ohk, let me make it more clear for you,
the situation is we have a boiler generating steam at 23.5 barg, which is throtlled down to 12 barg for import/ export, this 23.5 barg steam is throttled down to 3 barg by another valve to use in heat exchanger, and then this 23.5 barg steam is throttled down to 0.20 barg to use in deareator by another valve, so i was thinking if we have a a system such that we throttled down 3 barg steam to 0.20 barg steam, then that would be beneficial as in, the pipeline will need less permissible safe wroking pressure, less heat losses due to radiation, no need of high pressure valves for throttling etc.
But then to make a new pipeline will require cost analysis, and hence i wanted to know what calculation can i do to prove that throttling 3barg to 0.2 barg will be beneficial in terms of profitability.
