Abstract

Kristal sodyum karbonat, bikarbonat veya sülfit hazırlamak için bir işlemde suda çözünür katışkılan çıkarmak için bir magnezyum muamelesi. Bu katışkılan içeren bir atık bir magnezyum bileşiğiyle muameleden geçirilerek saflaştırılmış bir çözelti oluşturmak için çıkarılan suda çözünmez bir madde oluşturulur. Muamele atık ve isteğe bağlı olarak kalsine edilmiş trona içeren bir çözelti üzerinde uygulanabilir. Saflaştırılmış çözelti kristal soda külü oluşturmak için bir besleme malzemesi olarak kllanılabilir ve/veya S02 veya C02'yle reaksiyon yoluyla kristal sodyum sülfit veya bikarbonat üretmek için bir tepkime maddesi olarak kullanılabilir. Tercih edilen düzenlemelerde, atık bir arıtma çözüntüsü veya zayıf çözüntü, kullanılmış bir katı veya bunların kombinasyonlarını içerebilir. Suda çözünür katışkılar silikatlar ve/veya köpük oluşturucu organik maddeler olabilir ve atık sodyum bikarbonat, sodyum ses kuikarbonat ve/veya bir veya daha fazla dekahidrat gibi sodyum karbonat hidrat içerebilir.
