چکیده

this study aimed to find an appropriate way to minimize water utility in the petrochemical and petroleum industries. for this purpose, tehran oil refinery was chosen to analyze feasibilities of regeneration, reuse and recycling in the water network. in this research, two key contaminants including cod and hardness were analyzed. amount of freshwater was reduced about 180 m3/h (53%) and 216.88 m3/h (63%) regarding cod and hardness respectively. in the next stage, two mentioned contaminants were analyzed simultaneously based on the mass transfer constraints. results showed that the amount of required water was reduced from 340 m3/h to 197.12 m3/h that was about 42%. analyzing both methods clearly demonstrated that amount of required water would be determined by mass transfer of cod. in addition, the method based on multiple contaminants gave more precise results rather than single contaminant.

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Retrofit 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...
