It involves isolating CO2 from exhaust gases and then storing it in an appropriate natural reservoir that acts as a sink. Therefore, CCS is able to prevent CO2 from entering the atmosphere. In this work, a continuous-time mixed integer nonlinear programming (MINLP) model for CO2 source-sink matching in CCS systems is developed; the initial model is then converted into an equivalent mixed integer linear program (MILP). It is assumed that in CCS systems, CO2 sources have fixed flow rates and operating lives, while CO2 sinks have an earliest time of availability and a maximum CO2 storage capacity. Thus, the resulting optimization model focuses on important physical and temporal aspects of planning CCS. The usefulness of the model is illustrated using two case studies.

Flowrate targeting algorithm for interplant resource conservation network. Part 2 / Irene M. L. Chew in Industrial & engineering chemistry research, Vol. 49 N° 14 (Juillet 2010)

M. L.; Foo, D. C. Y.; Ng, D. K. S.; Tan, R. R. Flowrate Targeting Algorithm for Interplant Resource Conservation Network. Part 1: Unassisted Integration Scheme. Ind. Eng. Chem. Res. DOI: 10.1021/ie901802m.) proposes a systematic three-step targeting algorithm for unassisted integration scheme for interplant resource conservation network (IPRCN), where cross-plant streams within the pinch region can be used to achieve minimum resource flow rate targets. However, the unassisted scheme does not hold true for all cases. Part 2 of the series explores additional material recovery to be realized by sending cross-plant streams outside the pinch region. This is known as the assisted integration scheme. Appropriate identification of waste streams as the cross-plant streams is an important step in locating the minimum flow rate targets for these cases. The effect of pinch shifting and the generation of new waste streams are also investigated.

Fuzzy optimization model for source-sink water network synthesis with parametric uncertainties / Raymond R. Tan in Industrial & engineering chemistry research, Vol. 50 N° 7 (Avril 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 7 (Avril 2011) . - [7], pp 3686–3694 Titre : Fuzzy optimization model for source-sink water network synthesis with parametric uncertainties Type de document : texte imprimé Auteurs : Raymond R. Tan, Auteur Année de publication : 2011 Article en page(s) : [7], pp 3686–3694 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Optimization  Water  Network Résumé : Source-sink problems occur in various process systems engineering applications, such as the design of water reuse systems and resource conservation networks. Such problems may be solved using alternative approaches, including graphical pinch analysis and linear programming. In most cases, it is normally assumed that the stream flow rates and quality levels are deterministic. This paper presents a fuzzy mathematical programming model for the synthesis of water networks when the model parameters exhibit fuzzy uncertainties. The modeling approach is illustrated for three water network case studies adapted from literature. These illustrative examples cover concentration- and property-based stream quality indices, as well as single- and multiple-plant water integration.
