Continuous Emission Monitoring Systems

Overview
Continuous emission monitoring systems (CEMS) measure airflow, dust, the concentration of air pollutants (such as SO2, NOx, CO, etc.), and other parameters related to emissions. Required parameters depend on the type of stationary source and local regulations. A standard CEMS consists of a sample probe, filter, sample line (umbilical), gas conditioning system, calibration gas system, and a series of gas analyzers that reflect the parameters being monitored. Typically monitored emissions include: sulfur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen chloride, airborne particulate matter, mercury, volatile organic compounds, and oxygen. CEMS can also measure airflow, flue gas opacity, and moisture.

Case Studies.
Case Study
Worldwide IT Leader Manages Enterprise Energy and Sustainability
To understand their complex global energy consumption and emissions footprint, Cisco needed a software solution to help them manage disparate energy- and emissions-related data inputs across their enterprise, integrate and analyze their sustainability and energy metrics, embark upon energy and emissions mitigation projects, and report results publicly. Cisco also needed to perform detailed interval analysis of their high energy-usage facilities.
Case Study
GPC streamlines Clean Air Act Title V record keeping using Locus Platform
Grain Processing Corporation (GPC), a leading U.S. manufacturer of corn-based products, needed a smarter, more efficient tool to capture, track, notify, and report daily Clean Air Act Title V compliance parameters for numerous emission sources and points at their various production facilities. GPC was using SharePoint to enter over 20 daily logs at two facilities and had to address several questions per log and per shift, throughout a two-shift day. Their system had no reporting or notifications, and there was no consistency between the forms in the system. The EHS manager would spend weeks searching through information to obtain the data needed for GPC’s annual Title V certification report and other reporting needs.
