Abstract: A thin-walled deep grain storage tank with improved sidewall discharge system involving a plurality of successive flat plates periodically mounted to the inside of a pair of vertical, parallel I-beam and/or Z-bar sidewall support members with openings for grain flow between successive plates, and a sidewall discharge means at the base of the tank. In this manner an internal chute is formed capable of staged discharge from successive top strata of stored grain. Such a system is useful in alleviating the problems associated with the build up of excess eccentric sidewall pressure during grain discharge without significantly altering the design and construction parameters and their associated economics.

Abstract: An apparatus for separating liquid and associated liquid vapor from a gas stream by contacting liquid brine in concurrent flow through and across a plurality of stages and direct contact with a bed of calcium chloride within an upper portion of the apparatus to remove a final portion of liquid from the gas stream. The improvement being in the tapered bed of desiccant material and the stage configuration. Each of the stages has an upper tray and a lower tray connected thereto with a central conduit connected to the upper tray enabling liquid brine to traverse from the upper to the lower tray. A plurality of mixing housings extend from above the liquid level in the lower tray to slightly above the upper tray and each has a base housing coaxial therewith and of a larger diameter which extends from the lower tray to slightly below a lower end of the corresponding mixing housing.

Abstract: Method and apparatus for purifying or reclaiming liquid desiccant comprising heating a water rich desiccant to form dilute desiccant vapor; partially condensing said vapor to produce a purified desiccant equal in strength to the feed stream, reintroducing a first stream of said vapor by sparging into the means of heating said desiccant and cooling a second stream of said vapor thereby refluxing condensible desiccant and venting non-condensible gases, and recovering condensed vapor for use elsewhere.

Abstract: A system for regeneration of a liquid disiccant which utilizes a reboiler and still column to remove a major portion of absorbed water and then exposes the hot, partially dehydrated desiccant to a flow of dry, inert flue gas and a partial vacuum, in order to remove additional water from the desiccant.

Abstract: A gas-liquid separator of the centrifugal type wherein the mixture is first introduced into a top chamber of a vertical vessel where it is given a spinning motion forming a vortex with liquid initially separated and drained to an intermediate chamber and then to a lower chamber for removal. The remaining gas-liquid enters a centrally located vortex tube where additional entrained liquid is skimmed off at a slot open to the intermediate chamber. Additional separation occurs as the gas and remaining liquid entrained therein strikes a conical surface and other diversion baffles.
