This has been a very important task which this journal has been targeting. As a response to these industrial and societal requirements considerable research effort has been targeted to process integration and process intensification. This article has made an attempt for a short assessment of those advanced engineering approaches. © 2013 Springer-Verlag Berlin Heidelberg.

TS targeting methodology with Time Slices, which is comparable to Heat Integration for batch processes, have been introduced for a short-term, day-to-day analysis. Energy storage facility is integrated in the TS to address the problem of energy supply variation. However, previous studies have mostly dealt with the daily or short term variations. This work introduces an extended methodology for TS integration for the long-term energy supply and demand planning. The work is important in solving cases with a considerable temporal fluctuation of heat sources/sinks, in order to obtain more energy saving opportunities within a longer period of time (i.e., in the scale of weeks or even months). The energy fluctuation in processing plants may be caused by seasonal climate variations, long-term customer demands or even economic down-turn. Some other possibilities include operability issues and raw material availability. The methodology can also be implemented for district heating and cooling systems in countries with four seasons, assuming energy excess during the summer can be stored for use in other seasons e.g. during the winter. This methodology is demonstrated by a case study which involves integration of batch processing plants and space heating system together with cooling system which only operates during certain periods of time. Several scenarios which affect the long-term energy supply and demand have been assumed. © 2013, AIDIC Servizi S.r.l.

Until now, it has not been used to analyze a site's overall sensitivity to plant maintenance shutdown and production changes. This feature is vital for allowing engineers to assess the sensitivity of a whole site with respect to operational changes, to determine the optimum utility generation system size, to assess the need for backup piping, to estimate the amount of external utilities that must be bought and stored, and to assess the impact of sensitivity changes on a cogeneration system. This study presents four new contributions: (1) Total Site Sensitivity Table (TSST), a tool for exploring the effects of plant shutdown or production changes on heat distribution and utility generation systems over a Total Site; (2) a new numerical tool for TSHI, the Total Site Problem Table Algorithm (TS-PTA), which extends the well-established Problem Table Algorithm (PTA) to Total Site analysis; (3) a simple new method for calculating multiple utility levels in both the PTA and TS-PTA; and (4) the Total Site Utility Distribution (TSUD) table, which can be used to design a Total Site utility distribution network. These key contributions are clearly highlighted via the application of the numerical technique to two Case studies. © 2012 Elsevier Ltd. All rights reserved.

However, exploiting heat recovery on Total Site level offers additional potential for energy saving (Klemeš et al., 1997). The current work deals with the evaluation of the capital cost for the generation and use of site utilities (e.g. steam, hot water, cooling water), which enables the evaluation of the trade-off between heat recovery and capital cost targets for Total Sites. The procedure involves the construction of Total Site Profiles and Site Utility Composite Curves and the further identification of the various utility generation and use regions at the profile-utility interfaces. This is followed by the identification of the relevant Enthalpy Intervals. The lower bound of the required heat transfer area can be then estimated which enables its further use in optimisation procedures. Copyright © 2012, AIDIC Servizi S.r.l.

Process Heat Integration (based on Pinch Analysis) aims to minimise the amount of energy mostly used in industrial processes. It is still an open question how to solve the Total Site targeting problem when different values for the minimum allowed temperature differences (ΔT min) are specified for each process on the site. A single uniform ΔT min for all processes integrated in a Total Site, as practiced to date, cannot be generally optimal. Such an assumption may be too simplifying and lead to inadequate results due to imprecise estimation of the overall Total Site heat recovery targets. The modified Total Site targeting procedure, proposed in this paper, allows obtaining more realistic heat recovery targets for Total Sites. It is illustrated with a case study for Locally Integrated Energy Sectors, also providing a comparison with the traditional targeting procedure and the advantages offered by the modified one. © 2011 Elsevier Ltd.

Sometimes its simplicity is misunderstood. Even PI has some potential pitfalls related to the problem formulation and data extraction. Regardless of the precision used, the results largely depend on solving the correct problem - i.e. if the formulation reflects the reality adequately and if the appropriate data have been extracted. An incorrect data extraction has been the reason for conclusions that PI did not work. When revisiting most of those problems, it becomes obvious that it was not a fault of the PI methodology, but an inexperienced user. Copyright © 2010 AIDIC Servizi S.r.l.

Being closely related to energy supply, they are of strategic importance. Various conferences are being organised for providing international avenues for closer cooperation among researchers. The series of conferences "Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction" (PRES) play a pioneering role in contributing to the solution of the related problems through presenting new methodologies and initiating cooperation among participants that often result in international projects. The PRES conferences have been dedicated both to the theoretical and to the practical components of the problems of energy saving and pollution reduction. The PRES series, established twelve years ago, was originally dedicated to energy integration and improving thermal efficiency. Following the new challenges and priorities the scope of the conferences has been extended to include all energy and pollution prevention related issues. This contribution focuses on the period covered by PRES, reviewing at least some major presentations contributing to the development of process integration and optimisation tools for energy saving and pollution reduction. The development of the mathematical models has been covered as well, since it is closely related to the area. Copyright © 2009, AIDIC Sarvizi S.r.l.

Therefore, the optimal synthesis of utility systems is of central interest to engineers in the process industries. Recently, the problem of the global climate change has brought forward the question of reducing significantly the emissions of greenhouse gases into the atmosphere. In this paper, a new approach is presented for cost-effective de-carbonisation of new utility systems in the process industries. This is based on improved models of utility equipment components and an improved model and procedure for optimal synthesis of utility systems. © 2004 Elsevier Ltd. All rights reserved.
