Retrofit of Water Networks in Process Plants

چکیده
In this paper, we present a methodology for the retrofit of water utilization systems using mathematical optimization. The problem consists of determining the best re-piping and the capacity of a new treatment unit (if any) to be introduced to generate the best retrofit. Instead of reducing water consumption, or maximizing savings, we resort to analyze the problem using a more comprehensive view of savings and return of investment (ROI) within feasible freshwater usage ranges. The example shows that the solutions where savings and ROI are maxima are remarkably different.

متن کاملProfit-based grassroots design and retrofit of water networks in process plants
In this paper, we present a methodology for the grassroots design and/or retrofit of water utilization systems using mathematical optimization to maximize net present value (NPV) and/or return of investment (ROI) insteadofminimizing freshwater consumption. The examples show that the solutionswhere savings and/or profit are maximized can be different from those where freshwater is minimized. The...
متن کاملRetrofit of Water Network with Regeneration Using Water Pinch Analysis
This paper presents the development of a new systematic technique for the retrofit of water network with regeneration based on water pinch analysis. The procedure consists of two parts: retrofit targeting and design for a water network with regeneration unit(s). In the targeting stage, retrofit targets (utility savings and capital investment) were determined for a range of process parameters (t...
متن کاملDay-ahead economic dispatch of coupled desalinated water and power grids with participation of compressed air energy storages
Nowadays, water and electricity are closely interdependent essential sources in human life that affect socio-economic growth and prosperity. In other words, electricity is a fundamental source to supply a seawater desalination process, while fresh water is used for cooling this power plant. Therefore, mutual vulnerability of water treatment and power generation systems is growing because of inc...
