Recycle gas comp. driven source change from HP to electric
Recycle gas comp. driven source change from HP to electric
(OP)
Recently we are thinking changing recycle gas compressor driven source from HP steam(Pressure 40 Kg/cm2, 400'c) to eletric power in our hydrocracker unit considering refinery steam balance. Re this matter, would you guys please comment on the followings.
a) Merits and demerits of steam driven comp. vs.
electric driven comp.
b) Any experience of eletric driven recycle gas comp.
in high pressure such as hydrocracker.
c) Reliability of each driven comp.
d) Steam driven comp seems to be designed generally
,inform me the reason why, if any.

The compressed gas won't care if the compressor was driven by a competently-designed steam turbine or a competently-designed motor. I'd have to have a really compelling reason to invest the capital and bear the operating cost of the change over.

Recently, our company is considering co-generation capacity increase in our turbo-generator operated around 60 ~ 70% of its design capacity usually, by minimizing low efficiency steam turbine usage. With this way we can save purchased electric power cost from national power generation company which is somewhat normally expensive.
Also, we can increase critical power capacity. Thses are the considerations of our refinery.
Again, is there any experience of electric motor for recycle gas comp. in hydrocracking units ? Is IT POSSIBLE TO CONTROL FLOWRATE ? Hope an answer.
