Abstract: A particulate control system which includes a collector such as an electrostatic precipitator (ESP) is improved by incorporation of a collector, such as an electrostatically enhanced separator (EES) connected parallel with the collector and wherein the output flow from the collector is split and a portion of the output flow from the collector is directed through the separator. The input flow to the collector may also be split so that a portion is directed to the separator as well as the collector. A bleed line may also be employed to connect the separator to the collector resulting in a bleed flow from the separator to the collector.

Abstract: An improved combined power generation cycle has been provided for electric power generation from gasified solid fuel such as coal or biomass. The power cycle provided by the present invention does not require the use of high-temperature particulate control systems or wet clean-up systems. A high-temperature high-pressure gas stream is first cooled in a heat-transfer system and then cooled again by any one of a variety of methods before the particulate solids and hazardous air pollutants are removed in a low-temperature dry solids collector. Then, the clean gas is reheated in the same heat-transfer system and is ready for use in power generation. Net plant efficiencies can be improved by injecting water or steam upstream of the topping cycle power generating means.

Abstract: A method and apparatus for carrying out electrophoretic separation is provided which imparts a fractal field component to the particles themselves or to the medium in which the particles are to be separated which, in combination with a steady field component, provides for a fast electrophoretic separation method that can be used on molecules and particles of a larger size than currently available electrophoretic methods.

Abstract: The present invention relates to an improved design for a moving liquid membrane module. In one embodiment, the tubular or hollow fiber module, at least one tubular or hollow fiber element is contained within a housing. This element comprises an inner tubular membrane and an outer tubular membrane. The element comprises a first tubular membrane located within a second tubular membrane of larger diameter. The membrane liquid is continuously passed through annular gap between the two tubular membranes. The feed fluid is continuously passed through the lumen of the inner tubular membrane and the purge or strip fluid is continuously passed over the outer surface of the outer tubular membrane. In a second embodiment, the spiral wound moving liquid membrane module, a spiral wound cartridge is incorporated into a housing. The cartridge is formed by wrapping at least one permeant depletion channel, one permeant enrichment channel and one membrane liquid channel around a core tube.
