Abstract

1,088,426. Surface condensers. PRODUITS CHIMIQUES PECHINEY-SAINT-GOBAIN. Dec. 17, 1964 [Dec. 17, 1963], No. 51398/64. Heading F-S. A condensable component is separated by condensation from a hot mixture of gases and vapours, e.g. phthalic anhydride is separated from reaction gases, by introducing the gaseous mixture through pipe 2 into the distribution chamber 4 of a tower, the central portion of which contains metallic hollow rectangular elements 9 arranged vertically in parallel rows and also in stages one above the other up the tower, while cooling fluid flows through the elements. As shown, there are three stages of these vertically-arranged cooling elements, above which there is an uppermost cooling stage 18 comprising horizontal cooling elements. Phthalic anhydride condenses on the cooling elements in the solid state, and the cool gases leave the top of the tower through chamber 15. The cooling fluid flows through the stages in series, either co-currently or countercurrently with the flow of gas. As shown, the cooling fluid enters through connection 13, flows from duct 10 in parallel through the elements of the lowermost stage, and flows via duct 11 and external feeder 14 into the next higher stage. After passing through the uppermost stage 18, the cooling fluid is discharged from the tower, and may be recycled after being suitably cooled. Condensation of vapour in chamber 4 is prevented by means of heating tubes 6. The spacings between the elements 9 in each of the higher stages are smaller than those in the lower stages. When the back-pressure in the tower reaches a certain value, the circulation of cold fluid through the elements is discontinued and is replaced by hot fluid, which causes the solid condensate to melt and run down to the bottom outlet. The apparatus may also be used for the condensation to the solid state in the case of naphthalene, camphor, hexachlorethane and maleic anhydride; the tower may also be used for the condensation of maleic anhydride, alcohol or benzene to the liquid state. Heatexchange fluids referred to are: air, water, steam, brine, oil, and molten metal. Various materials of construction for the tower are specified, e.g. stainless steel, reinforced cement, brick, siliceous cast iron, aluminium.
