CEM - Abstract

Abstract Information :

Adoption of real-time monitoring in 2014 had set the first foot towards automated pollution monitoring and reporting in India. However, delayed by almost 5-6 decades compared to when the USA and EU adopted, the Indian market picked up fast. Under this, not only continuous emission monitor (CEM) but also effluent quality monitors (CEQM) are required to be installed. Beside this, installation of continuous AAQ monitors (CAAQM) had already been in practice. Although, the driving factor behind adoption of real time monitor was to initiate the practice of self-monitoring and reporting among the industries, one of the most immediate benefit expected was to improve data accuracy and credibility, over what was being missed in the convention periodical monitoring and reporting system. The conventional system allowed industry-hired laboratories to get monitoring done and giving a report to industry which used to get submitted to the environmental regulator. Such reports were often biased to show the compliance on paper but there was no way to cross-check and verify on regular basis. Real-time monitor gave the tool to the environmental regulators to keep round-o-clock vigil and carry data comparison, besides having benefit of immediate control and safety in abnormal conditions. Dealing with large industrial scale, variety of industries and data manipulation issues, India continuously worked on data acquisition and handling system, leading to many innovations which make it unique: • Direct data transfer: Unlike prevalent system in the USA, UK and EU, Indian system makes real-time data available directly from analyzer to the central regulator and respective state regulator in parallel through an IoT or data logger. Industry can access the data in parallel or through regulators server, but can’t put any intermediate device of PC. • Integrated and expandable: This data acquisition system integrates all the monitors- CEM, CEQM and CAAQM- installed in one industry through one specific TCP/IP to the regulatory server and is capable to expand for more installations. • Two data transfer: The data handling system is a two-way data transfer system. Where industry sends data from analyzer/monitors to the regulators, the regulatory sever can send alarms, notifications to the industry/client server for immediate action. • Remote check system: for gaseous CEM, Indian regulation mandates facility for remote check or calibration where regulator can directly give command to the industry analyzer for zero and span drift check remotely and evaluate the analyzer response and accuracy. • Encrypted, secure, wide access and storage- Indian data handling system allows data transfer in the encrypted form, securely to the server and access to the authorized person from anywhere and anytime and with huge storage capacity.
