Abstract
The Oil and Gas Gathering and Processing facilities at West Kuwait field of Kuwait Oil Compnay operates turbine<br>driven multistage (LP/HP) centrifugal compressor for transportation of produced gas. The main challenge for these<br>facilities is to operate it at lower production capacities at many instaces due to various reasons. The crude oil<br>processing units of these facilities were able to operate smoothly for as low as 25% of design capacity. However,<br>the turn down ratio for gas compressors was limited to 55%. This limitation was resulting in offloading of<br>compressor and subsequent gas flaring when facility was operated at lower production rates.
