摘要： A process is described, as well as a plant, for treating a raw vent gas (4,4′) containing bitumen vapours and released by a piece of equipment (1) of a polymer-bitumen membranes production line, in which operations are carried out involving a filler powder (3), such as an operation of mixing the filler powder (3) with the bitumen (2), during which the raw vent gas (4,4′) is changed from a substantially powder-free raw vent gas (4), into a raw vent gas (4′) containing the filler powder (3). The process includes steps of first conveying the raw vent gas (4,4) into a gas-washing device (20) along with a solution (9) of a surfactant; contacting the raw vent gas (4,4) with the solution (9) and removing the powder from the powder-containing gas (4′), releasing a purified vent gas (5) that is substantially free from the filler powder; conveying the purified vent gas (5) into a boiler (40) and burning the bitumen vapours. In a preferred exemplary embodiment, it is conveyed in the gas-washing device only the powder-containing gas (4′) produced during the operations of the piece of equipment (1) that involve the filler powder (3), while in the remainder steps the substantially powder-free raw vent gas (4) is directly conveyed into the boiler (40) by a direct vent line (50) that can be automatically selected. In a preferred exemplary embodiment, the gas-washing device comprises a tank (25) configured to form inside a predetermined head of the washing solution (9) and having an inlet port for the raw vent gas arranged below the liquid head. The process prevents the powder from quickly reaching the boiler (40) making the burner and the heat-exchange surfaces ineffective.

摘要： A passive and active sampler for airborne particulate sampling (especially particles of biological origin) and a method of using same are disclosed. The sampler includes a sampler base portion of variable size and shape having a longitudinal body and an inner surface. The sampler base portion is configured with a plurality of air channels having variable air channel spacing therethrough the longitudinal body. A plurality of layers of ferroelectric film have a first side and a second side polarized by application of an external electric field such that the first side produces a negative electric field at a first surface and the second side produces a positive electric field at a second surface. The plurality of layers of polarized, ferroelectric film are disposed thereon the longitudinal body with their opposite polarization directions facing each other across a fixed air gap to collect both charged and uncharged particles. The use of such technology as an electrostatic precipitator for active sampling of airborne particulates and a method of using same are further disclosed. This electrostatic precipitator technology can be used for bioaerosol or general particle filtration, as in HVAC systems.

摘要： A system for treating exhaust gas generated by combustion of biomass comprises a frame, a first cyclonic separation stage supported on the frame and comprising a plurality of parallel gas cyclones in fluidic communication with an inlet receiving the exhaust gas for removing from the exhaust gas particulate matter exceeding a first threshold size, and a second bag filtration stage supported on the frame and comprising a plurality of serially-communicated baghouses each comprising a plurality of bag filters therein for removing, from the partially treated exhaust gas received from the first cyclonic separation stage, particulate matter exceeding a second threshold size that is smaller than the first size which was passed through the first treatment stage. The gas cyclones of the first stage are arranged in a laterally extending row across the frame and the baghouses are arranged in a longitudinally extending row across the frame.
