Industries across the globe need to check on their emission gases so that they can control the impact of these gases on the environment. Emphor IAD has a wide range of CEMS that fits for different industries. This article looks into various CEMS and rising concerns regarding its implementation.
The industrialization has caused severe damage to our environment. Toxic emission from various industries pollutes the air, water and land. Power plants and many major industries are emitting a huge amount of toxic gases into the air. Recognizing the current environmental conditions, governments across the globe are taking major steps in curbing emission of toxic gases.
With rising environmental concerns across the globe, it has become manufacturing companies to keep a check on pollutant emission rates. This is done by continuous emission monitoring systems, CEMS as shorthand. CEMS is the conventional method used for continuous monitoring systems which are approved by authorities. Few countries permit the use of predictive emission monitoring systems for a certain application. The scope of emission monitoring system can’t be explained without the knowledge of continuous emission method and predictive emission monitoring systems.
Emission Monitoring System Types
CEMS consists of a system that determines gas or chemical compositions according to specific pollutants. Analyzer measurements and software produce results of the applicable emission limitation or standard in units. CEMS are mainly classified according to their mounting style, either extractive or in-situ. In extractive systems, probe and analyzer systems are two different systems which help in checking gas before they are passed on to analyzer. At analyzer, gas components are determined. In in-situ, the analyzer is made to come in direct contact with the emission gases eliminating the need of sample testing.
In PEMS, the software is used to check gas concentration or emission rate based on various parameters that predict the emission levels. A PEMS include sensor validation system to ensure accuracy in predicted emission data. The system can be used independently for qualified emission sources as a convenient option for CEMS. PEMS doesn’t work on default mode which essentially needs to be trained to create appropriate emission models. CEMS are therefore used to measure actual emissions as a substitute. The various outputs are collected from various sources to correlate input and output values. Once the emission type is determined, the system performs various tests to validate the model for operating conditions. After the results are validated, CEM can be replaced by PEM for emission data. The PEM system predicts the emission level based on process data and emission modelling.

Issues concerning Emission Monitoring System
The current emission monitoring system is facing issues, which need to be addressed for better control of toxic gases and to secure the environment. The manufacturing industry is very conservative and is too slow in adopting new technologies. Introducing new technology involves upscaling the workforce, work process, standardization and establishing best practices. Adopting new technology without clear prospects can bring damage to the establishment. Technological invasion in the sector is slow due to the strict regulatory controls. Regulatory authorities require multiple approvals involving independent assessments of the new technology to work seamlessly in the future.
Authorities are not taking enough effort in acquiring equipment in few developing countries. Although such countries have experienced robust growth, regulatory authorities have been struggling to enforce environmental laws successfully. Without strict environmental laws, we have observed that many industries lack robust emission monitoring systems. Industry managements find it easy to get out of law violating monitoring laws. These practices severely limit the growth prospects of EMS.
