Turboexpander-Generator Low Capacity (4-5KW)

07/11/2010 11:03 PM

Hai everyone, I am having a problem here, i am handling a project here and i want to use turboexpander (using natural gas) but the capacity only for about 4-5KW. Further i will couple the turboexpander to drive my generator in order to generate electricity. Is there any idea names of vendors or brands which have the low capacity turboexpander ? Thank you for your information and attention. Best Regards, Arii Bowo Yudhaprasetya

A few details - expanding NG from liquid to gas or from what pressure to what pressure etc would help in deifning an answer. Little expanders are often used in the air separation industry.

I would suggest that you look at a machine like the Mafia-Trench. They make expanders for the air separation industry that will cope with 100 bar.

To the best of my knowledge they have been bought out by Atlas Copco.

Mafia Trench were good to deal with - small enough to care about business and they knew what they were talking about.

Hope it stayed the same.

Two companies come to mind.

First is Kobelco, EDTI located in Corona, CA.

Second is Rotoflow, a BU of GE.

Both firms have the expertise and product offering to get you information.

Thank you very much for the respond.

Anyway i am still trying to discuss with the LINDE, the rest of it gave me the same answer "no product".

Anyway if someone still have another name of vendor or manufacturing company to order that stuff, i would be thankful..

Best Regards,

Arii

Linde buys from a 3rd party.

Don't understand - the rest of it gave me the same answer "no product".

The website for Mafi-Trench (now Atlas Copco) is http://www.atlascopco-gap.com/

"Don't understand - the rest of it gave me the same answer "no product"."

it means,,,i've tried to contact like INGERSOLRAND, SIEMENS, GENERAL ELECTRIC, MANTURBO, ATLASCOPCO, SOLAR TURBINE, INDOTURBINE and they gave me answer "no product" because of the capacity of my turboexpander is too small.

Or maybe, someone has a recommended manufacturing company indeed.

I would be thankful if someone knows about that.

To the best of my knowledge, there are not any expander manufacturers in the 4-5 kW range. The only possible product that may work for you would be something like a converted refrigeration compressor (a screw expander) although using something like this in natural gas service will prove to be difficult.

If your application was 100 times the size then the traditional suppliers could help you.
