Abstract
MANY problems are associated with safety in air separation plants, and various theories have been proposed as to the cause, and avoidance, of explosions1–3. The primary cause is known to be the accumulation of atmospheric pollutants, condensed from the air stream at the very low temperatures involved in liquid air distillation, particularly in the presence of high oxygen concentration. The nitrogen plants designed by this company minimize possible hazard by limiting the maximum oxygen concentration to 31 per cent.
