Shell - Continuous Real-Time Economic Air Monitoring Systems (CREAMS)
Shell’s new Continuous Real-Time Economic Air Monitoring Systems (CREAMS) offers to calibrate a number of public-market ready, low-cost air quality sensors with existing data/methods from more established methods, and if needed provide one of these monitoring/modelling systems to use as a calibration standard. CREAMS have been extensively studied by the EPA and found to be useful for community concerns, especially before citizens post on social media or get news media involved. You can choose your sensor (e.g. on amazon.com) or we can help or select one for you or provide links to some reviews we’ve found useful. (Hope not too long – don’t have way/time to count characters.)
- Newly emerging air quality sensors continue to be used and evaluated by EPA and other governmental agencies.
- Facilities can benefit from these new sensors because they are:
- Low cost | Multiple sensors used at multiple locations compared to traditional ambient air monitoring equipment.
- Portable | Sensors are normally stand-alone and turn-key. Expensive temperature-controlled monitoring trailers are not required.
- User-friendly | Sensors require little maintenance compared to traditional ambient air monitors and are easy to install and operate.
- Remotely accessible | Data is cloud-mediated and can be reviewed remotely. Alarms may be used on some equipment when values exceed air quality thresholds.
- Some of the concerns of the new sensors are accuracy, interference with humidity/other pollutants, and repeatability. Because of these concerns, data are open-source and the end-user can do their own validation if required.
With CREAMS approach the traditional monitoring is used to form a benchmark of air quality with high accuracy and high repeatability at one or two locations. Collocated emerging sensor(s) are placed adjacent to the traditional monitoring trailer, so a site-specific reference standard can be supplied to the new sensors. Having established the data quality of the new sensor, additional new emerging sensors may be placed at multiple adjacent locations to improve the granularity of measurement and provide a bigger pollutant footprint in the area of interest.
In lieu of using traditional monitoring equipment/trailer, initially, the emerging sensors may be used as an indicator of pollution levels to determine if more refined ambient air monitoring should be considered. This equipment may be in used by environmental groups and interested general public individuals to assess how a neighboring plant is affecting their offsite community. Industrial representatives should be making their own assessment so they are not blind-sighted by data with questionable quality control/assurance from the general public.
Other uses of the emerging sensors are determining pollutant hotspots or for detecting equipment malfunctions/leaks within a facility.
Combining both monitoring technologies in CREAMS encourages a more robust, forward-thinking approach for collecting data over a larger area and at a more economical price. Please contact us if you would like to discuss improving your monitoring program using this or our other new technologies.
