Abstract
This utility model discloses a treatment device for mitigating coking of atmospheric residue oil, belonging to the field of petroleum processing technology. The device includes a vacuum furnace and a vacuum tower. The vacuum tower has a packing layer inside. Its key feature is that it further includes a hydrogenation reactor and a gas-liquid separator. The outlet of the vacuum tower is connected to the inlet of the hydrogenation reactor via a pipeline. The outlet of the hydrogenation reactor is connected to the inlet of the gas-liquid separator via a pipeline. The liquid phase outlet of the gas-liquid separator merges with the atmospheric residue oil feed stream and is then connected to the inlet of the vacuum furnace via a corresponding pipeline. The outlet of the vacuum furnace is connected to the inlet of the vacuum tower via a pipeline. This utility model, by adding a hydrogenation reactor and a gas-liquid separator and reorganizing the pipeline connections, allows the wash oil to be pretreated before mixing, fundamentally improving the thermal stability of the oil, reducing the coking tendency of the residue oil, and extending the operating cycle of the device.
