Thanks to a measurement campaign conducted along the perimeter of the plant, the SCAN360 \u2013 QUICK SCAN<\/strong> technology for calculating CH\u2084 emissions is a method capable of determining the concentrations of the emission plume downwind.
The results obtained by SCAN 360 SMART INSPECTION<\/strong> are combined with meteorological data and site geometry information to estimate gas emissions through inverse dispersion modeling<\/strong>.<\/p>\n

The inverse dispersion is carried out using a Lagrangian dispersion model<\/strong> called MICRO-SWIFT-SPRAY<\/strong>, developed by SUEZ AIR&CLIMATE<\/strong>, which can estimate CH\u2084 emissions for the entire site, as well as provide a list of the main sources along with their respective contributions to total emissions.<\/p>\n

 <\/p>\n

The two technologies are complementary: SCAN360 Quick-Scan<\/strong> enables a global assessment of emissions and their contribution<\/strong> using inverse modeling, while SCAN 360 Smart Inspection<\/strong> (based on the use of highly accurate infrared sensors like LGR\/Li-COR<\/strong> and advanced numerical dispersion models) identifies and precisely quantifies major emission leaks<\/strong>, offering essential information for mitigation.<\/p>\n

This method was initially developed for non-hazardous waste storage facilities<\/strong> under the European project WasteMiti2<\/strong>, funded by the European Union\u2019s main initiative created by the European Institute of Innovation and Technology (EIT)<\/strong> to address climate change through systemic innovation (EIT Climate-KIC<\/strong>). The project developed and validated the method for non-hazardous waste treatment facilities and later for wastewater treatment plants<\/strong>. The method was also evaluated and labeled<\/strong> by the Solar Impulse Foundation<\/strong> under the name “Rapid Scanning Service.”<\/strong><\/p>\n

Indeed, the primary goal of the SCAN360 QUICK-SCAN<\/strong> method is to rapidly “scan” the site\u2019s emissions to quantify them and identify major sources<\/strong>.<\/p>\n

The concentration mapping<\/strong> is initially established by dynamically measuring CH\u2084 concentrations in ambient air using high-precision, high-frequency spectrometers<\/strong> (LGR\/Li-COR sensors). Following the measurements, the emission sources and their respective emission flows can be determined through inverse modeling<\/strong>.<\/p>\n

The steps for applying this technology (as applied to specific case studies) are as follows:<\/p>\n

After a planning phase<\/p>\n

\u00a0involving site visits and recording CH\u2084 concentrations, meteorological conditions, etc., on-site monitoring<\/strong> of CH\u2084 emissions is conducted at the Valdeming\u00f3mez (Parque Foresta<\/strong><\/p>\n
