I would like to ask some questions regarding the initial startup of atmospheric and vacuum distillation
Thread Content
How long does the diesel cycle generally need to continue after it is established? Is there a schedule chart for the start-up of atmospheric and vacuum distillation units that I can refer to?:D
What’s the scale? I can upload one with 3.8 million for you to take as a reference
This is the production schedule set by my refinery for this year; you might find it useful as a reference
The diagram is divided into 8 stages: device testing, oil introduction and circulation, electro-dehydration, heating the furnace for dehydration, closed-loop circulation at 250 degrees for heat tightening, switching to normal pressure, switching to reduced pressure, and adjustment operations; I’m typing this out manually in case it’s not clear enough for you
Purpose of diesel combined operation during the first start-up: 1. To remove water accumulated in the equipment, furnace tubes, and pipelines； 2. Further examine the operating conditions of the motor, pump, and instruments at a certain temperature ； 3. Due to its good permeability, diesel is used to further check for leaks in the equipment and pipelines of the circulation system ； 4. Inspect the operation of the heating furnace’s fuel system and the usage of the burners ； 5. Further provide technical training for personnel performing the tasks. Both diesel transportation and handling involve processes of heating and cooling, and there are also numerous inspection and testing procedures, so it takes at least about 3 days.
