Abstract: In order to solve the problems such as environmental protection, safety, energy consumption, land occupation of viscous oil unloading process with self-unloading tank, the viscous oil unloading process without self-unloading tank is developed. After cancelling self-unloading tank,DN600 large diameter manifold is used as buffer tank in front of pump, twin-screw pump is used for transferring oil, and double-flange remote level gauge is set to predict the completion time of unloading. There is no need to set the supporting facilities such as the exhaust treatment of the self-unloading tank and the high point exhaust pipe of manifold. After applying the new process, it has reached the design capacity of unloading 1.0 Mt fuel oil per year, with the advantages of zero discharge on site, high unloading efficiency, predictable completion time, small land occupation, low investment and operation costs.
