A hermetically sealed oil-free turbocompressor system has been developed and introduced to answer the multicycle high flow-in/ flow-out capability on very short notice demanded by the modern gas storage market. This compressor system has been installed in two gas storage facilities and fulfilled the demands and expectations of the market and storage operators. The initial installation experienced several issues that temporarily reduced the availability for the first years of operation. These issues have been addressed and permanently fixed. The second installation did not experience these issues proving that the lessons were learned, solved, and successfully implemented. The hermetically sealed oil-free turbocompressor system was also shown to provide an attractive solution to gas compression applications for which environmental constraints of emissions, footprint, location, or health and safety are present. Because of the positive environmental attributes there is increasing demand to apply this hermetically sealed oil-free compression system to upstream oil and gas process such as offshore unmanned platforms and subsea gas compression installations. To answer these demands the hermetically sealed oil-free compressor system will be adapted to handle corrosive gases typical of these upstream processes. The initial step of this adaptation has already been accomplished with the introduction of a canned magnetic bearing.
