    摘要: An apparatus is disclosed for generating a multiple phase dispersion and distributing said multiple phase dispersion as globules in a suspension phase. The apparatus comprises a conduit for introducing a first fluid under pressure into a first zone including a porous fluid dispersing layer. This first zone is in fluid communication with a second zone through the porous fluid dispersing layer. The second zone has introduced into it a second fluid under pressure through inlets. The first fluid is dispersed as bubble-like micro droplets in the second fluid by passage from the first zone through the fluid dispersing layer into the fluid in the second zone. An outlet zone is in contact with the second zone and comprises a perforated nonporous layer having an outer and inner surface and includes a porous flow distribution layer substantially in contact with the inner second zone facing surface of the nonporous layer. The multiple phase dispersion formed in the second zone enters the outlet zone through the porous flow distribution layer and exits the outlet zone as globules of predetermined size through the perforations where the outer surface of said perforated nonporous layer forms an interface with a suspension phase which is immiscible with the second fluid.The instant invention further relates to a process for generating multiple phase dispersions as globules in a suspension phase.

    摘要: A hollow fiber contactor and process for fluid treatment having forced circulation with entry of fluid to be treated through the open ended lumen of a porous input hollow fiber having its opposite end closed and exit of treated fluid through the open ended lumen of an adjacent or nearby porous output hollow fiber having its opposite end closed. Fluid to be treated passes through the porous wall of an input hollow fiber, passes in contact with a treatment medium between the input and output hollow fibers forming treated fluid which passes through the porous wall of an output hollow fiber and exits the process. This invention provides high contact with treatment medium between the hollow fibers, especially suitable for selective sorption for gas purification or separation and for conduct of catalytic reactions.

    摘要: A separation process is described for separating a known material from a mixture of materials (which may contain unknown materials) using displacement chromatography. The process comprises passing a mixture of materials, including a known material to be recovered, dissolved in a liquid carrier, if necessary, through a first packed column and into a second packed column until all of the known material has passed through the first column and has been loaded onto the stationary phase packing in the second column. A displacement agent, capable of being more strongly bound on the stationary phase packing in the second column than the known material, is then passed through the second column to displace from that column all of the materials in the mixture less strongly bound than the known material, and then to displace the known material from the second column. The columns are then regenerated, preferably by passing a carrier directly through column 2 (in the forward direction of flow) and then passing the effluent from column 2 through column 1 in a reverse direction. The flow through column 2 is continued until all of the displacement agent has been removed from column 2. In one embodiment, a solvent is also counter flushed through the first column to dissolve any precipitates therein.

    摘要: A cyclic adsorption process is provided in which two zones are employed--an adsorption zone and a heat storage zone. A fluid stream containing a solute to be removed therefrom is passed through the adsorption zone and the effluent is then passed through heat storage zone. The conditions under which the stream is passed through the adsorption zone are selected so that the rate of progression of the heat transfer front and mass transfer front are substantially equal. This results in an optimum temperature of the effluent stream for efficient heat recovery in the heat storage zone. During regeneration of the adsorbent, a fluid regenerating stream is passed through the heat storage zone where it is partially heated. At a point between the adsorption zone and the heat storage zone the regenerating fluid stream is further heated, via an additional heat source, and passed through the adsorbent zone. The amount of additional heat is sufficient to effectively desorb the adsorbent. Alternatively, of course, a pressure reduction and a combination of heat addition and pressure reduction may be employed to desorb the adsorbent.
