Expansion Systems Turbine

The turbine expansion low-temperature liquid recovery system differs from the choke or valve expansion in that the turbine turns a shaft from which work is extracted. Technical Data used in the field explained in petroleum courses in Islamabad.  A typical turbo-expander process is The gas enters through an inlet separator with any liquid separated at this point being introduced to a low point in the stabilizer tower. The gas then goes through heat exchange with the cold gas leaving the stabilizer. Another separator is installed if sufficient liquid is formed in the gas-to-gas exchanger with the liquid being introduced at an intermediate point in the stabilizer. The cold gas then flows to the expander where the pressure is reduced and low temperature achieved. The gas and liquid mixture  leaves the expander and flows to the separator that normally is on top of the stabilizer column. Sales gas flows back through the exchanger and may be compressed in the direct-connected centrifugal compressor before being put into the sales gas line. Since extremely low temperatures are reached in a typical turbo-expander plant, dehydration normally is a first step though some plants do use alcohol injection. Some more details of petroleum courses in Islamabad are as under.

The gas frequently is expanded below sales gas pressure and then recompressed to make use of the work that must be extracted from the shaft of the turbine. The stabilizer is either a demethanizer or deethanizer with the mixed hydrocarbon product being sold.

A fairly recent development in gas processing, the turbo-expander process is one of great simplicity and ease of operation. The favorable operating characteristics allow the plant to run unattended through long periods and its simplicity and relatively low investment cost make it an attractive option.
