The discussed conversion process of gypsum is not new. It was carried out for the first time in indus-trial scale in Merseburg (Germany) in 1909. That's why it is often called the Merseburg process. The economy of this process is crucial, and it is derived from a relatively sophisticated reactor system, the price for ammonia (rather high) and ...
