Title: Treating oil contg. industrial wastes - by ultrafiltration and-or reverse osmosis in closed circuit with incinerator
Inventor: NODA MITSUHIKO
IPC: B01D53/34
Filed: 1975-11-06
Abstract: Effluents contg. combustible org. impurities (oil) can be treated by thickening through ultrafiltration and/or reverse osmosis, followed by burning the thickened fluid. The filtrate from ultrafiltration or diluted soln. from reverse osmosis is used in a closed circuit to cool or wash the flue gases from the combustion, and to decompose the org. components contained in the filtrate. This system has a very low power consumption, just for recirculation and thickening. The thickened residue requires no auxiliary fuel for combustion. The furnace can be kept small because excess water has been removed, and few waste gases are produced. The absence of active carbon filters saves cost, and the process is a closed circuit, producing no pollution of the drainage system.

Title: Sulphuric acid mfr. by three-stage contact process - using pure sulphur di:oxide and oxygen in first stage, reducing plant size and cost
Inventor: STAUFFER ADOLF DIPL CHEM
IPC: C01B17/765
Filed: 1976-10-22
Abstract: In the first stage, much of the sulphur dioxide is oxidised catalytically, with addn. of oxygen, to sulphur trioxide, which is sepd. from the unreacted sulphur dioxide. Then the sulphur dioxide in the exit gas from the first stage is oxidised catalytically, with addn. of oxygen and sufficient air to give an exit gas with the compsn., after sepn. of much of the sulphur dioxide, of a partially catalytically oxidised gas, w.r.t. SO3, SO2 and O2 content, as obtd. in a S combustion gas with the usual sulphur dioxide concn. In the third stage, the exit gas from the second stage is processed to sulphuric acid in the conventional manner. The process can be carried out with relatively small and therefore cheaper plant, since the total vol. of the gas is reduced by the absence of inert gases. The addn. of air in the second stage prevents waste of costly pure oxygen. In an example the process was carried out as described, using 4- part first and second stages. The overall conversion was 99.98%. The output from the individual plants was 900, 250 and 10 t/day, cf. 250, 12 and 10 t/day if the same plants were used conventionally.
