【Daily Question】Chemical Engineering Principles 302: Operation of Anion Exchange Resins (January 22)
Thread Content
This post was last edited by “Back to Cambridge” on January 27, 2016, at 15:04. Starting today, the Chemical Engineering Theory section will launch the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth rewards, with an additional 4 rewards for correct answers. Short answer question: Briefly describe the operation steps for bringing a cation exchange resin bed into use. Answer: 1) Manual inlet valve, pneumatic inlet valve, and exhaust valve for the open-bed reactor. 2) When water overflows from the exhaust valve, open the normal wash drain valve and close the exhaust valve. 3) When the Na concentration in the effluent is ≤100 ug/l, open the manual effluent valve and the pneumatic effluent valve, and close the normal wash drain valve
1) Open the manual inlet door, pneumatic inlet door, and exhaust door of the anion bed, and start the intermediate water pump. 2) When water overflows from the air valve, open the forward wash drain valve and close the drain valve. 3) When the outlet water conductivity is less than 10 us/cm and SiO2 is less than 20 ug/l, open the manual outlet door and the pneumatic outlet door.
Briefly describe the operation steps for putting the cation exchange resin bed into use. Answer: 1) Manual inlet valve, pneumatic inlet valve, and exhaust valve for the open-circuit bed. 2) When water overflows from the exhaust valve, open the normal wash drain valve and close the exhaust valve. 3) When the Na concentration in the effluent is ≤100 ug/l, open the manual effluent valve and the pneumatic effluent valve, and close the normal wash drain valve.

1) Manual inlet door, pneumatic inlet door, and exhaust valve for the open-type bed. 2) When water overflows from the exhaust valve, open the normal wash drain valve and close the exhaust valve. 3) When the Na concentration in the effluent is ≤100 ug/l, open the manual outlet door and the pneumatic outlet door, and close the normal wash drain valve
