Chlorine corrosion encountered with the generation and processing of LURGI pressure gasification gas made from coalAfter a brief period of operation, a pressure gasification plant was found to be affected by corrosion of the apparatus which could be mainly attributed to chlorine attack. Chlorine reached the generators in raw coal containing chlorides. A number of measures designed to prevent such corrosion are described; but it was only through a cladding of highly alloyed chrome-nickel steel that satisfactory operating periods could be obtained. The paper also describes damage by chlorine to a tar distillation plant, to the ammonium sulphate plant and a pressure refining plant for petrol, as well as measures designed to prevent such damage.
Notes:
Nach kurzer Betriebszeit trat in einer Druckvergasungsanlage Korrosion der Apparate auf, die überwiegend auf Chlor-Angriff zurückgeführt werden konnte. Chlor gelangte mit einer chloridhaltigen Rohkohle in die Generatoren. Verschiedene Maßnahmen zur Verhütung des Angriffs werden beschrieben; erst Panzerung mit hochlegiertem Chrom-Nickel-Stahl führte zu befriedigend langen Betriebszeiten. Weiter werden Schäden durch Chlor in der Teerdestillationsanlage, dem Ammonsulfatbetrieb und in einer Druckraffinationsanlage für Benzin und Maß nahmen zu ihrer Verhütung beschrieben.
