| Abstract: | The principles of non-contact gas lubricated seal and it' s application in the 1300kt/a Hydro-cracking unit in the Refinery of Beijing Yanshan Branch are recommended. The reasons of the seal's failure are analyzed. By meaning of remarking of the seal's gas-supply system, vent system, labyrinth seal and optimizing the compressor's start-up procedure, the seal's failures are eliminated. The service life of the recycle compressor is prolonged. |
