Utilities boiler-feed water cost

Utility unit costs power 0.8c/kw hr, steam 70c/1000 lb. cooling water 0.3c/1000 al. boiler feed water 3.0c/1000 gal. Hydrogen plant feed and fuel for the complex supphed from H-Oil gases, light ends, and 1 BPSD of product fuel oil. 

To reduce operating costs, the design should consider alternative utility sources high-pressure steam (HPS) and intermediate-pressure steam (IPS), boiler feed water (BFW), and cooling water. 

Allocated costs, Cgnoo nre included to provide or upgrade off-site utility plants (steam, electricity, cooling water, process water, boiler feed water, leMgeration, inert gas, fuels, etc.) and related facilities for liquid waste disposal, solids waste disposal, off-gas treatment, and wastewater treatment. Some typical capital investment costs for utility plants, estimated by Busche (1995), are shown in Table 16.12. Cogeneration plants can provide both steam and electricity by burning a fuel. When utilities, such as electricity, are purchased firom vendors at so many cents per kilowatt-hour, that cost includes the vendor investment cost. Thus, a capital cost for the plant is then not included in the capital cost estimate.
