Problems solved by technology

For example, such software applications do not systematically address or take into account: stream-specific minimum temperature differences; situations where a hot stream matches a hot stream and / or a cold stream matches one or more cold streams; or where a hot stream is partially converted to a cold stream and / or the case where the cold flow is partially converted to a hot flow

Embodiment Construction

[0080] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, which illustrate embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the illustrated embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout. Prime symbols, if used, indicate similar elements in alternative embodiments.

[0081] As previously indicated, the total energy employed or consumed by the process of the superstructure can be optimized to a global minimum, for example by careful placement and configuration of specific material flows relative to each other and by the application of heat exchanger networks (HEN) in order to allow waste heat recovery Level. However, hea...

Abstract

Systems (30), methods, and program product (51) to synthesize a grass-roots heat exchanger network for a plurality of hot process streams (H1..Hn) to be cooled and a plurality of cold process streams (C1..Cn) to be heated according to a plurality of utilities targets, are provided. An exemplary system (30) includes a heat exchange network synthesizing computer (31) and heat exchange network synthesizing program product (51) configured to analyze the waste heat recovery problem without decomposition to produce a result having an optimal number of network heat exchanger units (211, 212, 221, 222) through application of advanced process-to-process matching schemes for both non-constrained and non-thermodynamically constrained problems.

Description

technical field [0001] The present invention relates generally to the field of energy recovery systems, and in particular to systems, program products and methods related to synthesizing a network of heat exchangers for a process or process cluster comprising a plurality of thermal processes to be cooled stream and multiple cold process streams to be heated. Background technique [0002] Many different types of processes consume multiple steam levels and electrical power in order to obtain an output or produce a desired product or compound. For large-scale processes eg consuming large quantities of fuel vapor, it is preferred to optimize energy consumption through careful operation, design or reconfiguration of the plant and equipment used. Furthermore, in some industrial manufacturing processes, there is a need to provide specific streams of material streams at specific temperatures to different types of equipment and machines. These material streams may need to be heated...
