The electronic version of the book is available for download in the Soda Ash Information Sharing Area. http://bbs.hcbbs.com/thread-13140-1-2.html ) True or False Question 1. Changing the gas to produce alkali changes the carbonation process into the decarburization process of ammonia synthesis. ( ) 2. Changing gas soda production requires appropriately increasing the operating pressure of the carbonation process. ( ) 3. Increasing the partial pressure of gas phase carbon dioxide must be achieved by increasing the concentration of carbon dioxide. ( )
