(The questions in this issue are taken from page 4 of \"Technical Worker Training Question Bank – Soda Ash Production Operators.\" An electronic version of this book is available for download in the soda ash information sharing area: http://bbs.hcbbs.com/thread-13140-1-2.html) Fill-in-the-blank questions: 6. Theoretically, to produce 1 ton of soda ash and 1 ton of ammonium chloride, (100%) () m3 of carbon dioxide is required (under standard conditions). 7. Carbon dioxide dissolves in water to form ( ), and its solubility increases as the temperature rises ( ). 8. The main sources of carbon dioxide are ( ), ( ), ( ), ( ). 9. Since limestone contains ( ) and ( ) oxide impurities, it tends to form lumps during calcination. 10. The concentration of CO2 gas produced by the calcination of limestone is generally above ( ).
6. Theoretically, to produce 1 ton of soda ash and 1 ton of ammonium chloride, 221.3 m3 of carbon dioxide (100%) is required under standard conditions. 7. Carbon dioxide dissolves in water to form (carbonic acid), and its solubility (decreases) as the temperature rises. 8. The main sources of carbon dioxide include (synthetically produced decarburization gas), (lime kiln off-gas), (flue gas from industrial processes), and (by-products of alcohol fermentation). 9. Since limestone contains impurities of (iron) and (silicon) oxide, it tends to form lumps during calcination. 10. The concentration of CO2 gas produced by the calcination of limestone is generally above (38%).

6. Theoretically, to produce 1 ton of soda ash and 1 ton of ammonium chloride, 221.3 m3 of carbon dioxide (at 100% purity) is required under standard conditions. 7. When carbon dioxide dissolves in water, it forms (carbonic acid), and its solubility (decreases) as the temperature rises. 8. The main sources of carbon dioxide include (synthetically produced decarburization gas), (lime kiln off-gas), (flue gas from full-scale production), and (by-product gas from alcohol fermentation). 9. Due to the presence of impurities such as (iron) and (silicon) oxide in limestone, nodulation easily occurs during calcination. 10. The concentration of CO2 gas produced by the calcination of limestone is generally above (38%). 1# chen3jun
