Pinch analysis is a methodology for minimising energy consumption of chemical processes by calculating thermodynamically feasible energy targets (or minimum energy consumption) and achieving them by optimising heat recovery systems, energy supply methods and process operating conditions. It is also known as process integration, heat integration, energy integration or pinch technology. Downloadable (with restrictions)! This paper presents new pinch targeting approaches to locate the minimum CO2-neutral and low-carbon sources for energy sector planning. Graphical targeting approach is firstly used to locate minimum consumption of low-carbon source for energy sector planning. A novel automated targeting approach is next presented to determine the optimum allocation of energy.

Ian C Kemp, in Pinch Analysis and Process Integration (Second Edition), Publisher Summary. Heat exchanger networks are designed to reach energy targets obtained by the problem table analysis with the help of the pinch design method.
The method is adapted to allow trade-offs between energy, number of units, and capital; and to cover retrofit of existing plants. Constrained heat exchanger network: targeting and design.

The industrial heat exchanger network synthesis (HENS) problem is very complex and involves combinatorial problems in the “matching” between hot and cold streams to enhance heat recovery. Area Targeting of Heat Exchanger Network (Hen) Using a Modified Pinch Technique To cite this article: Onyemachi Jerry Okechukwu and Oluwatosin Sarafa Azeez IOP Conf.
Ser.: Earth Environ. Some researchers pre-set the allocation of the streams ahead of targeting [Polley, G. T., & Panjeh Shahi, M. Interfacing heat exchanger network synthesis and detailed heat exchanger Constrained heat exchanger network : targeting and design book.
A new approach is developed for targeting number of shells of a heat exchanger network, which directly accounts for the temperature cross. It is based on R and G values, where G is a dimensionless.
Due to the rising of energy prices, energy saving became very important. Optimum design of Heat Exchanger Networks (HEN) is a successful way to minimize energy consumption. The present work discusses the design of optimal flexible heat exchanger networks that adapt with changes in streams’ start and target temperatures and heat capacity Cited by: 9.
Important heat exchange also takes place, and the energy efficiency is related to the column design parameters. Part I of this two-part series presents a rigorous targeting methodology to design this multipurpose plant, which can be implemented using a commercial simulator.

(Received 17 March ; final revision received 25 May ; received for publication 8 June Cited by: Heat Exchanger Network with Non-Uniform Heat Transfer Coefficients A well studied process with nine streams (Ahmad and Linnhoff, ) was chosen to study the behaviour of the proposed targeting procedure for systems with non-uniform heat transfer coefficients.
The fourth edition of Ludwig’s Applied Process Design for Chemical and Petrochemical Plants, Volume Three is a core reference for chemical, plant, and process engineers and provides an unrivalled reference on methods, process fundamentals, and supporting design data.
New to this edition are expanded chapters on heat transfer plus additional chapters focused on the design of shell and tube. Security-Constrained Design of Isolated Multi-Energy Microgrids The model satisfies microgrid's electrical and heat transfer network limitations by integrating linear power flow and heat transfer equations.
It captures the efficiency gains from waste heat recovery through combined heat and power technologies, by modeling the interplay Cited by: The book shows how to extract the stream data necessary for a pinch analysis and describes the targeting process in depth.
Other essential details include the design of heat exchanger networks, hot and cold utility systems, CHP (combined heat and power), refrigeration and optimization of system operating conditions.

Targets can also be set for the utility loads at various levels (e.g. steam and refrigeration levels).File Size: 1MB. Pinch technology–based methods to design heat exchanger network are widely used in industry. The PT approaches do not guarantee optimal solution or even near-optimal one.
The pinch design method (PDM) allows calculating network structure and basic parameters of heat exchangers and splitters. Chapter 4: Heat Integration: Targets and Heat Exchanger Network Design. Abstract: Introduction.

Although many approaches to heat-exchanger network design and heat integration in general are available, there is still a gap between academic research and their industrial applications.For energy saving retrofit projects, its economics are usually evaluated in terms of capital investment and payback time.
The capital investment is in direct relation to the total heat recovery area of the network and the payback time factor is base on both the area and the energy savings.
