Acetylene loss amount after spray cooling of the calcium carbide slurry supernatant
Thread Content
What is the amount of acetylene lost after the calcium carbide slurry supernatant is cooled by spraying? I would appreciate some advice from fellow sailors, thank you!
Solubility of acetylene in water at different temperatures: Temperature (°C) – Solubility. 0 °C: 1.73; 25 °C: 0.93; 70 °C: 0.25. 5 °C: 1.49; 30 °C: 0.84; 80 °C: 0.15. 10 °C: 1.31; 40 °C: 0.65; 90 °C: 0.05. 15 °C: 1.15; 50 °C: 0.50; 20 °C: 1.03; 60 °C: 0.37. It can be seen from this table what temperature can be achieved after spray cooling. This post was last edited by shizhiyong001 on 2009-2-25 10:57.]
According to the theory for the second floor, lower temperatures result in higher solubility; once the temperature drops after spraying, acetylene should be absorbed. Spraying is not just for cooling down
It should be the total amount of acetylene lost during the discharge of the slurry; then, as the temperature drops, another portion of the acetylene dissolves back into the supernatant (the amount that dissolves is based on the total amount that was lost). Is that the right way to understand it?
What the moderator said makes sense; one way to save energy is to keep the generator temperature above 80°C in order to reduce dissolution losses.
Perhaps everyone has misunderstood my question. What I’m asking is: what is the change in the acetylene content in the supernatant before and after spray cooling? In fact, before entering the spray cooling tower, the supernatant may contain saturated dissolved acetylene; so, what is the acetylene content in this supernatant after spray cooling?
I have monitored the acetylene concentration in the slurry supernatant after cooling, and it is generally between 4-10 ppm
Thank you! This way I can estimate the amount of acetylene lost after cooling.
