| Refrigeration |
| Refrigeration plants are widely used to separate natural gas liquids (mostly propane and heavier components) from the natural gas stream that comes from individual gas and oil wells, and other sources. In the straight refrigeration process, the natural gas stream is chilled to around -30°F with an external propane refrigeration system. The condensed liquids (NGLs) are separated in a low temperature separator and stabilized in a deethanizer column and the overhead gas from the deethanizer column is compressed, cooled and recycled to the inlet gas stream again for further processing. The NGLs (Propane + components) collected in the deethanizer column are pumped out to storage systems. |

| Air/Nitrogen Injection |
| An Air/Nitrogen Injection application uses compressors for injection of air or nitrogen for under-balanced drilling of oil and gas wells. Under-balanced drilling is defined as the practice of drilling a oil or gas well with the well bore fluid gradient less than the natural formation gradient. The bottom hole circulation pressure, which is exerted by the injected gas is lower than the formation pressure, thereby permitting the well to flow while drilling. Under-balanced drilling technology has saved the industry millions of dollars by increasing the amount of recoverable oil and gas within a shorter period of time. |
