Oil demand for startup when the hydrogenation unit is first put into operation
Thread Content
As the title suggests, how is the amount of feed oil required at the initial start-up of a hydrogenation unit determined? I saw a hydrogenation unit with an annual capacity of 200,000 tons; they reported needing 5,800 tons of diesel for startup. At my previous workplace, we had a catalytic cracking unit with an annual capacity of 150,000 tons, and for startup we only purchased 500 tons of diesel. Gentlemen, what was the size of your plants when they first started operating, and how much starting oil was used?
The IP related to Sichuan gives off a friendly impression. Sichuan doesn’t have a 150,000-ton catalytic cracking facility either; it’s probably a 150,000-ton hydrorefining plant! 300~500 tons of startup oil is entirely normal. If 5,800 tons of diesel is to be prepared for operation, I guess it must be a diesel plant after all
The amount of startup oil required for the initial operation of a hydrogenation unit usually depends on various factors, such as the unit’s design, processing capacity, and process flow. 5,800 tons of startup diesel per year for a hydrogenation plant with an annual capacity of 200,000 tons may seem like a large amount, but this could be related to the specific processes and design. Previously, your plant’s cracker unit with a capacity of 150,000 tons per year used only 500 tons of diesel for startup; this was probably because the process and equipment requirements for the cracker unit are different from those of the hydrogenation unit. It is recommended to consult the equipment supplier or engineering technicians in detail, as they can provide more accurate calculations and recommendations. At the same time, it is also possible to learn about the oil usage in other similar devices as a reference. .
