Seeking help with distillation tower operation
Thread Content
The diesel hydrodesorption tower uses steam as the stripping medium; when all other conditions remain constant, increasing the amount of stripping steam reduces the vapor pressure of the oil and gas, thereby lowering the boiling point of the product at the bottom of the tower and causing a decrease in the temperature there. At this point, will the flash point of the diesel product at the bottom of the tower decrease accordingly? In other words, at the temperature resulting from the drop in bottom temperature, is it necessary to raise the bottom temperature back to its previous level in order to ensure that the flash point meets the requirements? How should we understand the principle behind this part?
I’m not from the industry; there are established procedures in place. I’ll share a few layman’s terms for reference. 1. Hypothesis: Is steam the heat source for the rising vapor in distillation? “If the amount of stripping steam is increased,,,,”do all these theoretical analyses conform to the principles of the process? 2. It should be comprehensively understood based on the overall operating principles of the distillation tower, taking into account the physical and chemical properties of the materials, the process parameters at various control points, as well as the state within the specified parameter ranges. This is because the characteristic of a distillation tower is to produce within a certain range; outside that range, the product requirements cannot be met. For reference.
