Dear Mr.Rheuban,
I’m a chemical engineering student at Sharif University of Technology,Iran.
I’m really interested in this subject because of its relevance to my MSc thesis and I was wondering if you happen to know any specific professor and(or) university that are currently working on this matter.
thanks a lot

Bestnaft: I would recommend that you contact one of the turboexpander suppliers listed in the comment above to get more information about how variables in a specific application can be controlled.

In above article several process variables like inlet/outle pressure & temp. have considered. but my question is that how does turboexpander control system work to control mentioned above variables? any comments or information is appreciated.
best regards

Use of Expansion Turbines in Natural Gas Pressure Reduction Stations

We have a project in Pakistan with SNGPL where we have 60 nm3/hr gas flow at 70 bar with required let down to 10 bar. At this moment we have quotes from various companies and would like to make a techno financial feasability of our project. Siemens have quoted a modified steam turbine to use as a gas expander ( so far lowest capex cost )and are intending to use a 1.5 MWe gas turbine to heat the gas. At the outlet we intend to use the gas to produce refrigeration in an ammonia absorber unit. Would you be able to do the engineering approach,prepare a techno financial feasability for our intended project ?

Regards, Suhail Husain.
