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 1):
A system comprising:\n a first plurality of oil refining plants in a crude oil refining facility, each of the first plurality of plants configured to perform at least one oil refining process; a second plurality of oil refining plants in the crude oil refining facility, each of the second plurality of plants configured to perform at least one oil refining process, the first plurality of plants being different from the second plurality of plants; a flow control system configured to:\n flow a first plurality of streams in the first plurality of plants to a plurality of heat exchangers, wherein the first plurality of plants comprises an amine regeneration plant comprising an acid gas regenerator bottoms stream comprising a weak amine salt, an aromatics complex benzene extraction unit benzene column bottoms stream, a raffinate column bottom stream, a naphtha splitter column bottom stream, the aromatics complex comprising at least one of benzene, toluene or xylene, a sour water stripper plant comprising a stripper bottom stream, a sulfur recovery plant comprising an amine regenerator bottoms stream, a gas separation plant comprising a C3/C4 splitter column bottom stream and a de-ethanizer column bottoms stream, wherein a stream in the gas separation plant comprises at least one of C2 to C4 flows, \n flow a second plurality of streams in the second plurality of plants to the plurality of heat exchangers, wherein the second plurality of plants comprises an aromatics plant xylene products separation unit comprising a raffinate column overheads stream and an extract column overheads stream, a hydrocracking plant comprising a second stage reaction cold high pressure separator, a product stripper stream, a diesel product stream, a kerosene product cooling stream from a main fractionator column, a kerosene pumparound stream, a first stage reaction feed stream to a cold high pressure separator, and a diesel hydro-treating plant; and \n the plurality of heat exchangers configured to heat the first plurality of streams using the second plurality of streams.
