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 ) Fill in the blanks 1. The joint alkali production method uses the ( ) process to crystallize ( ) contained in the alkali production mother liquor to produce products. This method can obtain two products ( ) and ( ). 2. The characteristics of the joint alkali production method are ( ). 3. The production of joint alkali production method is divided into two processes. The process of producing soda ash is called ( ) or ( ) ； The process of producing ammonium chloride is called ( ) or ( ).

1. The joint alkali production method uses a (chemical) process to crystallize the (ammonium chloride) contained in the alkali production mother liquor to produce products. This method can obtain two products (soda ash) and (ammonium chloride). 2. The characteristics of the joint alkali production method are (mother liquor circulation). 3. The production of joint alkali production method is divided into two processes. The process of producing soda ash is called (1 process) or (alkali production process) ； The process of producing ammonium chloride is called (2 process) or (ammonium production process).
