A chemical plant currently purchases 7.5 x 104 MW.h of electricity annually (300 days) from the local utility provider. A 25 year old boiler in the local providers facility provides 2.5 x 107 kg of process steam at 20 bar. Consider the feasibility of a new system to meet the need of the steam and electricity. This system will use turbine to produce the electricity and a heat- recovery steam generator to produce the steam. Write a technical proposal for your proposed system

How do i even start the comparison when there is no data except for the 2 values above? where do i get the values for comparison of a boiler, hrsg and turbine? In addition, don't they all work together in a cycle?
