What is distillation temperature
Thread Content
This post was last edited by dongliangsir on 2013-12-23 20:40. What is the distillation temperature at 10%?； 50% ； 90% distillation temperature ； What does that mean? Is it by dividing the temperature equally between the boiling point and the freezing point? What is the standard for the flowing oil product? Is it calibrated using temperature or obtained through online analysis? How else could it be determined? How to measure the optimal load of a reactor? Is the oil grade for each layer determined by the temperature of the side line at that layer?
What issues should be noted during study*? Which process (or device control scheme) is most helpful for me?
I’ve looked at many surge formulas for compressors, and after comparing them all, it seems that it’s always related to the relationship between inlet pressure and flow rate. Although surge involves many parameters, none of them are used. It is also calculated using the outlet pressure, but in the end it is converted back to the inlet pressure. Could someone please pay attention to this? Thank you
What temperature corresponds to what length, and for what medium? Are there any data available? Thank you all for your help!
100 mL of the oil sample is placed in a standard distillation flask and heated at a specified rate; the temperature of the gas phase at the moment the first drop of condensate appears is known as the initial boiling point. Subsequently, as the temperature gradually increased and distillation continued, the temperature of the gas phase at the points when 10 ml, 20 ml, 30 ml, and so on up to 90 ml of distillate had been collected was recorded. These temperatures are referred to as the 10%, 20%, …, 90% distillation temperatures. The highest gas phase temperature during distillation is the dry point. Crude oil is a very complex mixture.
The distillation temperature refers to the temperature at which the side-stream oil is distilled or extracted from the main fractionation tower.
