Your team stays in control, with confidence in the data behind every report. QA and Certification, Simplified StackVision supports the full cycle of QA and certification testing from running linearity checks and relative accuracy test audits to generating the reports regulators expect to see. Create test records and analyze results in real-time while testing is underway, reducing turnaround time and the risk of documentation gaps. Regulatory Reporting Use StackVision to quickly compile and deliver accurate CEMS, CPMS, and COMS reports to the relevant state and federal agencies without worrying about human error or outdated calculations.

The Alliance way is a true differentiator, providing solutions-based onsite testing and monitoring with top SMEs to handle immediate environmental challenges. Alliance is positioned as your partner of choice for highest-level delivery.” Martin Gibson Executive Vice President, Emissions Monitoring StackVision in the Field: Petrochemical Refinery A leading integrated downstream energy company was operating four refinery flare gas chromatographs with significant monitoring gaps. The Challenge: Their challenges were operational and financial: Pass/fail calibration emails were manual, time-consuming, and easy to misread DCS alarms in the central control room were frequently missed No remote visibility or control of analyzer operations — technicians had to be on-site for routine tasks The Results: After implementing StackVision, the refinery gained direct, automated data feeds from analyzers — including daily calibration reports, weekly trend data, and immediate pass/fail notifications via text alerts. Remote access allowed calibrations and cylinder gas audits to be performed without dispatching a technician. 50% Reduction in GC Emergency Work Orders 500+ PM man hours saved per year 48% Reduction in CEMS downtime vs prior year 83% Reduction in unscheduled downtime Total cost savings exceeded $278,000 Schedule a Live Demo Back to All Services Learn more about StackVision.
