Electronic version of the book can be downloaded here: http://bbs.hcbbs.com/thread-13140-1-2.html I. Fill in the blanks: 1. The process specifications for ammonia brine are: FNH3 should be _______ tt, TCl must not be less than ______ tt, S-2 should be ______ tt; the temperature must be kept below ______ °C. 2. The process indicators for refined brine are: TCl of _____ tt or higher, turbidity of _______ × 10^6 or lower, and temperature of _____ °C. 3. The task of the ammonia absorber is to convert the ______ and ______ absorbed from the ammonia stripping system into ammoniated brine containing TCl at _____ tt, FNH3 at ______ tt, and at a temperature of approximately ______°C or lower, for use in carbonation.
1. The process specifications for the ammonia brine are: FNH3 should be __100~106_____ tt, TCl must not be lower than ___88___ tt, S-2 should be __0.015~0.03____ tt, and the temperature should be kept below __40____ °C. 2. The process indicators for refined brine are: TCl above __104.5___ tt, turbidity below __40_____×10^6, and temperature at __40___°C. 3. The task of the ammonia absorber is to convert the __refined brine__ that has absorbed __carbon dioxide__ and __ammonia__ from the ammonia stripping system into ammoniated brine containing TCl at __80–90__ tt, FNH3 at __100–103__ tt, and at a temperature of around __40__°C or lower; this ammoniated brine is then used for carbonation.

1. The process specifications for the ammonia brine are: FNH3 should be _100–106__ tt, TCl must not be lower than __88__ tt, S-2 should be __0.015–0.03__ tt, and the temperature should be kept below _40_°C. 2. The process indicators for refined brine are: TCl_104.5__tt or higher, turbidity of __40__×10^6 or lower, and temperature of __40__°C. 3. The task of the ammonia absorber is to convert the _ammonia_ and _carbon dioxide_ absorbed from the ammonia stripping system by the _refined brine_ into ammoniated brine containing TCl of _88–90_ tt, FNH3 of _100–103_ tt, at a temperature of approximately _40_°C or lower; this ammoniated brine is then used for carbonation.

1. The process specifications for the ammonia brine are: FNH3 at 100–106 tt, TCl not less than 88 tt, S-2 at 0.015–0.03 tt, with the temperature controlled below 40°C. 2. The process indicators for refined brine are: TCl above 104.5 tt, turbidity below 40×10⁻⁶, and temperature of 40°C. 3. The task of ammonia absorption is to convert the refined brine that has absorbed ___carbon dioxide___ and ___ammonia___ from the ammonia stripping system into ammoniated brine containing TCl at __80–90__ tt, FNH3 at __100–103__ tt, and at a temperature of around ___40___°C or below; this ammoniated brine is then used for carbonation. 1# 9067jxhuas
