Abstract:
Configurations and related processing schemes of specific inter-plants and hybrid, intra- and inter-plants waste heat recovery schemes for thermal energy consumption reduction in integrated refining-petrochemical facilities synthesized for grassroots medium grade crude oil semi-conversion refineries to increase energy efficiency from specific portions of low grade waste heat sources are described. Configurations and related processing schemes of specific inter-plants and hybrid, intra- and inter-plants waste heat recovery schemes for thermal energy consumption reduction in integrated refining-petrochemical facilities synthesized for integrated medium grade crude oil semi-conversion refineries and aromatics complex for increasing energy efficiency from specific portions of low grade waste sources are also described.

Claim (Index 3):
The system of  claim 2 , wherein, to directly heat the first plurality of streams, the plurality of heat exchangers comprises:\n a first heat exchanger configured to heat the acid gas regenerator bottoms stream in the amine regeneration plant using a branch of raffinate column overheads stream in the aromatics plant xylene products separation unit; a second heat exchanger configured to heat a branch of the stripper bottom stream in the sour water stripper plant using a diesel stripper bottom stream in the diesel hydro-treating plant; a third heat exchanger configured to heat a branch of the stripper bottom stream using a branch of the extract column overheads stream in the aromatics plant xylene products separation unit; a fourth heat exchanger configured to heat a branch of the amine regenerator bottoms stream in the sulfur recovery plant using a feed stream to a first stage reaction cold high pressure separator; a fifth heat exchanger configured to heat a branch of the C3/C4 splitter column bottom stream in the gas separation plant using the diesel stripper bottom stream exiting the second heat exchanger; a sixth heat exchanger configured to heat a branch of the de-ethanizer column bottoms stream in the gas separation plant using the diesel stripper bottom stream exiting the fifth heat exchanger; a seventh heat exchanger configured to heat a branch of the benzene column bottoms stream in the aromatics complex benzene extraction unit using a branch of the raffinate column overheads stream; and an eighth heat exchanger configured to heat a branch of the raffinate column bottom stream in the aromatics complex benzene extraction unit using a feed stream to the second stage reaction cold high pressure separator in the hydrocracking plant.
