting emissions to the atmosphere.

At Process Engineering Services, we have our own model of monitoring system (105 FID CEMS) that is fully manufactured by us. A dozen of these systems are in operation, some even for more than 20 years. Click here to download the general parameters document.

Full Specifications of Model No. 105 Monitoring System

  • This fully pre-engineered, modular-designed and free-standing equipment is equipped with a Hydrocarbon analyzer, a recorder and a calibration facility:
    • Rosemount 400A Total Hydrocarbon Analyzer (has 7 selectable ranges from 0-1 PPM to 0-30,000 PPM full scale, with valving for manual inlet sampling for on-demand real-time measurement of adsorber efficiency)
    • Flame Ionization Detector / Analyzer (to determine the total gaseous organic concentration, in compliance with the EPA method 25A as stated in the federal regulations)
    • Honeywell DR 4300 Single Pen Circular Chart Recorder (with internal relays for on / off control and alarms, internal sample pump and calibration facilities)
  • It includes the following:
    • All calibration valving and tubing
    • All interconnected tubing and wiring between the absorber and monitoring system
    • Compressed gas bottle stand with chains
    • Cabinet with rack-mounted monitor, recorder and all valving mounted in it
    • All electrical / mechanical switch-over controls required to install the monitoring system to adsorption system (solenoid sampling valves, filters, timers, etc.)
    • 25-day supply of chart papers and pens for the recorder
  • Compressed gases required (our price doesn't include regulators and gases):
    • Hydrogen / Nitrogen mix (fuel)
    • Methane in air (calibration gas)
    • Breathing quality air (combustion air) < 1 PPM THC
