Abstract

The present study deals with three case studies are discussed in detail. All cases had been considered as retrofitting problems and solved very precisely considering existing fixed network costs, present cost of power consumption and recent market price of different sizes of pipes. The first case study involves four processes and single contaminant problem and three approaches of water minimization i.e. reuse, recycle reuse, regeneration reuse are applied. The GAMS software using CONOPT was used to mathematical programming. The second case study is identified as a multi contaminant, reuse problem. The results obtained from the present analysis is compared well and validated with the ASPEN WATER and WATER PINCH software's which uses mathematical programming and pinch technology. The third case study is also multiple contaminant problem which involves eight operations and only water reuse approach is applied. The results are also verified with both software's solutions. The initial fresh water consumption is 185 tph and after modification using mathematical programming it reduces to 90 tph (reuse), 90 tph (recycle reuse) and 46 tph (regeneration reuse).
