摘要： An apparatus for heat-transfer between a hot gas and an aqueous solution including means for combusting a material for producing a hot combustion gas, a duct connected at one end of the combustion means, and a concurrent flow gas-liquid contacting unit, such as a venturi scrubber and either an, empty tower or a packed tower hermetically connected with the other end of the duct. The apparatus is characterized by connecting means interposed between the duct and the contacting unit, a solutioninjecting port opening into the contacting unit at a position below the connecting means for injecting an aqueous solution into the unit for direct contact with the hot gas therein, and a water-feeding port provided over the solution-injecting port.

摘要： A rotary kiln type solid waste incinerating system and a method for continuously and efficiently incinerating a large amount of solid waste are disclosed. A vortex is established within the rotating cylinder of the kiln by injection of air to vigorously agitate the atmosphere within the kiln and thereby ensure uniform distribution of oxygen and efficient combustion. In one embodiment, the system includes an air induction duct which is approximately concentric with the rotary cylinder and which has a plurality of air injection nozzles at suitable intervals along its length for injecting air into the rotary cylinder in a direction tangential to its inner surface to establish a vortex.

摘要： A wet-type desulfurization process is disclosed for purifying gases containing hydrogen sulfide and hydrogen cyanide contaminants. The gas is washed with an alkaline aqueous solution to absorb the contaminants. The wash solution containing the dissolved contaminants is oxidized to form free sulfur from any hydrosulfide salt that might be present. The sulfur is removed as a precipitate. The oxidized wash solution is then roasted to convert the thiocyanates, sulfates, sulfites, and thiosulfates to carbonates, sulfides and hydrosulfides. These salts are then recovered in an aqueous solution, which solution is recycled for use in the absorption or oxidation steps.

摘要： The sulfur component of the waste gas (which is called tail gas) which issues from the Claus process is effectively recovered and prevented from being released into the atmosphere by a method which comprises oxidizing by combustion the waste gas (hereinafter referred to as ''''tail gas'''') for thereby converting the whole sulfur component into SO2, thereafter mixing the resulting gas with a reducing combustion gas for thereby lowering the residual oxygen content of said tail gas to substantial absence, subsequently cooling the resulting gas containing substantially no oxygen and then introducing the cooled gas into a liquid capable of absorbing SO2, heating the resulting SO2absorbed liquid and recovering the SO2 consequently liberated from the liquid, and circulating the recovered SO2 to the Claus process.

摘要： A method for separating and recovering an objective component from a crude liquid by a membrane in a semi-batch system, includes the steps of: at least two stages of adding a washing liquid to the crude liquid stored in a container and mixing the washing liquid with the crude liquid to form a mixture of the crude liquid and the washing liquid, wherein successive ones of the at least two stages are separated by a time lag, wherein the successive ones use washing liquids at different concentrations, in descending order, of the objective component concentration, and further wherein a last one of the plural stages uses only a washing liquid having essentially a zero concentration of the objective component; and for each of the plural stages, performing a step of membrane treatment of the mixture to transfer the objective component from the crude liquid to a permeated liquid.

摘要： Method and apparatus for heating and removing moisture from moist or watery material, wherein a watery material is introduced into one end of a rotating cylindrical drum having a section divided into a number of longitudinally extending compartments including a center compartment and circumferential compartments surrounding the center compartment and each accommodating freely disposed packing members. A hot gas is blown axially through the drum while the packing members in the respective compartments are caused to tumble in contact with the watery material to transfer the sensible heat of the hot gas thereto.
