(The question for this issue is taken from page 70 of \"Technical Worker Training Question Bank – Soda Ash Production Operators.\" An electronic version of this book is available for download at the soda ash information sharing site: http://bbs.hcbbs.com/thread-13140-1-2.html) Short-answer question: 1. The synthesis ammonia shift gas is generally purified using ( ) or ( ) methods, and the concentration of carbon dioxide obtained is higher than ( ). 2. In the process of converting gas into soda ash, the concentration of carbonated carbon dioxide gas is restricted; its concentration is generally ( ). 3. In the conversion gas process for soda production, （ ） is used to increase the absorption rate of carbonated carbon dioxide. 4. One of the key issues in ammonia synthesis using shifted gas is resolving the conflict between the ( ) in the shifted gas returned to ammonia synthesis and the ( ) in the carbonation effluent. 5. In the production of soda from transformed gas, there are also issues related to the purification of exhaust gases ( ) and their recycling ( ).
1. Physics, Chemistry, 98%； 2. 20%~28% ； 3. Increase the carbonation operation pressure ； 4. Purity, carbonation level ； 5. Dilute ammonia water, calciner gas
1. Physics, Chemistry, 98% 2. 20%–28% 3. Increase the pressure during carbonation process 4. Purity, degree of carbonation 5. Dilute ammonia water, flue gas from calcination furnace
1. The syngas from ammonia synthesis is generally purified by (physical) or (chemical) methods, resulting in a carbon dioxide concentration of over (98%). 2. In the process of converting gas into soda ash, the concentration of carbonated carbon dioxide gas is limited, with a typical concentration ranging from (20% to 28%). 3. In the transformation gas soda production process, the absorption rate of carbon dioxide during carbonation is increased by (raising the carbonation operation pressure). 4. One of the key issues in converting gas for alkali production is resolving the conflict between the (purity) of the gas returned to ammonia synthesis and the (carbonation level) of the liquid obtained through carbonation. 5. In the conversion gas soda production process, there are also issues to address regarding exhaust gas purification for product production (dilute ammonia water) and the recycling of gases (from calcination furnaces).

1. The synthesis ammonia shift gas is generally purified by (physical) or (chemical) methods, resulting in a carbon dioxide concentration higher than (98%). 2. In the conversion gas soda-making process, the concentration of carbonated carbon dioxide gas is restricted, with a typical concentration ranging from (20–28%). 3. In the transformation gas process for alkali production, the absorption rate of carbon dioxide during carbonation is increased by (raising the carbonation operation pressure). 4. One of the key issues in ammonia synthesis gas-based soda production is resolving the conflict between the (purity) of the gas returned to ammonia synthesis and the (carbonation level) of the carbonation extract. 5. In the conversion gas-based soda production process, there are also issues to address regarding exhaust gas purification for product production (diluted ammonia water) and the recycling of gases (from baking furnaces).
