| Abstract: | This paper points out with an example the importance and complexity of constructing or retrofitting a steam supply and district heating system in petrochemical industry according to optimization principle A method and tool to carry out the optimal planning of the system is presented.Based on the existing steam and space heating loads and their expansions,original configuration and retrofit options of the heat sources in a practical system,energy prices,economic indices and other conditions,an optimal retrofit option of the system has been obtained The optimization of operation dispatching of the system in summer season has also been completed The results of this study show that both economic and energy conservation benefits of the optimal option can reach around 7 percent,and payback period of investment for the retrofitting is 3 years |
