Petroleum Refineries

We understand continuous monitoring requirements and we understand how refineries are unique.

Environmental Systems Corporation has been in Air Regulation Compliance for nearly 50 years. Our CEMS Data Acquisition System (DAS) is installed in facilities across many industries, including refineries, with 3000+ sources successfully reporting under NSPS, MACT and more. Let our experience assist you in complying with new requirements for continuous monitoring for air compliance.


How ESC Can Help

Our DAS ensures data validity and simplifies recordkeeping, QA and reporting. If any of the following sounds familiar to you, we may be able to help.

  • You have legal requirements which you must meet to demonstrate air regulatory compliance, requirements that could engender substantial fines if they are not met, or allow environmental hazards to proliferate. But you don't have the tools you need to do your job effectively.
  • The public eye is upon your company, expecting pollution reduction and immediate knowledge of excess emissions. Corporate wants hard numbers that they can count on and communicate.
  • The number of locations that you are required to monitor may have quadrupled in the last few years, and the number is likely to increase with each new turnaround as sources are modified.
  • The new collection device analyzers all have calibrations, quarterly testing and quality control activities associated, in addition to gathering the monitoring data.
  • Some of the requirements that you must meet are operational adjustments that should be made based on the current state of the system, right now. But Environmental is often hamstrung on this, either because calculations are happening well after the fact or because you lack access to the DCS.

"If you keep up with things all it takes is a few minutes a day of quick checks and coding, then end of quarter reporting is easy." Jeremy Meeks, Environmental Engineer, CHS Refinery at McPherson

The Distributed Control System (DCS)* with its historian, was designed for process control, not for monitoring and reporting emissions. Yet, because of its capabilities and availability it has been relied upon for most monitoring needs in refineries. There are a lot of parallels between a DCS and a Data Acquisition and Handling System (DAS or DAHS). So much so, that getting by with the DCS has mostly worked until recently. The majority of environmental folks using this solution have supplemented with Excel spreadsheets to apply the required compliance calculations and do the averaging and reporting, so there has been a fair amount of manual work involved, but it was mostly manageable in the past.

Now, starting with the Petroleum Refining Initiative and moving on through Subpart Ja, the Refinery MACT rules, the Residual Risk and Technology Review and more coming with the National Uniform Emissions Standards, plus EPCRA, whatever your state has laid upon you, mandated electronic reporting and... The refinery industry has been targeted so hard by air compliance regulations that the work may not be manageable any more.

In fact we have seen a noticeable upswing in the number of refineries coming to us in search of a solution to their recordkeeping, QA and reporting workload.
