Capital Cost Assessment for Total Site Power Cogeneration

Industrial regions consume large amounts of energy. A lot of research effort is targeted at improving energy efficiency. Heat recovery on Total Site level can provide a considerably high potential for energy saving for industrial areas. It offers opportunities for heat recovery and cogeneration in addition to individual processes. This work deals with estimation of capital cost for power co-generation, evaluating the potential steam turbine placement for various steam pressure levels. The methodology uses the basic principles of Total Site Integration and adds estimation of capital cost for steam turbines with different capacity, inlet and outlet of steam pressure. It also allows evaluating the trade-off between capital cost and energy consumption for the Total Site Integration.
