摘要： Anhydrous liquid sulfur dioxide is recovered from environmentally unsuitable vapor or liquid streams comprising water, sulfur dioxide and carbon dioxide. The vapor streams are fed into an absorption zone and contacted with a lean liquid water stream. A resulting sulfur dioxide rich water stream is passed into a first fractionation column utilized in part as the stripper column which produces the lean water stream. A sidecut stream removed above the feed point is passed into a second fractionation column, and the overhead vapor of the first column is subjected to two stages of partial condensation to aid carbon dioxide rejection. Anhydrous sulfur dioxide is removed as a liquid sidecut of the second column, and the net overhead vapor of the second column is preferably passed into the overhead system of the first column after a partial condensation.

摘要： An evaporator for converting a liquified gas such as chlorine into a superheated gas. The evaporator is constituted by a pressure vessel having a heat pipe vertically mounted therein, the lower end of the pipe projecting below the vessel and being coupled to a heat source whereby thermal energy from the source is transferred to the interior of the vessel. Liquified gas is fed into the vessel through an inlet pipe to form a pool in the lower zone thereof, in contact with the heat pipe. The gas evaporated from the heated pool is discharged through an outlet pipe.

摘要： Ultrasonic atomizer nozzle assembly for atomizing waste sulfuric acid in a cracking furnace in which the acid feed stream is mechanically broken up by a stationary or rotating type atomizer into a coarse spray and an annullarly arranged ultrasonic generator further atomizes the coarse spray into microscopic particles. The ultrasonic generating gas is deflected into the ultrasonic resonance chamber and the coarse spray is either centrally or annularly positioned relative to the ultrasonic field. An annular gas buffer may be provided around the atomizer. The nozzle assembly is mounted in the ceiling of a furnace having a gas flow constricting member spaced from the ceiling 1-4 times the diameter of the furnace.

摘要： Substantially sulphur-free fuel gas is produced from coal by gasification of particles of coal with a steam/oxygen mixture at an upstream end of a bed of fluidized particles containing an alkaline earth metal oxide, sulphur from the coal being fixed in the particles as alkaline earth metal sulphides. The bed particles travel generally downstream towards a regenerator, and at the downstream end, oil is injected into the bed and gasified to compensate for the reduced coal concentration at the downstream end whereby to avoid dilution of the fuel gas. Bed material from the downstream end is contacted with oxygen or air to convert sulphides to oxides, SO2 being liberated and recovered and the oxide-containing regenerated particles are returned to upstream end of the bed.
