Abstract:
A method for ultra-high particulate collection of sub-micron aerosols in a fuel gas, comprising:providing a fuel gas under pressures exceeding 10 bar, the fuel gas also having an initial particulate loading between 8 grains/ft.sup.3 and about 800 grains/ft.sup.3 ;conveying the fuel gas to a first venturi scrubber for removing a relatively large particulate load in the fuel gas and leaving smaller particulate load in the fuel gas which is not removed in the first venturi scrubber;conveying the fuel gas with the small particulate load to an electrostatic agglomerator for agglomerating smaller particles into larger particles; andconveying the gas with larger particles to a second venturi scrubber for removing the larger particles.
