Abstract:
A process for purifying a gas which comprises the steps of:feeding the gas through at least one venturi cell at a pressure and a flow rate, said cell including:an inlet in a housing;an outlet from said housing;an inner lower conical segment within said housing, said inner lower conical segment having an open base through which said gas can enter;an outer lower conical segment within said housing, said outer lower conical segment surrounding said inner lower conical segment, said outer lower conical segment having a closed top, an open base through which said gas can exit, and an aperture through which at least a portion of said inlet communicates and whereby a chamber is formed between said inner and outer lower conical segments;an inner upper conical segment within said housing and connectedly affix to said inner lower conical segment in a leak-proof manner and in communication with said inner lower conical segment to permit gas flow therethrough;an outer upper conical segment within said housing, said outer upper conical segment surrounding said inner upper conical segment, and in communication with said inner upper conical segment, said outer upper conical segment further in communication with said outlet, and whereby an upper chamber being defined between said inner and outer upper conical segments; anda pressure differential creating means for creating a pressure differential between inner lower conical segment and said inner upper conical segment.
