摘要： A method and apparatus for micro-aeration of large scale fermentation systems is provided. The micro-aeration system includes a fermentation reactor, a sparging apparatus, and a micro-aeration gas mixture delivered to the fermentation reactor via the sparging apparatus. The micro-aeration gas mixture is a very low oxygen concentration mixture comprising an oxygen containing gas and an inert carrier gas that is preferably recycled through the fermentation reactor. The inert carrier gas is preferably nitrogen whereas the oxygen containing gas is oxygen or and is introduced to the fermentation reactor at a minimum superficial velocity of about 0.02 m/sec to produce a uniform dispersion of the oxygen/air throughout the fermentation broth while concurrently mixing the entire fermentation broth. The micro-aeration method and apparatus further comprises a controller operatively coupled to one or more control valves for regulating the micro-aeration conditions in the fermentation reactor.

摘要： An annular divided wall column for the cryogenic rectification of air or constituents of air is provided. The annular divided wall column includes a first annular column wall and a second annular column wall disposed within the first annular column wall to define an annulus column region and an interior core column region. The present annular divided wall column further includes structured packing elements disposed within at least the annulus column region as well as a ring-shaped cantilevered collector; and a ring-shaped distributor disposed in the annulus column region above or below the plurality of structured packing elements. The thermal expansion and contraction of the second annular column wall in a radial direction and in an axial direction is independent of the thermal expansion and contraction of the first annular column wall in the radial and axial directions.

摘要： The present invention provides a low cost surge tank design for pressure swing adsorption plants that does not contain internal structures, achieves good mixing and is 15-20% less expensive than the conventional designs. The surge tank is characterized by having a first inlet located in the upper quadrant of said surge tank and a second inlet located in the lower quadrant of said surge tank, wherein said inlets configured to fluidly couple the interior of said surge tank with the exterior of said surge tank; and wherein said first and second inlets are tangentially configured to allow flow to enter said surge tank in diametrically opposite directions.

摘要： The invention relates to a method and control system to control the speed of a centrifugal compressor operating within a vacuum pressure swing adsorption process to avoid an operation at which surge can occur and directly driven by an electric motor that is in turn controlled by a variable frequency drive. The claimed method determines the optimal speed for operation of the compressor along a peak efficiency operating line of a compressor map thereof. Speed of the compressor is adjusted by a feed back speed multiplier when the flow or other parameter referable to flow through the compressor is below a minimum and a feed forward multiplier during evacuation and evacuation with purge steps that multiplies the feed back multiplier to increase speed of the compressor and thereby avoid surge.

摘要： A cyclic adsorption process is provided having pressurization and depressurization steps and driven by one or more centrifugal machines operating under acceleration and deceleration conditions wherein the deceleration rate of the machine is controlled to minimize power consumption and maximize the efficiency of the process. The operating speed of the centrifugal machine during deceleration is matched to the measured pressure ratio conditions so that the centrifugal machine arrives at its minimum operating speed near the point required to begin acceleration.
