ENV-04-177 Advantages of a Real-Time Emissions Data Management System for NOx Reduction Record Keeping and Reporting

Description:

Lyondell-Citgo Refining, LP (LCR), a 270,000 bbl/day refinery located in the Houston/Galveston Area, has successfully implemented a real-time process historian based system for meeting the monitoring, record keeping, and reporting requirements under the Texas Commission on Environmental Quality’s (TCEQ’s) NOx Reduction rules. This paper presents the challenges that LCR faced in meeting the NOx reduction rules requirements; the reasons that LCR selected a real-time process historian-based emissions data management solution, and the benefits that LCR has been able to realize. Even though this paper focuses on NOx, LCR selected a system that was fully capable of handling the requirements for any other regulated pollutants (e.g. CO, SO2, VOC, etc.) of which E!CEMS is capable. LCR’s goal was to implement a fully integrated Continuous Emissions Monitoring System (CEMS) Data Historian and Reporting system for NOx reduction record keeping and reporting. LCR’s ideal solution was one that met the mandated environmental regulations but also offered value and was an off-the-shelf standard software product.
