I guess even a very stupid guy can make an automated still loose its patience or balance. Or maybe it is better to say: the excitement of the new still threw me off balance!
What happened? I fired her up. She heated up in 40 minutes. Then column stabilization took place. 15 minutes of seeing temp in the to of the column drop steadily. Fores were bled off and then normal collection started. And stopped. I heared some engines (the valves) clicking. Had to wait some time before production started again. At a relative low speed, but it started. For some time … and then it stopped again.
I started looking at the computer and this is what happened. Temperature in, at the bottom of the column rose quickly from 89 to 95 degrees. Machine stops and let the temperature drop to normal conditions (89 degrees) and starts again.
So actually the machinery is doing its job and the automation is kicking in when it needs to do so.
What happened? Or what do I think happened? I flooded the column. That’s the only explanation I can think of for the sudden rise in temperature of vapour in.
How can that happen? Well, if I would tell you I forgot to de gas my wash, would that make sense?
Sorry guys, for fucking up this run. I will restart soon.
To make up, a picture of the computer while stabilizing. You can read it is stabilizing the column. The vapour in temperature is 91.8 degrees C. That’s the vapour entering at the bottom of the column. T_pe is the cooling water temperature: it’s 17 degrees. The current temperature in the top of the column is 79.5 degrees. When I took this picture, stabilization would stilltake 13:27. You could see the temperature drop steadily.
By the way, to hear the valves clicking, doing their work, that’s real fun.
