Hi,

my company planning to replace gas turbine because of maintenance related issues with electric motors for water injection pumps. Pump data is available and Turbines data is not available. I have simulated these pumps in hysys and found power required about 4700 kw. 

my question is whether it is worthy to replace gas turbines with electric motors or not and whether vendors have ability to successfully replace the gas turbines or not.

Thanks

The rotating equipment vendors can give you answers and advice. Locomotive engines are about this size. It sounds like an expensive project with all the electrical infrastructure needed.

Why would one "replace gas turbines with electric motors", because of "maintenance related issues with electric motors".  That does not make sense.  Please clarify.

That sentence can be read in other ways, too. Try it. Pilesar got it right.

Lateman, understand your point next time will take care.

Now explain it, as already you understand my question.

Thanks

I agree, but lack of punctuation leaves it up to interpretation.  An engineer should know better than to use "text-lish".

High reliability and available excess capacity of your power grid could make this an attractive project, but, to be honest, it is big enough in size that it is usually favored by gas turbine economics, especially if the exhaust steam is utilized.  At present, is your exhaust steam utilized effectively?

No we are not recovering any heat from exhaust gas.

Then, the answer is not intuitively obvious to me.  "The devil is in the details."  Follow your local data, plans, estimates, quotations, judgement, etc. and may the option with the highest financial return win out!
