Profit-based grassroots design and retrofit of water networks in process plants
نویسندگان
چکیده
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. They also differ ccepted 1 October 2008 vailable online 21 October 2008 eywords: ater systems ater reuse from each other when ROI or NPV are used. In addition, when the NPV objective is used, the optimum solutions also vary depending on the interest rate used to calculate the discount factor. © 2008 Elsevier Ltd.

A robust method to obtain optimal and sub-optimal design and retrofit solutions of water utilization systems with multiple contaminants in process plants
In this paper, a simple neu approach for the grassroots and retrofit design of water utilization systems with multiple contaminants is presented. This approach uses a combination of mathematical programming and necessary conditions of optimality to automatically generate the optimal solution featuring minimum capital and operating costs. This paper presents the only existing method to solve thi...
متن کاملRetrofit of Heat Exchanger Networks Considering Existing Structure: A New Targeting Procedure
A new retrofit targeting procedure, based on pinch technology has been developed. The new procedure considers existing structure of a given network and finds the most compatible configuration with the network. To achieve this aim, the procedure uses a linear programming technique that maximize the compatibility. Good compatibility between old and new networks helps to make the best use of c...

Side channel spillways have a common usage in conveyance and distribution networks, high dams, water and wastewater treatment plants, and surface drainage networks. A side channel carries spatially varied flow with increasing discharge and their water surface profiles is a main feature in the design process. Usually, the bottom width of the channel is flared in the flow direction and an end sil...
