Continuous Emissions Monitoring Systems (CEMS)

   Continuous emission monitoring system (CEMS) is the total equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyzer measurements and a conversion equation, graph, or computer program to produce results in units of the applicable emission  and transmit the information to the competent 

we provide CEMS system to monitoring : SO2/NOX/CO/CO2/HCL/HF/ dust/flue gas flow rate/pressure/temperature .more information pls visit www.gasese.com

Ammonia Slip Analyzer

Ammonia Slip Analyzer

SCR’S and SNCR’s reduce NOX emission by injecting ammonia into the combustion flue gas ,which ideally reacts with the NOX to form H2O and N2.The efficiency of the SCR/SNCR is determined by monitoring the outlet for excess NH3,referred to as NH3 slip .

The SNCR process requires the introduction and mix of Ammonnia or urea with flue gases in a hotter environment with a temperature optimized to between 800-900℃,Temperature control is important in the process,as low temperatures can cause a surplus of unreacted NH3

Extractive surrogate measurements will continue to dominate the utility market for now because of the ease of acceptability as part of a CEMS.Tunable Diode laser technology is proving to be the most accurate method.
