Abstract: An improved tower saddle packing having a general shape that is a segment of a hollow torus. The circumferential outer edges of the saddle define a plurality of radially, outwardly extending convex lobes. The lobes and wing portions preferably have weep holes to effectual wetting of all surfaces of the saddle. The hub of the saddle has in one aspect a plurality of apertures extending substantially across the hub. The saddle provides improved gas-liquid interaction, permits enhanced gas throughput in an absorption tower and allows for reduced tower packing sections.

Abstract: Apparatus and process for the production of gaseous sulphur dioxide mixture for conversion to sulphur trioxide in a catalytic converter in the production of sulphuric acid by the contact process. Apparatus comprises the furnace to produce sulphur dioxide gas from elemental sulphur and a first dry air stream; means for feeding a first portion of the sulphur dioxide gas to a waste heat boiler to cool the gas; the improvement comprising combining a second portion of the sulphur dioxide gas exiting the furnace with a second dry air stream to provide a combined gaseous stream which bypasses the boiler and subsequently is combined with the cooled sulphur dioxide stream.

Abstract: In conventional processes for manufacturing phosphoric acid, sulphuric acid is reacted with phosphate rock to produce weak phosphoric acid which is concentrated using steam from the associated sulphuric acid manufacturing operation. Low grade heat from the absorbers and drier of the sulphuric acid manufacturing plant has been wasted. According to the invention waste heat from the drier and one or more absorbers of the sulphuric acid manufacturing plant is used in all the evaporators of the phosphoric acid plant. The evaporators all operate at low pressures and their heaters are arranged in series, to enable the heat to be used at the relatively low temperatures available. The valuable steam is thus freed for other uses.

Abstract: A heat exchanger having a disc and doughnut baffle configuration, in which the tubes are laid out in a set of concentric rings. Each ring of a set contains the same number of tubes as each other ring of the set, and the tubes in each ring are spaced uniformly apart. Each tube in each ring is located circumferentially midway between the two adjacent tubes of each neighboring ring and is separated from each of the two adjacent tubes in each adjacent ring by a ligament distance h. The distance h is held constant for all tubes in the set, by varying the radial spacing between rings, and the distance between any two adjacent tubes in any ring of the set is made greater than or equal to 2 h. The ligament gaps h which are constant therefore determine the minimum flow area between adjacent rings, and therefore the mass flow velocity through the tube bundle is constant.

Abstract: In the purification of gases generated in metallurgical and similar furnace operations, the impurities include solid particles and compounds or elements which are gaseous at the furnace temperatures and only form solid or liquid at temperatures approaching ambient conditions. Proper cleaning therefore requires cooling of the gases to at least the water dew point to cause these impurities to form as particles or droplets. This invention describes an apparatus for collecting such particles or droplets in which a charging device and condensation equipment are combined to provide a simple, yet effective apparatus at a fraction of the cost of conventional apparatus.
