Confidently Reduce VOC Emissions at the Fenceline to Meet Compliance

Jul 17 2018 Read 635 Times

The need to monitor the emissions of volatile organic compounds (VOCs) at the fenceline is increasing, particularly in the US and Canada. Last year, the environmental protection agency (EPA) updated method 325, a federal regulation known as 40 CFR Parts 60 and 63. That means that today oil refineries in North America are required to monitor volatile organic compounds, or VOCs, at the fenceline of their facilities, with monitors spaced at certain intervals depending upon the size of the refineries. The objective is to measure the emission of benzene to determine if there is a release of VOCs. Part “A” of the Method describes the field placement of the monitors, the passive adsorbent tubes that will collect the ambient air samples, and their sheltering requirements. It also details the 14-day sampling cycle along with specifics on tube cleaning and reconditioning. Part “B” describes how the samples will be analysed in a lab using thermal desorption-gas chromatography. The EPA is targeting benzene as the representative com­pound to evaluate the overall possible emissions of VOCs from refineries. Benzene is an inherent compound in crude oil. Crude oil is refined to make many products, including gasoline.

The regulation calls for the placement of up to 24 sampling stations along the fenceline of refineries. The sampling stations, or shelters, contain passive sampling tubes packed with an adsorbent to trap ambient air samples. The samples undergo testing every two weeks using Automated Thermal Desorption-Gas Chromatography/Mass Spectrometry (ATD-GC/MS) technology. Other detectors may be used, however, not recommended.  MS technology is used to ensure false positives are not reported.

From field sampling to data management, PerkinElmer has exactly what oil refineries need for Method 325 compliance. The EPA actually used the PerkinElmer® TurboMatrix™ automated thermal desorber (ATD) to develop this method. This solution includes sample shelters, passive sorbent tubes, the combination of PerkinElmer’s TurboMatrix™ ATD and Clarus® SQ 8 GC/MS, plus installation, system training, and world-class support and services.

Many refineries already have the capability to conduct their own VOC sampling, but this type of testing is new for them, and we have the experience to help. Therefore, most refineries are seeking help in both the sampling and analysis areas, so PerkinElmer is perfectly positioned to collaborate with these facilities to deliver cost-effective, complete solutions.
