摘要:
The invention relates to a process (4) for purifying a product (1) contaminated with nitrosamines from an operating plant (2). The contaminated product (1) is heated to a temperature T at which the nitrosamines are thermally destroyed. The temperature T is set at a higher level than the maximum temperature in the operating plant (2), and maintained for a residence time t. The invention also relates to an apparatus (7) for regeneration of a nitrosamine-contaminated product (1) from a CO 2 capture plant.
