Abstract:
Refinery labs face increasing high throughput demands despite challenging sample matrices and limited operator availability. Petrochemical wastewater and brines are monitored for Total Organic Carbon (TOC) to ensure compliance with environmental regulations and to protect downstream reuse or disposal pathways.
High salinity and particulates in these samples can disrupt TOC analysis and increase maintenance demands. This presentation outlines strategies for optimizing TOC workflows using two high-temperature combustion systems with NDIR detectors. Designed for demanding petrochemical applications, the multi N/C 3300 features a salt kit that prevents corrosion and extends maintenance intervals, while the multi N/C 2300 specializes in the direct injection of particle-rich samples. The reverse rinse function and Self Check System work together to flush residues and proactively monitor system health, ensuring consistent performance with minimal operator intervention.
The talk will include case studies from Gulf Coast refineries, highlighting practical approaches and instrument configurations that have successfully supported TOC analysis under challenging conditions.
