Technical and Economic Analysis of Utilization of Turbuexpander in Oil Platforms for Power Generation

Author

Abstract

Turbo expanders are rotary machines which recover energy by the expansion of gas or steam and the transference of it to electrical energy. In the past, these machines were used in reducing-pressure stations of power plants and of big cities. By the development of knowledge, the usage of turbo-expanders in other industries such as gas well has become possible. In this research, at first, the conditions of gas well are studied; then the related process with HYSYS software has been simulated. Regarding software calculations, one observes that it is possible to use 3 turbo-expanders with a total power generation of 12000 kW.   And regarding the economic analysis performed, one can find out thatthe payback period can take around seven years.
