What are the measures to increase diesel production, and how can process parameters be adjusted to produce more diesel?
Please discuss how to adjust the process parameters of refining units to increase gasoline production.
Measures to increase diesel production: 1. Lower the dry point of gasoline； 2. Reduce the top of tower temperature, provided that the diesel flash point meets the requirements ； 3. Slightly increase the feed temperature ； 4. Use lighter raw materials ； 5. Use efficient additives ； 6. Use catalysts that produce more diesel, etc.
Firstly, the crude oil is key; secondly, it’s the production scheme. Scheme for producing more gasoline: short reaction time, high reaction temperature, high catalyst activity, high catalyst-to-oil ratio, low reprocessing ratio. Scheme for producing more diesel: low reaction temperature, high reprocessing ratio
It depends on what the device is; different devices require different solutions.
The metrics can be improved, that is, by doing a bit more work
First, it is necessary to clarify what production facility you are referring to. Overall for the entire plant, catalytic devices can be used to reduce the reaction temperature; in the diesel production process, other devices are employed to lower the dry point of gasoline to around 160 degrees, thereby expanding the diesel boiling range. In summer, the diesel extraction temperature can also be increased to transfer some of the heavy diesel components into light diesel, which helps to reduce the catalytic load. Reduced-grade paraffin oil can also be refined and then blended into light diesel.
Please provide more details, and it would be best to include the specifications of the refined oil products, so that everyone can discuss them. If possible, talk about the device as well; it would be great if there were delayed coking.
The term ‘moderators’ refers to all the means available in a refinery, including, of course, all the equipment and other facilities.
