Strategic planning for and implementation of reclaimed municipal waste water as make-up to a refinery cooling system
This paper discusses the successful use of treated municipal plant waste water effluent (Title 22) in a refinery cooling water system. Conversion from well water to this make-up water source was preceded by developing a carefully crafted transition plan. Steps were taken to identify key system performance indicators, establish desired performance goals, and implement stringent monitoring and control protocols. In addition, all possible contingencies were considered and solutions developed. Treating Title 22 waters is very challenging and entails risks not associated with normal makeup waters. Several novel on-line monitoring and control tools are available which help minimize these risks while enhancing tower operation. Performance monitoring of critical system parameters is essential in order to provide early warning of problems so that corrective measures can be implemented. In addition, a high level of system automation enhances reliable operation. Corrosion, scaling and microbiological performance of the system with Title 22 water is discussed in comparison to previous well water make-up.
