Optimal water purification using low grade waste heat – an ecological proposal
Sustainable process-product development & green chemistry
Sustainable & Clean Technologies-I: Extraction & Remediation (T1-4P)
Keywords: heat pump, water purification, waste heat, thermodynamic model
An ecological proposal for rational energy saving using wasted heat is shown. Thermodynamic-mathematical model is described like a choice effort for water purification from waste heat. This paper describes computing results of heat transformer operation for water purification using low grade or waste heat. Equations, used parameters and simplifications in the model are described. The parameters in the carried out study are the coefficient of performance (COP) defined for reversed heat pumps and the absorber temperature. Both parameters has been shown and correlated between them. The objective of this work is to show the optimal operating condition for different process witch deliver low grade or waste heat and requires water purification. Assisted computing simulation was used for obtain main results. The conclusion is an ecological proposal for optimal recover of low grade or waste heat. Many operating conditions are shown in graphical form and discussed for different environment conditions.
