Turbine Expanders

is used where small cooling capacity (up to 100 kWt) is required and expander power conversion into electric power or gas compression is not economically feasible.

has much more extensive application. Gas is compressed in a centrifugal compressor after heavy hydrocarbons separation in a steam-and-water separating drum. The unit has a common shaft with one of expander wheels and one compressor wheel which are shaft opposite. This turbine expander type is used in process cycles for decrease in gas temperature (refrigeration) and for process gas pressure increase due to compressor stage operation.

is used for energy generation (with refrigeration) in process units and at gas distributing stations during compressed gas energy regeneration (utilization).

power: from 100 to 50000 kWt

inlet pressure: to 150 atm

capacity: up to 60 MCMPD;

inlet temperature: from -196°C

expander isoentropic efficiency coefficient: up to 90% (depending on condition combination)
