Aromatic complex: A case study for relief load estimation of a heat integrated refinery unit

Refineries are moving from fuels to chemical production as the demand for fuel derived from crude oil declines in the near future.

Refineries are moving from fuels to chemical production as the demand for fuel derived from crude oil declines in the near future. Conventional fuel-producing refineries are being targeted to reconfigure to produce more chemicals. Integration with an aromatic complex is one way to produce the chemicals for an oil-to-chemicals complex and will likely see wide industrial application in the coming years. In an aromatic complex, aromatic compound producing units are closely integrated with one another to increase the energy efficiency of the entire complex. In the case of a common utility failure like power or cooling water, when the relief load is generated from the entire refinery, the calcul
