Pinch Analysis and Process Integration: A User Guide on Process Integration for the Efficient Use of Energy, Second Edition

By Ian C. Kemp

Glossary of Terms

Appropriate placement: Positioning of utilities, heat engines, heat pumps or an extracted process (e.g. separation system) above or below the pinch and grand composite curve for best overall energy performance.
Background process: The stream data for the remainder of the process after the extracted streams have been removed.
Balanced composite curves: Composite curves including the hot and cold utility streams.
Balanced grand composite curves: Grand composite curves including the hot and cold utility streams.
Balanced grid: Network grid diagram including the hot and cold utility streams.
Cascade: Set of heat flows through a heat recovery problem, in strict descending temperature order (as calculated in Problem Table analysis -

See also Problem Table.
Cascade analysis: The method of batch process analysis based on breaking the process into time intervals and developing time-dependent heat cascades.
Cold stream: Process stream requiring heating.
Composite curve: Combined temperature-enthalpy plot of all hot or cold streams in a problem.
CP-Table: Tabulated values of stream heat capacity flowrates, immediately above or below the pinch.
Cycle time: The total duration of a batch.
Cyclic matching: Repeated matching of pairs of process streams.
Data extraction: Definition of data for energy integration studies, from a given flowsheet.
Debottlenecking: Increasing the production capacity of a plant by identifying and removing rate-limiting steps, such as slow processing stages or heavily occupied equipment items.
Direct heat exchange: Heat exchanged between two streams in the same time interval of a batch process.
Direct contact heat transfer: Heat exchanged by two streams which...
