CEMS Analyzers Maintenance from ABB

Introduction

This course is designed to provide participants with a detailed and up-to-date overview of CEMS Analyzers Maintenance. It covers the purpose and objectives of CEMS, regulatory standards, emission parameters and extractive versus in-situ systems; the ABB CEMS system architecture, types of ABB analyzers and regulatory compliance and QA/QC requirements; the functional blocks and signal paths, sensor modules and measurement principles; the user interface and menu navigation, communication protocols and data access; working with flammable/toxic gases and electrical safety practices; and the analyzer cabinet ventilation and purging and lockout/tagout procedures. Further, the course will also discuss the NDIR measurement technology, zirconia oxygen measurement, paramagnetic oxygen measurement and FID and CLD technology (hydrocarbon and NOx); configuring CEMS system using ABB Panel 800 HMI, fieldbus/protocol settings (MODBUS, PROFIBUS), alarm and status configurations and data logger and historian configuration; the sample conditioning system (SCS), routine maintenance tasks, preventive maintenance scheduling and calibration procedures; and troubleshooting common issues covering signal loss and noisy readings, sensor contamination and blockages, flow and pressure anomalies and internal diagnostics and log review. During this interactive course, participants will learn the maintenance tools and accessories comprising of special ABB calibration tools, gas regulators, fittings, and tubing, diagnostic software tools and portable gas detectors and meters; the analyzer module replacement procedures, advanced diagnostic features and integrating with DCS/SCADA; the data logging and archiving, signal conditioning and analog output testing and redundancy and fail-safe operation; reading and interpreting ABB manuals and using wiring and layout diagrams; and applying maintenance SOP documentation and troubleshooting flowcharts.
