【Daily Question】Chemical Engineering Principles 359: Deoxygenation of Boiler Feed Water (April 12)
Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering,\" \"Mass Transfer and Separation,\" \"Thermodynamics in Chemical Engineering,\" and \"Chemical Process Engineering.\" We hope you will give it your active support! Wishing you a happy Christmas! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying to the post, and the topic will be closed after 1 day ! To encourage everyone’s continued participation this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: What are the different methods of deoxygenating boiler feed water? Thermal deoxidation and chemical deoxidation
Thermal deoxidation, adsorption deoxidation, sponge iron deoxidation, chemical deoxidation
1. Thermal deoxygenation of water 2. Chemical deoxygenation of water: (1) Hydrazine deoxygenation; (2) Ferrous sulfate deoxygenation; (4) Scrap steel deoxygenation 3. Vacuum deoxygenation
Atmospheric thermal deoxidation, analytical deoxidation, sponge iron deoxidation, chemical deoxidation.
What are the different types of boiler feedwater deoxidation? Answer: There are liquid deoxygenation methods and gas deoxygenation methods
1. Thermal deoxidation of water 2. Chemical deoxidation of water: (1) Hydrazine deoxidation; (2) Ferrous sulfate deoxidation; (3) Sodium sulfite deoxidation; (4) Steel scrap deoxidation 3. Vacuum deoxidation
Thermal deoxidation, vacuum deoxidation, iron scrap deoxidation, sponge iron deoxidation, sodium sulfite deoxidation, desorption deoxidation
Two methods, one physical and one chemical, I guess.
There are four types: thermal deoxidation, analytical deoxidation, sponge iron deoxidation, and chemical deoxidation.
