Abstract:

Taking the high-temperature blended asphalt storage tanks in a refining and chemical enterprise as an example, combined with the physical properties of asphalt and relevant environmental protection requirements, the tank farm process, pump configuration and control scheme for heating medium are clarified according to the feeding relationship between upstream and downstream units. For high-temperature heavy oil storage tanks, nitrogen sealing systems and oil and gas collection systems need to be equipped, and the pipeline installation design is introduced from the aspects of pressure safety relief, purging settings and stress analysis. The key points and difficulties in storage and transportation design of tank farm are summarized, which provide a reference for the design of tank farm related to deodorization treatment of high-temperature heavy oil storage tanks in the future.
