Adjustment of the dry point control parameter for gasoline
Thread Content
The workshop supervisor requested that the control parameters for the dry point of gasoline be adjusted; from 196–206 before, they were changed to 190–200 now. Will this adjustment result in a lower yield of gasoline? What is the purpose of this adjustment? Thank you. It’s my first time dealing with this kind of knowledge, so I don’t quite understand it
The gasoline yield decreased, while the diesel yield increased； The control of the dry point is related to the results from the tank area samples; it’s possible that the dry point in those samples is too high, and it is necessary to adjust it by reducing the dry point on the equipment.
A single unit, such as a catalytic unit for processing gasoline, is only part of the gasoline blending tank; other types of oils are also added to this tank. Depending on the requirements for gasoline production, different specifications apply to it, and one important parameter is the dry point of the gasoline. The final dry point of the blended gasoline must meet the requirements set for release from the factory, and the dry point of each unit is adjusted accordingly to meet the needs of the gasoline blending tank.
