Leak Detection and Repair - United States Environmental ...

A typical reinery or chemical plant can emit 600­ 700 tons per year of VOCs from leaking equipment, such as valves, connectors, pumps, sampling con­ nections, compressors, pressure-relief devices, and open-ended lines. Table 3.1 shows the primary sources of emissions from components subject to equipment leak regu­ lations.


Theories and Applications of CFD–DEM Coupling …

Bio-particulate matter includes grains, cereal crops, and biomass that are considered discrete materials with irregular size and shape. Although the flow of these particles can behave like a continuum fluid at times, their discontinuous behavior cannot be simulated with traditional continuum-based modeling.

Carbon-based electrocatalysts for sustainable energy ...

Fuel cells are electrochemical energy devices that directly convert chemical energy into electric power without combustion, where the fuels (e.g. H 2) are oxidized in the anode to generate electrons and H + or H 2 O in acidic and alkaline electrolytes, respectively, as shown in Fig. 1(a). Then the electrons flow to the cathode reducing O 2 into H 2 O or OH −.
