Process integration analysis and improved options for an MEA CO2 capture system based on the pinch analysis

Pinch analysis, as a technique for optimising resource utilisation and promoting environmental sustainability: A review of recent case studies from the developing world and transition economies

“…This further reinforces the usefulness of pinch analysis as an enabling tool for interventions facilitating global, economy-wide sustainable development. As expected, power pinch analysis dominates with heat energy recovery being the focus in 71 publications, vis--vis the optimisation of utilisation of electrical energy (31). It follows, referring to the legends in Figure 4, that optimisation of energy directly results in reduction in the consumption of fuels.…”

“…Many researchers from India, Malaysia, the Philippines, Iran and China have, by availing of CEPA as a tool, shown how the installation of CCS systems can be optimised, while making sure that the power output and thermal efficiency of the power plants alongside them are not adversely impacted. The author would like to refer to Tan RR et al, [28] Harkin et al, Wang Z et al, [29] Ooi et al, [30] Zhang K et al, [31] Priya & Bandyopadhyay (2015A) and Valiani et al, [32] in this context.…”

Optimization and energy integration of heat recovery and power generation system

“…The typical value for the pinch temperature difference is between 8 and 30°C. Figure 6 Pinch temperature difference vs. normalised gross power Figure 6 shows the relationship between pinch point temperature difference and gross power, which is normalised to the gross power at a pinch temperature difference of 15 To examine the impact of heat source fluctuation on the performance of a designed power generation system, an HRSG of Model A is configured, in which inlined bare tubes are used. The operating pressure is 18.6 MPa, and the steam temperature is 320 °C.…”

“…The third strategy is energy integration between the original industrial process and the heat recovery power generation system. Energy intergation has been widely adopted in CO 2 capture process in coal-fired power plant [15,16], Kalina cycle process in combined heat and power plant [17], and fired heaters [18].…”

Optimizing Waste Heat Utilization in Vehicle Bio-Methane Plants

“…Therefore, it was necessary to optimize the performance of the heat exchange network further (See Figure 7), with analyses carried out to evaluate whether: (a) a heat exchanger was passing through the pinch point; (b) there was a cooler exchanger above the pinch point; or (c) there was a heat exchanger below the pinch point [23,24].Two irrationalities in the vehicle bio-methane plant system were identified, the nature of which are described below:…”
