【Daily Question】Chemical Engineering Principles 427: Saturated Steam (September 11)
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 continued participation from everyone this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What is the relationship between the solubility of saturated steam in silicon and the pressure of the saturated steam? Increases as pressure increases
Relationship: Increases as pressure increases.
In the treatment of boiler water, the parameter requirements regarding silicon are mainly related to the boiler itself and energy conservation; its impact on the quality of the water itself is relatively minor. Silicon is one of the main causes of scaling in boilers and the entire system. The mechanism of scaling is as follows: H2SiO3 ---> H+ + HSiO3-; MgOH+ + HSiO3- ---> MgSiO3 + H2O
