Thread Content
This post was last edited by “Back to Cambridge” on January 27, 2016, at 13:36. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their fundamental knowledge in chemical engineering. Subsequently, series such as “Principles 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 points, with an additional 4 wealth points for correct answers~~~ Short answer question: What are the reasons for insufficient dissolved oxygen in water? Answer: 1) Abnormal operation of the deaerator, insufficient opening of the deaerator exhaust valve; 2) Leaks at the inlet of the feed water pump; 3) Defects in the internal components of the deaerator; 4) Air leakage due to leaks in the sampling pipes; 5) Insufficient addition of diamine to the feed water; 6) Expired analytical reagents or inaccurate instruments.
What are the reasons for insufficient dissolved oxygen in the feed water? The main reasons for insufficient dissolved oxygen in the feed water are: (1) Abnormal operating parameters of the deaerator (temperature, pressure). (2) Excessively high dissolved oxygen at the deaerator inlet. (3) There are defects inside the deaerator unit. (4) Large load fluctuations result in increased water replenishment. (5) The exhaust valve opening is not appropriate.
