Problems with the vacuum-operated carburetor pump
Thread Content
Have any of you’s atmospheric and vacuum distillation units been equipped with a vapor oil pump? It has been found that some units are equipped with this pump, which draws vaporized oil from the final oil collection tank in the vacuum tower. After pressure is increased by this pump, part of the oil is sent to the bottom of the vacuum tower as washing oil, while another part is combined with Line 3 for heat exchange. Is there any principle behind this? Why is this pump installed, and why is it combined with Line 3 within the plant?
Does anyone know? Let’s discuss it together
The main function of this pump is washing; it can vaporize the light components when asphalt is discharged, thereby ensuring that the asphalt product meets the required standards
It makes sense; for an atmospheric distillation tower that produces asphalt, is it necessary to mix this vaporized oil into the asphalt?
