While it has been largely supplanted by other methods (like the Hou process) in many places, some plants still use it, and it remains a historically pivotal industrial technique.
The primary raw materials are brine (sodium chloride), limestone (calcium carbonate), and ammonia, which acts as a catalyst and is recycled.
Calcium chloride is a significant by-product, often considered a waste product that can pose disposal challenges.
