Pinch analysis approach to carbon-constrained planningfor sustainable power generation

Incorporating sustainable development in the design of mineral processing operations – Review and analysis of current approaches

“…Pinch analysis is highlighted as one of the key methodologies for optimisation, integration and reduction of pollution [67][68][69]. Pinch analysis is typically based on material and energy flows; however, similar methodologies for minimising pollution-related costs are also reported [70,71].…”

Crisp and fuzzy integer programming models for optimal carbon sequestration retrofit in the power sector

“…At the macroscale level, it also becomes necessary to install additional or compensatory electricity generation to make up for the inevitable energy losses incurred by the CC retrofits in the power sector. Previous approaches to the analysis of CCS systems have been demonstrated using the MARKAL optimization model (van den Broek et al, 2008) and using life cycle assessment techniques (Koornneef et al, 2008). Although there are still significant uncertainties with respect to the economics of CCS systems, technical uncertainties lie mainly in life cycle CO 2 emissions as well as the permanence and capacity of carbon storage (Hansson and Bryngelsson, 2009).…”

“…This paper thus deals with problem of planning optimal retrofit of power plants at the sectoral, regional or national level. A similar static problem has been addressed in our previous work (Tan et al, 2009) which uses a graphical pinch analysis approach, but an improved discrete mathematical programming formulation is presented in this paper. Furthermore, fuzzy variants of the crisp (non-fuzzy) optimization model are introduced to account for conflicting goals as well as parametric uncertainties.…”

“…Crisp linear integer programming model Tan et al (2009) developed a graphical pinch analysis technique for planning of retrofits in power generation systems. That methodology implicitly assumes a continuous approximation, while in reality the decision will be discrete in nature; i.e., a power plant is either retrofitted or it is not.…”

“…The continuous domain of the pinch approach and its linear programming (LP) equivalent is an approximate solution only (Tan et al, 2009), which applies best to problems involving a large number of power plants.…”
