Are there diesel hydrofining reactors that use fuel oil as fuel?
Thread Content
Due to gas balance issues, our company now requires that the diesel hydrocracking reactors use fuel oil as fuel (they are equipped with fuel oil nozzles at design time). I was wondering if other companies face a similar situation Also, does burning oil have any adverse effects on the reaction furnace?
When using oil, it’s difficult to control the temperature, and the operation is rather challenging. It must also be used in conjunction with misted steam, and is greatly affected by steam pressure. We converted our other stoves to oil-gas dual use, but we didn’t dare to modify this one.
There are now requirements regarding smoke emission; can burning oil meet those standards?»
Moreover, burning oil makes it easy to form coke that blocks the burner
It is recommended to use gas instead; it does not meet environmental standards, it can easily cause clogging of the burner, and it is more difficult to operate. The reaction temperature requirements for hydrorefining are also high, making it unsuitable for fuel oil
The nitrogen oxide levels in the exhaust gases from oil burning are certainly not within acceptable limits, but since environmental regulations do not require this yet, using oil for heating is not a problem for the time being.
Very few oil burners are in use; the load on the reactors is currently very low. It’s basically sufficient if the reaction is exothermic
Our device is designed in accordance with National Standard IV requirements. Since these standards have not been made mandatory, diesel meeting National Standard III standards is actually used; as a result, both the reaction temperature and the temperature increase during the reaction are very low, which leads to a high load on the reaction furnace.
