Synthesis of Water Networks Involving Temperature-Based Property Operators and Thermal Effects

Abstract

This paper introduces a systematic approach for water integration in industrial facilities based on properties. New property operators and mixing rules (e.g., for odor and toxicity) are proposed to enable the tracking of stream characteristics and the inclusion in an optimization model. Additionally, the dependence of the properties on temperature is accounted for. The thermal effects upon properties are also considered in the proposed water-network model by including cooling and heating. The proposed model for water integration is based on a recycle scheme that includes regeneration processes to improve the stream properties. Furthermore, temperature-adjusting property interceptors are included in the superstructure of the regeneration network to satisfy the temperature constraints in the sinks and also to improve temperature-dependent properties. The applicability of the proposed approach is shown through several case studies, where methodology comparison is made with respect to the ones previously reported in the literature.

Water and energy integration: A comprehensive literature review of non-isothermal water network synthesis

“…Recently, the study in Rojas-Torres et al (2013) proposed an extension of the previous works on mass/property integration, which considered the temperature-based property operators and thermal effects including heating and cooling within WNs. Moreover, new property operators and mixing rules (e.g.…”

Inflection point method (IPM): A new method for single-contaminant industrial water networks design

“…Disposal streams treatment could be implemented after the water networks design and it has no influence on targets of F W , F R , and the relationship between F W and F R . The environmental constraints (Rojas-Torres et al, 2012;Sotelo-Pichardo et al, 2014) on the concentration of disposal streams are not considered in this work.…”

An MINLP model for the simultaneous integration of energy, mass and properties in water networks

“…Initial efforts have been recently reported for the development of models that simultaneously integrate mass and energy (Savalescu et al, 2005a(Savalescu et al, , 2005bLiao et al, 2011;Martinez-Patiño et al, 2011Tan et al, 2012;Zhou et al, 2012aZhou et al, , 2012bBiox et al, 2012;Rojas-Torres et al, 2013;Ibric et al, 2013;Liu et al, 2013;Kravanja, 2013, 2014). In such works, the contribution of mass integration is typically based on the concentration of contaminants, thus ignoring the role that streams properties play in the design of the network.…”
