Energy-environment closed-loop through Oxygen Pinch

Process integration, modelling and optimisation for energy saving and pollution reduction

“…The strive to design more cost efficient waste treatment systems inspired yet another extension of the pinch principle -the Oxygen Pinch Analysis [13]. The idea was to target prior to design the ideal minimum oxygen demands for micro-organisms aeration.…”

Pinch analysis approach to carbon-constrained energy sector planning

“…Analogies between heat and mass transfer led to the field of mass pinch analysis, which is concerned primarily with the efficient use of industrial solvents [3,4]. This field also led to the specialized application of pinch analysis tools to industrial water utilization [5][6][7][8][9][10][11][12][13][14][15][16], decentralized effluent treatment [17], cooling water network design [18,19], oxygen integration for wastewater treatment [20][21][22] and hydrogen integration in refineries [11,23,24].…”

Pinch Methods for Efficient Use of Water in Food Industry: A Survey Review

“…Regarding literature, pinch analysis was initially developed for heat integration [1]. By analogy with the thermal pinch, further applications are developed in various fields, especially, mass integration [2], design and management of hydrogen networks [10], minimization of oxygen consumption of the microorganisms used for waste degradation [11], emergy analysis [12,13], CO 2 emission targeting [14,15], and supply chain management [16]. Development in energy integration, territorial energy plan and hydrogen network management are addressed in detail.…”

“…To improve energy performance, it is essential to minimize the supply of oxygen, which is a very energy-intensive operation. For this purpose, oxygen pinch analysis has been developed by Zhelev and Ntlhakana [11]. This method aims to help with designing the wastewater treatment systems with cost efficiency.…”
