Abstract
Söndürme kolonu pH?ının kontrol altına alınması için bir işlem bir veya daha fazla söndürme kolonuna ait bir söndürme kolonu atığında pH?ın kontrol altına alınması için söndürme kolonuna asit eklenmesini içerir. Bir yönü itibarıyla işlem söndürme kolonu kondensatına ait bir pH?ın ölçülmesini ve kondensatta yaklaşık 3.5 ila yaklaşık 7 pH?ın sağlanması için söndürme kolonuna eklenecek bir asit miktarının ayarlanmasını içerir. Kondensat pH?ının ölçülmesi söndürme kolonuna asit ilavesinin kontrol altına alınması için tutarlı ve hatasız bir usul sağlar.
